A1P Series Single Phase SCR Power Controllers

A1P Series Single Phase SCR Power Controllers

The A1P is a proportional, infinitely variable power controller capable of delivering 0-97% of the applied line voltage to the directly connected electric heaters. The A1P will not control transformers or motors. This is accomplished by phase angle firing a pair of inversely connected SCR's. Modular construction allows for simple and solderless field serviceability. There are four field replaceable items:

Printed circuit board
Fuse
Dual SCR package
MOV (metal oxide varistor)
