Power Supply:

Note: Please ensure that you are using the appropriately sized DC barrel jack for your particular EVM revision, as these have changed from the E2 to the A revision. An E2 Power Supply can be adapted to a Rev A GP EVM by using an adapter of part number DC PLUG-P1J-P1M
  • DC Input: 12V
  • Revision A and later:
    • The GP EVM Revision A implement a center positive 5.5mm x 2.5mm x 9.5mm Barrel Jack.
    • Recommended mating connector - PJ-080BH.
    • Recommended Power Supply - GlobTek Inc. RR9LE5000LCPCIMR6B ( IEC 320-C6 adapter cords sold separately).
  • Revision E2:
    • The GP EVM Revision E2 implements a center positive 5.5mm x 2.1mm x 9.5mm Barrel Jack.
    • Recommended mating connector - CUI In. PP3-002AH. (“tuning fork” style plug recommended to avoid the possibility of intermittent connections)
    • Recommended Power Supply - CUI In. SDI65-12-UD-P5 (adapter cords sold separately).
    • Example Adapter Cords:
      • CUI In. AC-C7 NA
      • Phihong USA AC15WNA
      • CUI In. AC-C7 UK
  • Status Output: LEDs to indicate power status
  • INA devices for current monitoring
