Emerson IC695PSA040K PACSystems RX3i 40 W Universal Backplane Power Supply
A two-slot RX3i power supply accepting wide-range AC or DC input and delivering up to 40 W to the universal backplane.
Product Overview
IC695PSA040K is the K hardware release of the IC695PSA040 universal-backplane power supply. The suffix is retained as an identity control; no unverified K-specific capability is inferred.
Emerson specifies nominal 120/240 VAC or 125 VDC input, 40 W total output and two occupied backplane slots. The supply does not support load sharing or redundancy.
A replacement decision must use a complete backplane load calculation and confirm input protection, conductor condition, grounding and the physical rack arrangement.
Performance
Feed the RX3i backplane
Converts the documented AC or DC source into backplane power for supported RX3i modules.
Report supply condition
Uses LEDs for power, power-supply fault, overload and overtemperature status.
Protect the assembly
Provides the documented input-to-backplane isolation within the approved installation.

System Integration
Calculate the load
List every installed module and confirm the complete backplane demand against the 40 W capacity.
Isolate the source
Apply the approved electrical isolation procedure and verify conductors before handling.
Fit and wire
Preserve the two-slot arrangement, grounding, branch protection and one-conductor terminal rule.
Energize and prove
Check all status LEDs, backplane health, controller startup and thermal stability.
Applications
RX3i rack supply
Powering a universal backplane within the published 40 W budget.
Legacy rack maintenance
Replacing the exact K release under an approved module and wiring record.
Panel verification
Confirming source range, protection, grounding and thermal conditions before return to service.
FAQ
Q01Can IC695PSA040K be operated in a redundant load-sharing pair?+
No. Emerson states that load sharing and redundancy are not supported for the IC695PSA040 base supply.
Q02What load evidence should accompany a IC695PSA040K enquiry?+
Provide the full rack module list, calculated backplane demand, source voltage, branch protection and existing supply label.
Q03How much rack space does IC695PSA040K require?+
The power supply occupies two slots in the RX3i universal backplane.
Q04What wiring detail is easy to overlook on IC695PSA040K?+
Emerson specifies 14–22 AWG wiring and one conductor per terminal.
Q05What acceptance checks belong to IC695PSA040K?+
Verify source voltage, grounding, all status LEDs, controller startup, backplane diagnostics and stable temperature under load.
