60 Hz PDU Models may be operated at 50 Hz only if unit is NOT equipped with Optional AC Power Monitor

Contact AC General for Technical Assistance if you require 50 Hz operation.

Options:

Remote ON/OFF (Option "R" and "R1")

  • Allows remote control of AC Power Controller up to 150 ft. away (60Hz models only)
  • Low voltage control circuit:
    • 60Hz Models- 24 VAC
    • 400 Hz Models- 24 VDC
  • AMP 9Pin "CPC" style connectors both ends
  • Two types of Remote Control are available:
    • "R" Option System power controlled via (1) lighted toggle switch
    • "R1" Option System power controlled via (2) lighted momentary pushbutton switches

AC Power Monitor (Option "P")

  • Available in 60Hz and 400Hz PDUs
  • "A-B-C" phase rotation protection and AC line UNDER VOLTAGE/Phase Loss protection. Under voltage set point is calibrated (-)15% of ph-ph voltage (Setpoint= 177VAC on 208VAC Phase-to-Phase)
  • Automatically removes all switched power upon AC fault detection within 50 msec
