Crydom's CW24 line of solid state relays offer
an SCR AC switch output featuring low off-
state leakage (1mA, snubberless), zero and
random voltage switching and a broadened
operating range (24-280Vac). This wide
range permits optimum perfomance at both
120Vac and 240Vac line voltages.
Manufactured in Crydom's ISO 9001
Certified facility for optimum product
performance and reliability.
