How to purchase the real MGR/mager solid state relay

How to purchase the real MGR/mager solid state relay

INTRODUCTION:

"We always believe that a manufacturer or company with excellent quality and service does not have any need to use the brand effect of other companies to promote and sell its products."
 According to customer feedback, they find some companies with confusing brand name and logos (such as meger, rriager, magar, megar, 111agar, which looks similar as mager) on e-commerce platforms, like ebay, alibaba, taobao, tmall. It has been verified that most of these companies were established after 2014, and sell products with the similar appearance and label to ours. Optimistically speaking, their existence also reflects that our products are widely recognized in the market. In order to avoid damage to our brand image, since 2017, we changed the logo from mager to MGR, and redesigned the labels and packaging of all products, and further improved the quality of our products.
Although we have been using positive legal measures to protect our customers from counterfeit and shoddy products, we also hope to help our customers to keep away with these phoneys by better understand our brand and products.

Through this article, you will learn about what is our brand history? What are the purchase channels for our solid state relays? What are the characteristics of our solid state relays? How to avoid the confusing product?

You can quickly navigate to the chapters you are interested in through the Directory below, and the Quick Navigator on the right side of the browser.

1. Introduction of Our Brand

Brand Name

●   Chinese full name: 乐清市美格尔电子电器有限公司;
●   Chinese abbreviation:美格尔
●   English full name:YUEQING MGR ELECTRONIC AND ELECTRICAL CO., LTD.
●   English abbreviation: MGR, or MAGER.
●   Other avaiLabel English name:YUEQING MEIGEER ELECTRONIC ELECTRIC CO., LTD.; YUEQING MEIGEER ELECTRONIC & ELECTRIC APPLIANCES CO., LTD.; YUEQING MEIGEER ELECTRONICS AND ELECTRIC CO., LTD.; YUEQING MEIGEER ELECTRONIC APPLIANCE CO., LTD.; YUEQING MEIGEER ELECTRON ELECTRICAL CO., LTD.; YUEQING MAGER ELECTRON ELECTRICAL CO., LTD.; YUEQING MGR ELECTRON ELECTRICAL CO., LTD.
According to Chinese law, English names can be changed and used at will, as long as they conform to the translation principles. Therefore, Chinese companies may have many English names in addition to the only Chinese name, and these English names vary according to the translation methods of different organizations (which also explains why we have so many English names). However, the English name cannot be officially registered in the industrial and commercial administration of China, nor is it regulated or restricted by Chinese law. Only the Chinese name enjoys all the rights of the company and the brand. Our Chinese name has never changed since it was officially registered in 2001, and we have not registered other branches. Therefore, when choosing a solid state relay, please look for our Chinese name: 乐清市美格尔电子电器有限公司 (hereinafter referred to as MGR, we, us or our). Although the production line of MGR is constantly expanding, its registered place and site have never left Yueqing City, China. (P.S. Yueqing City is a county-level city in Wenzhou City). If you meet other companies that contain meigeer, like Taiwan meigeer (twmgr), Shenzhen meigeer, Hongkong meigeer, Zhejiang meigeer, Shanghai meigeer, Wenzhou meigeer, Yueqing meigeer solid state relay, Yueqing meigeer relay, meigeer electricals (chmgr) and etc., we can tell you with certainty that they have no relationship with us.

Brand History

Since the 1990s, we have been engaged in the development and manufacture of electronic products and solid state relays.

In 2001, we officially registered YUEQING MEIGEER ELECTRONIC ELECTRIC CO., LTD. and started to provide solid state relays for companies across China.

In 2004, we used mager as an English trademark as products flowed into overseas markets through various foreign trade companies.

In 2008, we obtained ISO9001: 2000 quality management system certification. And our headquarters moved to the Beibaixiang Industrial Park.

In 2017, to avoid brand damage and better protect consumer rights, we used a more recognizable logo MGR.

