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.
Price includes full documentation. |
