480 VAC
PANEL MOUNT SOLID STATE RELAYS
The Sensata | Crydom CW Series Panel Mount AC output Solid State Relays offer a back-to-back SCR output for reliable switching of commercial
and heavy industrial loads. This type of high performing SSR is available with output ratings from 10 Amps up to 125 Amps at 48 to 660 VAC.
The CW Series panel mount solid state relay includes a removable IP20 “touch-safe” cover for added safety and is also available with zero voltage
turn-on (for resistive loads) or instantaneous turn-on (for inductive loads) outputs.

GENERAL NOTES
All parameters at 25°C unless otherwise specified.
“P” option output will self trigger between 450-600 Vpk. Power factor 0.7 or higher, not suitable for capacitive loads.
(3)
Heat sinking required, see derating curves
(4)
For ambient temperature above 40°C the maximum control voltage must not exceed 250 VAC.
(5)
Increase minimum voltage by 1V for operations from -20 to -40°C.
(6)
Turn-on time for Instantaneous turn-on versions is 0.1 msec and 7msec for CWU models.
(7)
AC input models operating range is -20 to 80 °C.
(8)
All parameters at 50% power rating and 100% duty cycle (contact tech support for detailed report).
(9)
Load can be wired to either SSR output terminal 1 or 2.
(10)
Select P option for overvoltage protection.
(11)
For single surge pulse Tc=25°C; Tj=125°C. For AC Output SSRs, AC Rms value of surge current equals the peak value divided by √2 (1.414).