In 2018, MGR cooperated deeply with HUIMU Trade to provide high quality MGR solid state relays and services to the world through HUIMU Industrial. Since then, MGR officially entered the overseas market.

In 2019, due to production needs, the MGR headquarters moved to the newly built MGR building, and MGR still plans to further expand the production line.

So far, we have sold millions of solid state relays. And we have been widely praised by users at home and abroad due to the high quality, the extremely low failure rate of our products. In the future, we will strive for excellence and work harder to help more customers.

2. How to distinguish our solid state relays

First, let us compare our products to those confusing products. Obviously, their logo is so similar to ours, even the design of the label is exactly the same, so that it is hard to distinguish from them at first sight. Actually, most of these companies were established between 2014-2018. Therefore, we are curious about what happened in 2014 and we would like to know what led to dozens of such companies appeared in a short period of time. In order to avoid damage to the brand image and protect the rights and interests of users, from 2017, we redesigned the packaging and labeling, and further upgraded the brand image, product quality and service.

Arc - Short essay

An electric arc is a gas discharge phenomenon in which an electric current is generated by a momentary spark generated by some insulating medium such as air.

Spark - Short essay

SparkSpark is a kind of particulate matter with energy and heat generated by a large amount of electric energy when the contacts of mechanical relays strike together.

Moisture Resistance - Short essay

Moisture Resistance also known as damp proofing ability, is a type of moisture control to prevent the intrusion of humid air (water vapor) into the relay, causing corrosion of mechanical components, short-circuiting of electronic components and etc. Since the solid state relay uses a well-sealed casing, it has better moisture resistance than mechanical relays.

Insulation Material - Short essay

Insulation MaterialInsulation Material is the material for electric insulation use in the electrical and electronic field.

Logic Circuit - Short essay

In computer engineering, logic circuit or logic family may refer to one of two related concepts.  A logic family of monolithic digital integrated circuit devices is a group of electronic logic gates constructed using one of several different designs, usually with compatible logic levels and power supply characteristics within a family. Many logic families were produced as individual components, each containing one or a few related basic logical functions, which could be used as "building-blocks" to create systems  or as so-called "glue" to interconnect more complex integrated circuits.

The list of packaged building-block logic families can be divided into categories, listed here in roughly chronological order of introduction, along with their usual abbreviations:
1. Resistor–transistor logic (RTL)
   1.1 Direct-coupled transistor logic (DCTL)
   1.2 Resistor–capacitor–transistor logic (RCTL)
2. Diode–transistor logic (DTL)
   2.1 Complemented transistor diode logic (CTDL)
   2.2 High-threshold logic (HTL)
7. N-type metal–oxide–semiconductor logic (NMOS)
   7.1 Depletion-load NMOS logic
   7.2 High-density nMOS (HMOS)

Logic Circuit

Vibration Resistance - Short essay

Vibration Resistance also know as vibration proofing, is an ability of a device to protect against vibration. Many equipments have high requirements on the physical environment of work, and their performance is susceptible to vibration or even malfunctions and malfunctions. Solid state relays have better vibration resistance than mechanical relays.

Corrosion Resistance - Short essay

Corrosion ResistanceThe ability of metallic materials to resist the corrosive effects of surrounding media is known as corrosion resistance. Solid state relays have better corrosion resistance than mechanical relays.

Mildew Resistance - Short essay

The Mildew Resistance or mold-proof product has the ability to inhibit the growth of mold spores and the growth of mycelium.Solid state relays have better Mildew Resistance than mechanical relays.

Electrical Level - Short essay


Electrical level type
Electrical Level or logic voltage levels. In logic circuits, two voltages are commonly used to represent two logic states, but sometimes two currents are used to represent them. High and low thresholds are specified for each logic circuit. When below the low threshold, the signal is "low". When above the high threshold, the signal is "high". Intermediate levels are undefined, resulting in highly implementation-specific circuit behavior.

