Features:
- Routes three converter outputs through identified R, S, and T buses.
- Supplies dedicated controller and downstream distribution connectors.
- Keeps PPDA electronics powered through a three-source diode-OR path.
JPDM is the organizing board between external 28 V converters and the protected loads inside the control cabinet.
Its bus topology can remain fully separated or be joined by external jumpers to suit the documented supply arrangement.
Monitoring enters at the PPDA mounting position and continues through the P1/P2 ribbon chain without combining the individual load feeds.
The General Electric IS200JPDMG1A 28 V DC Power Distribution Board may be available for purchase and support from Apter Power.

Three-Feed Architecture
- Converter inputs: JR, JS, and JT receive the three external 28 V DC feeds.
- Bus identity: R, S, and T remain distinguishable across distribution.
- Controller paths: JCR, JCS, and JCT preserve the same channel assignment.
- Board linking: Two adjacent JPDM assemblies can extend the cabinet bus structure.
Supply Arrangement Choices
- Independent mode: Three converters can operate on three separated buses.
- Common-source mode: External jumpers permit one supply to feed the shared structure.
- Redundant mode: Jumper routing also supports redundant converter inputs.
- Physical control: The selected topology is established by wiring rather than software.
Feedback Power and Data
- Pack position: JA1 accepts the power-distribution diagnostic I/O pack.
- Power resilience: P4 diode-ORs all three DC buses for the PPDA supply.
- Ribbon interface: P1 and P2 connect other boards into the diagnostic chain.
- Bus observation: The hosted pack receives status from the wider PDM assembly.
Protected Output Groups
- Branch feeds: J1, J2, and J3 carry fused power to downstream boards.
- Control feeds: A separate connector set is reserved for controllers.
- Output protection: Every outgoing circuit leaves through board-level fusing.
- Load separation: Branch and controller connectors do not share the same terminal positions.
