Emerson IC695PSD040H RX3i 40 W DC Power Supply
A single-slot RX3i universal-backplane supply with the exact H revision retained.
Overview
IC695PSD040H is the H hardware revision of the IC695PSD040 power supply for PACSystems RX3i universal backplanes. The base supply accepts 24 VDC nominal input and provides a total 40 W to the backplane loads while occupying one slot.
The IC695PSD040 design does not provide input-to-backplane isolation, load sharing or redundancy. The complete IC695PSD040H label must therefore be matched with the installed revision, wiring and calculated rack load.

Features
Forty-watt backplane capacity in a one-slot RX3i supply.
18 to 30 VDC operating input range around the 24 VDC nominal source.
Dedicated LEDs for power, supply fault, overload and overtemperature.
H revision remains part of the purchasing and asset record.
Applications
- Main power supply for a documented RX3i universal-backplane rack.
- One-slot DC supply where the calculated total load remains within 40 W.
- Like-for-like replacement of an installed IC695PSD040H.
Lifecycle
- Calculate the complete rack power demand and compare it with the 40 W total before ordering.
- Record the H label, slot, input polarity, conductor size, protective device and supply voltage.
- Do not plan load sharing or redundant operation with IC695PSD040H.
- After exchange, verify input voltage, all four LED indications, rack diagnostics and stable operation at the actual load.
FAQ
Can IC695PSD040H be used as a redundant or load-sharing power supply?
No. The base IC695PSD040 is specified without load-sharing or redundancy capability.
What information is needed before ordering IC695PSD040H?
Provide the H label, backplane type, slot, 24 VDC source data and a calculated load list for every installed module.
Why can IC695PSD040H report overload even when the input voltage is correct?
The backplane demand or inrush may exceed the 40 W capacity, or a downstream module may be faulty; the rack load must be isolated systematically.
What wiring check is essential for IC695PSD040H?
Confirm polarity, 18–30 VDC at the terminals under load, conductor size, one wire per terminal and the upstream protective device.
What constitutes an IC695PSD040H acceptance test?
Record supply voltage under load, Power/Fault/Overload/Overtemperature LEDs, controller diagnostics and stable operation of the complete rack.
