Features:

  • Converts 18.5 to 36 VDC input to 12 VDC ±5% output.
  • Supplies up to 5 A for DeltaV M-series I.S. I/O cards.
  • Supports n+1 power-supply redundancy.
The current ordering configuration is KJ4110X1-EA1 12P1878X032, the DeltaV M-series intrinsically safe system power supply.

It converts nominal 24 VDC input to 12 VDC for DeltaV I.S. I/O cards. The number of cards powered by one supply depends on the installed I.S. card types, and an additional supply can provide n+1 redundancy.

Install the unit in either slot of a 2-wide Power/Controller Carrier. Confirm the full-load mounting orientation, duplicated screw-terminal connections, cable size, and environmental limits before commissioning.

Availability is subject to Apter Power inventory and sourcing confirmation.
