GENERAL NOTES
(1)
Single pair (up to 25A) Double pair* (up to 50A).
*Caution:
User must connect both pairs.
(2)
Option “K” is designed and tested for use with printed circuit boards or ring/fork terminals having a thickness between 0.031 and 0.093 inches (0.79 to 2.36 mm), and loads rated up to 50
Amps. For higher load currents, the “K” standoff temperature must not exceed 105°C. For additional application assistance please contact Crydom Technical Support.
(3)
Output will self trigger between 900-1200Vpk, Min., not suituable for capacitive loads.
(4)
Instantaneous turn-on version is not recomended for capacitive loads. Use zero turn-on only.
(5)
All parameters at 25°C unless otherwise specified.
(6)
Heat sinking required, see derating curves.
(7)
For 40mA minimum current, the voltage drop increases over maximum rated.
(8)
Increase minimum voltage by 1V for operations from -20 to -40°C.
(9)
Turn-on time for Instantaneous turn-on versions is 0.02 msec (DC Control Models).
(10)
All parameters at 50% power rating and 100% duty cycle (contact Crydom tech support for detailed report).
(11)
Load can be wired to either SSR output terminal 1 or 2.
(12)
Elective Input Status LED, “G” option.
(13)
Elective Overvoltage Protection, “P” option.
(14)
Mechanical dimensions vary from G3 models.
For additional information or specific questions, contact Crydom Technical Support.
