Features:
- Combines a 125 VDC battery input with as many as two DACA-derived sources.
- Separates protected distribution into three unswitched and six switched branches.
- Returns DC-bus and branch-status information to the PPDA diagnostic module.
IS2020JPDFG01 conditions the battery feed through a 30 A breaker, input filter, series diode, and current-limiting network.
Converter, control-module, trip-board, remote JPDD, and TBCI power paths leave IS2020JPDFG01 through dedicated connector groups.
IS2020JPDFG01 uses a floating DC bus that can be centered to protective earth with jumper JP1.
The General Electric IS2020JPDFG01 DC Power Distribution Module may be available for purchase and support from Apter Power for installed Mark VI or Mark VIe systems.

Battery and DACA Input Paths
- Battery source: A nominal 125 VDC battery feeds the 30 A input breaker.
- AC-derived sources: As many as two DACA modules convert 115 or 230 VAC to 125 VDC.
- Source combining: The diode network permits the available DC sources to share the bus.
- Input limit: IS2020JPDFG01 must not receive more than 145 VDC.
Protected Output Groups
- Unswitched group: Three fused branches remain tied to the conditioned DC bus.
- Switched group: Six fused branches are controlled through the distribution switching path.
- Converter feeds: J1R, J1S, and J1T serve the 125-to-28 V converter circuits.
- Module feeds: J7X, J7Y, and J7Z distribute power to control modules.
Power-System Diagnostic Signals
- Bus magnitude: IS2020JPDFG01 reports the level of the DC distribution bus.
- Ground fault: The diagnostic path monitors leakage from the floating bus to earth.
- AC content: Excessive alternating-current content on the DC bus is detected.
- Branch presence: Output-availability signals are returned through P1 and P2 to PPDA.
Cabinet Integration
- Bus reference: JP1 can center the floating DC bus with respect to protective earth.
- Multiple modules: Only one JP1 grounding jumper is closed when two JPDF modules share a system.
- Orientation: IS2020JPDFG01 is base-mounted vertically in the power distribution cabinet.
- Protective earth: The metal module structure includes its own PE connection.
