AC Single Phase SSR Solid State Relay AC SSR of Single Dual In line
Description of AC Single Phase SSR Solid State Relay
Solid State Relay Output Circuit
The most common application of solid state relays is in the
switching of an AC load, whether that is to control the AC power
for ON/OFF switching, light dimming, motor speed control or other
such applications where power control is needed, these AC loads can
be easily controlled with a low current DC voltage using a solid
state relay providing long life and high switching speeds.
One of the biggest advantages of solid state relays over an electromechanical relay is its ability to switch “OFF” AC loads at the point of zero load current, thereby completely eliminating the arcing, electrical noise and contact bounce associated with conventional mechanical relays and inductive loads.
This is because AC switching solid state relays use SCR’s and TRIAC’s as their output switching device which continues conducting, once the input signal is removed, until the AC current flowing through the device falls below its threshold or holding current value. Then the output of an SSR can never switch OFF in the middle of a sine wave peak.
Zero current turn-off is a major advantage for using a solid state relay as it reduces electrical noise and the back-emf associated with the switching of inductive loads as seen as arcing by the contacts of an electro-mechanical relay.