Contact Bounce - Short essay

Contact Bounce, or contact chatter,contact jitter usually occurs at the contacts of mechanical relays. When the mechanical contacts are connected or disconnected, due to the elastic action of the mechanical contacts, the mechanical relays will not be turned on steadily when connected, nor will be turned off imitately when disconnected. Therefore, there is a series of jitters at the moment of connecting or disconnecting, ans this phenomenon is contact jitter.

Switching Speed - Short essay

Switching SpeedSwitching speed or switching rate, is the switching  frequency of the mechanical relays and the solid state relays. The higher the switching frequency (or the shorter the switching time), the faster the switching speed.

Mechanical Failure - Short essay

Mechanical failure refers to a significant reduction in the performance of the equipment and is below the minimum required by normal requirements, and is no longer able to maintain normal operation, due to mechanical wearspark,electric arc,contact jitter and etc. Equipment failures generally include:
   (1) Destructive failures that cause the equipment system to lose functionality immediately.
   (2) Performance failures associated with degrading device system performance.

Mechanical Wear - Short essay

Mechanical WearMechanical wear refers to the friction between the friction surfaces that are in contact with each other to produce relative motion, which will produce the frictional resistance of the movement of the tissue, causing the consumption of mechanical energy and conversion to release heat, causing mechanical wear.

Electro-Magnetic Compatibility - Short essay

Electromagnetic compatibility (EMC) is the branch of electrical engineering concerned with the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (EMI), radio frequency interference (RFI) or even physical damage in operational equipment. The goal of EMC is the correct operation of different equipment in a common electromagnetic environment.

Electro-Magnetic Interference - Short essay

Electromagnetic interference (EMI), also called Radio-frequency interference (RFI), is an interference caused by Electromagnetic Radiationgenerated by an interference source to cause malfunction of an electronic device. The electromagnetic interference can cause abnormal operation of the circuit and even directly damage the device.
Types of electromagnetic interference: EMI can be divided into several categories according to the source and signal characteristics. The origin of interference, often called "noise" in this context, can be man-made (artificial) or natural. 

Radio Frequency Interference - Short essay

Radio-frequency interference (RFI), also called Electromagnetic interference (EMI) when in the radio frequency spectrum, is a disturbance generated by an external source that affects an electrical circuit by electromagnetic inductionelectrostatic coupling, or conduction. The disturbance may degrade the performance of the circuit or even stop it from functioning. In the case of a data path, these effects can range from an increase in error rate to a total loss of the data.

Transistor - Short essay

 A transistor, or triode is a electronic component used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually as discrete Components, but many more are found embedded in integrated circuits.

According to the structure, the transistor can be divided into: BJTSCRTRIACMOSFETIGBT, and etc.

According to the electrical polarity (positive and negative), the transistor can be divided into: n–p–np–n–p (BJTs); n-channelp-channel (FETs).

Electromagnetic Relay - Short essay

Electromagnetic Relays (also known as traditional mechanical relay, Electromechanical Relay, EMR), are widely used in many fields as the earlist relay. Unlike solid state relays(SSR), electromagnetic relays use mechanical action components with contacts as the switching components (such as Coil-Reed Electromagnetic Relay). When the input terminal of the electromagnetic relay is added with control signals, the coil inside the electromagnetic relay is energized by the input current to generate an electromagnetic field to attract the movable component, so that the movable contact in the movable component contacts with the static contact in the non-movable component to turn on the output circuit of the electromagnetic relay. Mechanical relays are composed entirely of simple mechanical components, so its cost is very low, but these movable parts will generate jittersparks , and arcs during operation (which will make contact abnormal and shorten the service life), and also generate electro-magnetic Interference (which will make the input circuit and output circuit unstable). In addition, EMR will be interfered by interference signals, and cannot work in humid environments. Becasue the shortcomings and unreliability performance of electromechanical relays, the solid state relay has gradually replaced the position of the mechanical relay. >>More information about the differences between SSR and EMR>>
