AC Input-AC Output Type Solid State Relay
AC Input-AC Output Type Solid State Relay, AC-AC Solid State Relay, can control AC load circuit through AC control signal.
AC
The current magnitude and direction of Alternating Current (AC) change periodically with time, and the average value in one cycle is zero.
Absorption Circuit
Absorption Circuit, also known as snubber circuit, is an important protection circuit for power electronic components. The snubber circuit can be used not only for the protection of semi-controlled devices, but also for fully controlled devices (such as GTR, GTO, power MOSFET and IGBT).
The basic working principle of the snubber circuit is to suppress the current rise rate (di) of the device by utilizing the characteristic that the inductor current cannot be abrupt, and to suppress the voltage rise rate (dv) of the device by utilizing the characteristic that the capacitor voltage cannot be abruptly changed.
Zero Crossing Detector
Zero Crossing Detector consists of transistors or IC components to detect the load voltage of the solid state relays, only if the load voltage has crossed the zero, the detector will allow the solid state relays to switch the load.
Low Power Device
Low Power Device, also know as input device or control device, is the input signal source of the soild state relays. Solid state relays can control the large current device with the low power signal from the input device.
Terminology Library Location : Home > Terminology Library > Optoelectronic Isolation
Optoelectronic Isolation is a method to isolate the input and output signals physically and electrically by using light as a signal medium to minimize interference between the two signals. Solid state relays use opto-coupler as signal isolation method, so its EMC (the ability to control EMI) is better than mechanical relays.
Power
Power refers to the amount of work done by an object in a unit of time. That is, the power is a physical quantity that describes the speed of work, and can be divided into electric power and power.
The electric power is the physical quantity indicating the current work speed. The power of a electronic component is equal to the power consumed by it in 1 second (t, unit is s) (W, the unit is J), that is, P=W/t.
The magnitude of the electric power is also equal to the product of the voltage across the conductor and the current through the conductor: P = U*I.
For a purely resistive circuit, the calculation formula of electric power can also be expressed as: P=I^2*R and P=U^2 /R.

Actuator
Actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve. In simple terms, it is a "mover". In electronic and electrical systems, actuators are electric motor, solenoid valves, cylinder and etc.
Explosion Proof
In electrical engineering, hazardous locations are defined as places where fire or explosion hazards may exist due to flammable gases, flammable liquid–produced vapors, combustible liquid–produced vapors, combustible dusts, or ignitable fibers/flyings present in the air in quantities sufficient to produce explosive or ignitable mixtures. Electrical equipment that must be installed in such classified locations should be specially designed and tested to ensure it does not initiate an explosion, due to arcing contacts or high surface temperature of equipment. The solid state relays with better explosion proofing than that of mechanical relays can serve in the hazardous locations.
Insulation Resistance
Insulation Resistance is an ability of a device to protect against short circuit and electrical breakdown by using the Insulation Material. Solid state relays have better insulation resistance than mechanical relays.
Mechanical Shock Resistance
Mechanical Shock Resistance also known as shock proofing or toughness, is the ability of a material to absorb energy and plastically deform without fracturing. One definition of material toughness is the amount of energy per unit volume that a material can absorb before rupturing. It is also defined as a material's resistance to fracture when stressed. Solid state relays have better shock resistance than mechanical relays.
