The SAL Power Solid State Contactor has a 22.5mm highly compact design and can be used out-of-the-box with its heatsink for DIN rail mounting. It is ideal for resistive loads because of its zero cross structure.
The new back-to-back thyristors on output incorporate TMS2 technology giving them a long service lifetime with a 24 to 600VAC 50A SCR rating. The derating curve shows the rate of current limitation at 22/32A by the heatsink. The contactor has a wide control range from 3.5-32VDC using the input current limiter, and input is visualized by a yellow LED.
It also offers protection against input over-voltage, and comes with an IP20 protection cover.
