DARE Electronics’ solid state relays incorporate advanced microelectronic hybrid technology and are available from low level to 50 amps.
Solid state relays have distinct advantages over electro-mechanical devices including: no contact bounce, arcing or flashing; immunity to contact contamination and oxide formation in dry or normally open circuits; and immunity to shock and vibration thus preventing unwanted contact closures. Furthermore, DARE's solid state relays yield much longer switching life, higher reliability, and reduced electromagnetic radiated and conducted emissions.
Features include:
Optical or transformer input to output isolation
Zero voltage turn-on; zero current turn-off
Logic compatible input current levels
3 phase load switching capabilities
Hybrid microelectronic design
High transient immunity
Fast switching speed
Snap action switching
