Series SCR70 is designed to proportion electric power to resistive loads only such as those found on ovens, furnaces and heat sealers. They are not designed to drive transformers or any inductive load. The controllers consist of power semiconductors (SCRs), properly sized heat sinks, trigger circuitry and fuses usually supplied on panels for surface mounting. The controller accepts an output signal such as 4 to 20 mA DC. The power controllers can be supplied as manual controllers with the addition of the manual option module and remote potentiometer.
