Panel Mount ‒ AC Output Application Scenarios: Suitable for controlling three-phase motors, heaters, and other equipment. ■ DESCRIPTION KS24 is a three-phase AC output panel mount type SSR (3PST-NO). It offers 4~32VDC input voltage option and three AC output voltage options 380VAC,480VAC and 600VAC as well as four output current ratings from 25A to 80A for selection. The SSR includes an LED indicator to display working status and provides photoelectric isolation between input and output with dielectric strength 4000V . Besides, the phase absence protection type is equipped with an...

■ PRECAUTIONS recommended screw mounting torque as follows: the M4 screw mounting torque range is 0.98~1.37N·m, and the M3 screw mounting torque range is 0.58~ 0.98N·m. 7. It is recommended to use the matched heatsink made by Keysolu. If the user needs to use the home-made heatsinks, please ensure that the temperature of the SSR base must not exceed 85°C. 2. Please coat the SSR metal base with some thermal grease or a thermal pad, and firmly press the SSR against the heatsink to ensure the full adherence, and then screw the SSR to the heatsink. 3. Please wire the screw terminals and tighten...
