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)
