GENERATOR REGULATOR CONTROL UNIT (GRCU)
The Generator Regulator Control Unit (GRCU) regulates the voltage of a nominal 28VDC/200A generator-starter conforming to MIL-G-6162 for single or multi-engine powered aircraft.  The GRCU provides DC power conforming to limits specified in MIL-STD-704F.  The GRCU is designed to share the current load of a second GRCU to regulate a twin-generator 28 VDC electrical power system.

FEATURES

  • Voltage regulation
  • 7-position voltage setting (27.0 to 29.0 VDC)
  • Reverse and over current protection
  • Overvoltage and undervoltage protection
  • Line contactor control with short circuit protection
  • Generator field control with short circuit protection
  • Floating pins detection protection
  • Current or load sharing (voltage regulation) in a dual configuration
  • Cross-start (current regulation) in a dual configuration
  • Fully digital sequencing control
  • Gen. Out and Degraded indicators outputs
  • Over current discrete output
  • No scheduled maintenance required
