Functional Description

IS400JPDFG1A is a DC Power Distribution Module developed by GE. It is a part of Mark VIe Control system. This 125 volt power distribution module accepts redundant 125 volt dc power inputs and distributes power to other system boards. rather than a grounded system, it works with a floating dc bus that is centered on the earth. This detects system ground faults and has a non-hazardous live 125v dc rating.

Features

  • Input A terminal board on the module is powered by a 125 V dc battery. Before being connected to the board via the J1 connector, the power is routed through a 125 V dc 30 A circuit breaker and line filter. The alternating current voltage is then routed to three fused non-switched outputs and six fused switched outputs.
  • The board routes alternating current power to the DACA modules, which convert it to direct current power. DC power is returned and combined with the battery power input. can operate with any combination of one or more inputs active, resulting in a high-reliability 125v dc power source for the control system.
  • The module provides full status feedback via a PPDA I/O pack connection. Feedback includes detection of bus magnitude, ground faults, and excessive ac voltage on the dc bus. Each fused branch circuit is checked for the presence of output power.

Installation

  • The module is vertically mounted on a metal back base in a PDM cabinet. Sheet metal must be connected to the system's protective earth (PE). Terminals DCHI and DCLO receive input battery power. When one or two DACA modules are used, alternating current power is applied to JAF1. JZ2 and JZ3 connectors connect DACA modules.
  • The system's output circuits are connected as documented. A 50-pin ribbon cable from connector P1 to the P2 connector on the board is required for a power distribution system with a power diagnostic I/O pack. Using the P2 connector, this connection can be extended to other core PDM boards.

Grounding

  • Mark VIe systems classify ground into two types: protective earth (PE) and functional earth (FE) (FE). When an entire cabinet or series of cabinets is externally grounded, PE grounding is used.
  • Individual modules, boards, and electronic components are grounded to the chassis or cabinet using FE grounding. Metal mounting supports fastened to the underlying sheet metal of a metal module ground. The ground is applied to the metal switch bodies. Furthermore, when creating the feedback signals seen on P2, the ground is used as a local reference point.
  • The module's sheet metal is insulated from the surface on which it is mounted. This is done specifically to allow the board ground to be defined independently of the mounting surface. board is typically mounted to a back base that is grounded to FE. It would be physically located low in the cabinet, and PE would be provided with a separate ground wire from the module.
  • The ground wire's minimum length is critical for keeping radio frequency impedance low and allowing the input line filters to function properly.

Operation

  • Terminals DCHI and DCLO are powered by a dc battery. It then passes through a 30A dc circuit breaker into a filter assembly beneath the circuit board. The filter output is then routed to the circuit board via a series diode. The JAF1 connector receives alternating current power.
  • The 115/230 V alternating current is routed to two connectors, JZ2 and JZ3, and then out to two modules. The modules convert alternating current to direct current (125 V dc). DC power returns to JPDF via the same JZ2 and JZ3 connectors, where it is combined with battery power if present.
