General notes

1) Single pair (up to 25A) Double pair* (50A model only). *Caution: User must connect to 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

3) Instantaneous turn-on not recommended for capacitive loads. Use zero turn-on only.

4) All parameters at 25°C unless otherwise specified.

5) For “S” option, operating voltage frequency is 47-63Hz.

6) For parts with option “S” maximum leakage current is 10mA.

7) Heat sinking required, see derating curves.

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 Internal Snubber, “S” option.

13) Mechanical dimensions vary from G3 models.
