    The B1P is a proportional, infinitely variable power controller capable of delivering 1-98% of the applied line voltage to inductive loads. This is accomplished by phase angle firing a TRIAC. The B1P is specifically designed to drive transformers, but will drive resistive loads too.

  • A1P--A1P--B2P-150-250-Amp

    The B2P (single phase) and B3P (3-phase) series of controls are a proportional, infinitely variable power controller capable of delivering 0-97% of the applied line voltage to inductive loads. The B2P is specifically designed to drive transformers, but will drive resistive loads too. 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 Varistors)

  • B3P-500-A-without-cover
