Emerson IC695PSA140J PACSystems RX3i Multi-Purpose Power Supply
A 40 W, two-slot RX3i Universal Backplane supply for single, increased-capacity or redundant architectures.
Product Identification
IC695PSA140J is the revision-J execution of the PACSystems RX3i 40 W multi-purpose supply. It accepts 85 to 264 VAC or 100 to 300 VDC and installs only in an IC695 Universal Backplane.
Unlike the PSA040 standard supply, the PSA140 supports load sharing and redundancy. One unit can serve as the sole rack supply, or a documented multi-supply design can provide greater capacity or redundancy within the manufacturer rules.
Engineering Data
Functions
Flexible supply architecture
Supports standalone use as well as engineered load-sharing and redundant arrangements.
Wide input acceptance
Operates from common plant AC services or a suitable 125 VDC-class source.
Four-condition indication
Local LEDs distinguish power availability, supply fault, overload and overtemperature states.
Universal Backplane integration
Uses the IC695 backplane for power distribution and controller fault reporting.

Applications
Redundant RX3i power
Pairing supplies under an approved architecture where continued rack power is required after one supply fault.
Increased-capacity rack
Sharing load when a single 40 W unit does not cover the documented module demand.
Single AC/DC source duty
Serving as the only supply where its two-slot footprint and 40 W capacity fit the rack plan.
Lifecycle
Define the mode
Record whether the rack is single-supply, increased-capacity or redundant and capture all participating part numbers.
Verify installation
Check input source, two-slot placement, conductor size, grounding and load-sharing wiring.
Test the design
Confirm normal indicators and execute the approved overload, fault or redundancy proof appropriate to the rack architecture.
FAQ
Q01
Can IC695PSA140J be used for RX3i redundant power?
+
Yes, the PSA140 supports redundancy, but the complete multi-supply arrangement and rack load must follow the manufacturer design rules.
Q02
How does IC695PSA140J differ from IC695PSA040?
+
IC695PSA140J is the multi-purpose version with load-sharing and redundancy support; the PSA040 is not a direct architectural equivalent.
Q03
What should accompany an IC695PSA140J quotation request?
+
Send the J revision label, Universal Backplane model, supply positions, input source, complete module list and calculated 40 W load budget.
Q04
Which IC695PSA140J indicators should be checked during commissioning?
+
Verify Power, P/S Fault, Overload and Overtemperature states under the approved operating and test conditions.
Q05
What proves a redundant IC695PSA140J installation is ready?
+
Normal load sharing, correct diagnostic status and a controlled proof that the rack remains powered after the approved single-supply isolation establish acceptance.
