Features:
- Divides RX3i backplane demand among compatible supplies in an approved sharing arrangement.
- Maintains redundant power capacity with as many as four supported units.
- Accepts plant AC or DC sources and reports overload and thermal protection states.
IC695PSA140 is selected when one 40 W supply must participate in a shared-load or redundant RX3i power architecture.
The design still requires separate rail calculations, because total wattage does not prove that the 3.3 VDC, 5 VDC, and relay outputs remain within limit.
After one unit is removed or faulted, the remaining supplies and sources must carry the required rack demand under the applicable thermal derating.
General Electric IC695PSA140 PACSystems RX3i 40 W Multipurpose AC/DC Power Supply is available for Apter Power quotation and official-documentation support.

IC695PSA140 Fault and Recovery
- Overload indication: Use the overload LED with the rail calculation to locate excessive backplane demand.
- Thermal trip: Compare enclosure temperature and total load with the derating curve before resetting an overtemperature event.
- Shared system: A faulted unit must be isolated without exceeding the surviving supply capacity.
- Return to service: Restore sharing connections and confirm stable output from every participating supply.
IC695PSA140 Supported Input Sources
- AC operation: Connect the supported 120/240 VAC source with the required line and neutral protection.
- DC operation: For 125 VDC service, preserve terminal polarity and the specified disconnect arrangement.
- Floating neutral: Use the required RX3i floating-neutral connection when the AC neutral is not bonded to ground.
- Source redundancy: Independent feeds must follow the approved redundancy diagram rather than an improvised parallel connection.
IC695PSA140 Sharing Connections
- Compatible units: Only supplies permitted by the RX3i load-sharing diagram may be interconnected.
- Share wiring: Install the designated sharing conductors before energizing the rack.
- Source routing: Keep the input feeds consistent with the selected shared-load or redundant-source architecture.
- Service isolation: De-energize and identify every feed before disconnecting one supply from the group.
IC695PSA140 Capacity Planning
- Rail totals: Calculate 3.3 VDC, 5 VDC, and relay output demand instead of checking only aggregate watts.
- N-plus-one margin: For redundancy, the remaining supplies must carry the full required load after one unit is unavailable.
- Unit count: The approved arrangement supports as many as four compatible supplies when the backplane layout permits.
- Thermal margin: Apply the enclosure-temperature derating to each active unit, including the post-fault load transfer.
