Product Description

MODEL No EP-844

EP-844

Each Phase Power Factor Controller specially designed for unbalanced loads. Works for both single & three phase systems, maintaining power factor separately for each phase (R, Y, B).


Key Features

  1. Unbalanced Load Support: Specially designed for unbalanced loads (e.g. R Phase 50A, Y Phase 20A, B Phase 10A).
  2. Per-Phase Control: Maintains power factor for R Phase, Y Phase, and B Phase independently.
  3. Display: 20×4 LCD Display with Backlight showing 3-phase Voltage, Current, KW, KVA, PF, KVAR, Hz.
  4. Alarm: On-screen alarm display for Over Voltage, Under Voltage, and Phase Fail.
  5. Security: Easy installation with Password Protection.
  6. No Programming Required: Plug-in terminal connection, front panel mounting.
