APC-TF Series TECHNICAL SPECIFICATION
The Model APC-TF Series is a new generation SCR Active Power Controllers for use with resistive,
inductive loads. This unit features the optimum conditions heatsinks with remote analog set-point
value for precise control. Basic include diagnostic load failure detection, a wide scope fault
detection. Fault indicates when a shorted device or an open load is detected.
