Power Controllers

Solid-State Contactors accept potentiometer input.

Power switching products accept 0-5 k potentiometer signal and convert it into time proportional output. With cycling capability of twice per second and set-point resolution of 0.5 sinewave, contactors reduce thermal stress and include finger-safe caged terminals, integral heat sink, and universal mounting bracket for DIN-rail or bolt-on installations. Products are available in single-phase...
