GENERAL NOTES
© 2003 CRYDOM CORP, Specifications subject to change without notice.
➀ All parameters at 25˚C unless otherwise specified.
➁ Dielectric and insulation resistance are measured between input and output.
➂ Off-State dv/dt test method per EIA/NARM standard RS-443.
➃ Turn on time for random switching models is 0.1 ms (use suffix when ordering random turn on version)
➄ DC Input circuitry incorporates active current limiter.
Use suffix -120 for 120Vac control and -240 for 240Vac control.
