Solid State Relays 

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
