Overview

Product Introduction

IEPAS02 is the AC-input power module used in the ABB Bailey AC Modular Power System. It accepts 120 or 240 VAC and supplies the regulated +5, +15, −15 and +24 VDC buses used by the cabinet power architecture.

The module is rated for 130 W maximum output and one mounting slot. ABB documents compatible operation with the earlier IEPAS01 and IEPAF01 modules in the same cabinet, subject to the system loading, redundancy and power-entry design.

System fit

Compatibility & Power-System Evolution

01

ABB states that IEPAS02 replaces IEPAS01 and is compatible with IEPAS01 and IEPAF01 in the same cabinet.

02

The AC Modular Power System supports N+1 power-module arrangements when cabinet load and installed hardware are engineered accordingly.

03

ABB evolution planning literature treats migration from the older Modular Power System as a system-level project toward MPS III. It is not a drop-in part substitution and requires cabinet, bus, loading and lifecycle planning.

04

Maintenance context

Applications & Fault Scenarios

Cabinet bus alarm

One or more regulated DC buses fall outside the expected range and the load, module status and power-entry path must be separated.

Loss of redundancy

The cabinet continues operating after one module fails but no longer has the intended N+1 margin.

Input transfer disturbance

A line event or source transfer causes resets, leading to checks of input range, hold-up, loading and power-entry operation.

Thermal loading

A fully loaded cabinet runs near its ambient limit and power-module heat plus airflow needs review.

05

Field practice

Load Planning, Redundancy & Service Safety

Calculate every DC bus

Use the installed module loads for +5, +15, −15 and +24 VDC. Maximum total wattage alone is not enough; each bus and the cabinet redundancy target must remain within the power-system design.

Confirm source selection

Verify the 120/240 VAC configuration, input protection and power-entry wiring before service. Record the normal and alternate sources where redundant feeds are installed.

Restore N+1 promptly

A cabinet may remain online after one module loss, but the redundant margin is gone. Treat replacement as a reliability action and investigate any concurrent bus alarm.

Use qualified power procedures

The manufacturer system supports module service features, but live power work is hazardous. Only trained personnel following ABB and site electrical-safety procedures should perform it.

Product-specific answers

FAQ

Which DC buses are supplied by IEPAS02?

The AC Modular Power System provides regulated +5, +15, −15 and +24 VDC buses for cabinet modules.

Can IEPAS02 replace IEPAS01?

Yes. The manufacturer instruction states that it replaces IEPAS01 and can coexist with IEPAS01 and IEPAF01 in the same cabinet.

What AC input ranges are specified for IEPAS02?

The documented ranges are 90–132 VAC for 120 V nominal service and 180–264 VAC for 240 V nominal service at 47–63 Hz.

How should IEPAS02 capacity be checked?

Calculate the load on each regulated bus and total cabinet power, then confirm the required N+1 margin. Do not size the system from the 130 W total alone.

Can IEPAS02 be serviced with the cabinet energized?

The original system documentation describes service features, but energized work is hazardous. Only qualified personnel following ABB and site procedures should decide and perform it.

What details should an IEPAS02 RFQ include?

Provide the input voltage, installed power-module mix, cabinet or MMU type, quantity, destination, required date and system model.
