Product Description

AMF Controllers

Salient features of the DGC-7

Protection & Supervision:

  • 3 phase Under & Over, voltage, frequency and voltage unbalance protection for EB supply (True RMS measurement for Voltage)
  • Phase under & over, voltage and frequency protection of Generator supply (True RMS measurement for voltage)
  • User programmable Cranking attempt.
  • User programmable Crank Time and delay between two successive cranks
  • User programmable load transfer to DG delay.
  • Generator over speed supervision
  • Mains Restoration supervision
  • DC Battery Voltage supervision (Under & Over voltage)
  • External fault detection (5 digital inputs)
  • Two Circuit breaker check back inputs.
  • External engine running signal
  • External signal for remote operation
  • DG Fail to start supervision and indication
  • DG fail to stop supervision and indication
  • Unit remains fully operational even if battery voltage falls to zero volts for one sec.

Measurement & Display

DGC-7, equipped with 16 Segment, 21ine LCD display, displays:

  • EB voltages of RYB phase and frequency
  • Generator voltage and frequency
  • DC battery voltage
  • Run Hour time

Programmed values

The display shows the mains voltage parameters while the mains is healthy and automatically switches over to display the generator parameters while the generator is running.
