The Series CW48 has an SCR AC switch
output featuring low off-state leakage
(1mA, snubberless), zero and random
voltage switching and a broadened
operating range (48-660Vac).
This wide range permits optimum
perfomance at voltages from 240 Vac to
600 Vac line voltages.
Manufactured in Crydom's ISO 9001
Certified facility for optimum product
performance and reliability.
