GENERAL NOTES
(1)
Output will self trigger between 900-1200Vpk. Min. power factor 0.7 or higher, not suitable for capacitive loads.
(2) All parameters at 25°C unless otherwise specified.
(3) Heat sinking required, see derating curves
(4) For ambient temperature above 40°C the maximum control voltage must not exceed 250VAC.
(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 Crydom 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
