SOLID STATE
RELAY REQUIRES ONLY 50uA DRIVE CURRENT
This circuit demands a control
current that is 100 times smaller than that needed by a typical optically isolated
solid state relays. It is ideal for battery-powered systems. Using a combination
of a high current TRIAC and a very sensitive low current SCR, the circuit can
control about 600 watts of power to load while providing full isolation and
transient protection.
