Zero Volt or Instant Switch On
Crydom's LS family of SPST-NO
relays achieves the highest power
switching capability in a PC-mounted
air-cooled package. Output consists
of an SCR AC switch and is
available in zero-cross and random
turn-on (Suffix R).
Advanced features include exceptional
steady state current, plus high
surge ratings. Metal baseplate design
for direct attachment of external
heatsink to achieve higher current
rating.
Manufactured in Crydom's ISO 9001
Certified facility for optimum product
performance and reliability.
