The RFL Model 70A is a "stepless", full wave phase firing temperature controller capable of controlling as accurately as ± 0.05ºC in many applications. Resistive loads from 1 to 15 amps, 115 or 230 vac 50/60Hz can be controlled. Set point adjustment is achieved via internal screwdriver accessible Coarse and Fine controls or with a remote 10,000 ohm potentiometer (RFL #42060 or equiv). A Gain adjustment is provided enabling the bandwidth (sensitivity) of the controller to match the thermal dynamics of the complete system.
