AKGRAD32 : Thyristor / SCR Power controller

Firing modes:

1P / 3P Power control with permanent phase angle with current limitation with or without downstream transformer,
1P / 2P / 3P Power control with permanent Fast Full Wave with phase angle soft-start with or without downstream transformer.

Features:

The 32bits DSP of the AKGrad32 measures and calculates true RMS mains voltage V, current A, power kW and resistor OHM for each phase.

This powerful energy management unit enables:

  1. Patented soft-start firing for any inductive downstream transformer which avoid over current peaks even in cost saving 2-Phases Control.
  2. Unique integrated power savings “SYNCHRO” feature for real-time load management.
  3. Very high accuracy closed loop kW-%-I²-U² regulation with partial/total load failure diagnosis on each phase.
  4. Instantaneous adaption to voltage variations, over currents due to short circuit to ground or load surge.
  5. Phase-Angle soft start for heaters with high cold/hot variations with current limit feature (Molybdenum, SiC, etc.)
