sensata.comCopyright © 2025 Sensata Technologies, Inc. GENERAL NOTES For additional information or specific questions, contact Technical Support. (1) Single pair (up to 25A) Double pair* (50A model only). *Caution: User must connect to both pairs For higher load currents, the “K” standoff temperature must not exceed 105°C. For additional application assistance please contact Technical Support. (3) Output will self trigger between 900-1200Vpk, Min. power factor 0.7 or higher, not suitable 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) Increase minimum voltage by 1V for operations from -20 to -40°C. (8) Turn-on time for Instantaneous turn-on versions is 0.02 msec. (9) All parameters at 50% power rating and 100% duty cycle. (10) Load can be wired to either SSR output terminal 1 or 2. (11) Elective Input Status LED, “G” option. (12) Elective Overvoltage Protection, “P” option.
