The ABB IEPAS22 Power Supply Module is an ABB Bailey industrial power supply reference associated with control system maintenance and spare parts procurement. This product listing also covers IEPAS01, IEPAS02, IEPAF02, IEPDS01, IEPDS02, IEPDF01 and IEPDF02. Together, these references represent different AC and DC system or field power hardware categories.
Wuhan Yuli Automation Technology Co., Ltd. supplies industrial automation products for customers maintaining established control systems. Select the exact model required and request confirmation of availability, hardware revision, product condition and delivery terms.
ABB IEPAS22 Power Supply Module Overview
Industrial automation systems require power hardware that matches the electrical and mechanical configuration of the installed equipment. In established ABB Bailey installations, power supply references may identify system-side or field-side functions and different AC or DC supply arrangements.
The eight models offered on this page are grouped for convenient purchasing, but they are not identical products. The IEPAS references are associated with system power, IEPAF02 is listed as AC field power, IEPDS01 and IEPDS02 belong to the DC system power category, and IEPDF01 and IEPDF02 are DC field power references.
IEPAS22 is included as a separate power supply module reference. Customers should not assume that it is a direct replacement for IEPAS01 or IEPAS02 simply because the model names share a common prefix.
When purchasing a replacement, begin with the original nameplate and the equipment documentation. Verify the complete model number, any revision marking, cabinet configuration and electrical requirements before selecting a module.

Functions and Features
IEPAS22 Power Supply Module
The IEPAS22 reference identifies a specific power supply module within the ABB Bailey spare parts range. Its suitability depends on the original equipment and the installed power system configuration.
Buyers should request the exact part number rather than assume that any other IEPAS module will perform the same function. The original label and control cabinet documentation provide important identification information.
IEPAS01 and IEPAS02 AC System Power
IEPAS01 and IEPAS02 are associated with AC system power hardware. System power modules support the power arrangement specified for compatible control system equipment.
Although both references belong to the same category, they have different model numbers. Any differences in electrical characteristics, installation requirements or hardware revisions should be checked against the applicable ABB documentation.
IEPAF02 AC Field Power
IEPAF02 is listed as an AC field power reference. Field power hardware must be selected according to the installed field-side configuration and the requirements of connected equipment.
Field power and system power are distinct categories. Therefore, IEPAF02 should not be selected as a substitute for an IEPAS system power module without an approved engineering assessment.
IEPDS01 and IEPDS02 DC System Power
IEPDS01 and IEPDS02 are associated with DC system power. They should be identified by their complete model numbers when preparing maintenance requests or spare parts inventories.
The term DC system power does not establish a specific input voltage, output voltage or power rating. These details must be obtained from the applicable manufacturer documentation for the exact reference.
IEPDF01 and IEPDF02 DC Field Power
IEPDF01 and IEPDF02 are listed as DC field power references. Their applications differ from DC system power hardware, even though both categories involve DC power.
When replacing a field power module, confirm the installed model, connected field equipment and any revision requirements. Similar appearances or related model names do not establish interchangeability.
Maintenance and Spare Parts Planning
Industrial control systems often remain operational for many years. As a result, maintenance teams may need to source older power modules for an established installation rather than redesign the complete power system.
Accurate model identification helps reduce purchasing errors. Record the original part number, quantity, revision information and required delivery date before submitting an inquiry.
Industrial Applications
These ABB Bailey power hardware references may be relevant to maintenance projects involving compatible industrial control systems. Typical industries that maintain established automation infrastructure include:
- Power Generation: Control cabinet maintenance and spare parts procurement.
- Oil and Gas: Replacement planning for installed automation equipment.
- Chemical Processing: Maintenance of system and field power hardware.
- Pulp and Paper: Spare parts support for established control systems.
- Water and Utilities: Replacement of approved power components.
- Industrial Manufacturing: Control system refurbishment and maintenance inventory.
These are general industry examples, not guarantees of compatibility. The exact product must match the installed system and manufacturer-approved configuration.
Model Selection and Purchasing Guide
Step 1: Identify the Existing Power Module
Check the nameplate and original spare parts list. Confirm whether the required reference is IEPAS22, IEPAS01, IEPAS02, IEPAF02, IEPDS01, IEPDS02, IEPDF01 or IEPDF02.
Step 2: Confirm the Power Category
Determine whether the installation requires AC system power, AC field power, DC system power or DC field power. These functions must be considered separately during replacement planning.
Step 3: Review Electrical Requirements
Consult the applicable system manual for input requirements, output ratings, connections and protection arrangements. Do not select a module using only the general AC or DC category.
Step 4: Verify Hardware Revision
Compare the original module label with the requested replacement. Where the manufacturer identifies different revisions or replacement references, obtain confirmation before ordering.
Step 5: Request a Model-Specific Quotation
Send the complete model number, required quantity, destination country and preferred delivery schedule. A clear photograph of the original nameplate can help clarify the requested component.
