The newest series of "Hockey Puck"-style solid state relays, the SGX-1505FB Series, has 10 models switching between 10-40 A at up to 380 VRMS. The relays have d.c. inputs, either zero-cross or random turn-on with up to 800 V blocking, and built-in snubbers. They are said to have high surge capability and use photo-isolation for high input to output isolation. The relays are manufactured to ISO-9001 standards.
