Solid State Relay Module 40A

The Vszerda SSR-40VA is a solid state relay module rated for 40 amps at 24 to 380 volts AC. It accepts an external potentiometer input for adjustable control of connected loads. The unit suits engineers and hobbyists building custom power-switching circuits.

External potentiometer control

Screw terminals provide secure wire attachment for both control and power sides of the circuit. The solid state design eliminates moving contacts for silent operation and long service life. Buyers needing DC output switching or built-in control knobs should look elsewhere.
