Features:
- Forms the P2 backplane for the J2 and J3 portions of the LS2100 VME card cage.
- Provides the rack paths used for internal board interconnection and electronics power.
- Exposes the regulated rails checked during LS2100 control-rack startup.
DS200VPBLG1A belongs to the printed-wiring-board set documented for GE LS2100 installation and startup.
The J2 area supports control and interface boards, while J3 is reserved for connections that cannot be placed on the board fronts.
Startup checks confirm +5 V, +15 V, -15 V and +24 V at the backplane before the full rack remains energized.
The General Electric DS200VPBLG1A LS2100 VME P2 Backplane Board may be available for purchase and technical support through Apter Power.

VME P2 Functions
- Rack Position: The VPBL assembly forms the rear P2 connection plane.
- J2 Area: This portion carries the supported LS2100 control-board positions.
- J3 Area: Rear external connections use the section not available on board fronts.
- System Scope: The backplane belongs to the LS2100 LCI control rack.
Control-Rack Supply Checks
- Logic Rail: The +5 V point is verified at the backplane during startup.
- Positive Analog: A regulated +15 V rail is measured at VPBL.
- Negative Analog: The complementary -15 V supply is checked at the same assembly.
- Auxiliary Rail: The backplane also exposes the +24 V electronics supply.
Energization Sequence
- Initial Check: Power rails are measured with the control-rack boards withdrawn.
- Board Insertion: Rack boards are reinserted only after power is removed.
- Loaded Check: The four supply rails are measured again with every board installed.
- Adjustment Point: The electronics supply is trimmed until the VPBL readings meet the LS2100 limits.
LS2100 Control Architecture
- Equipment Type: LS2100 is a load-commutated-inverter static-starter control platform.
- Rack Function: The VME cage groups the digital controller and supporting interface boards.
- Reference Set: VPBL is listed in the LS2100 printed-wiring-board reference.
- Board Manual: GEI-100227 is the dedicated VPBL document identifier.
