ABB IEPAS02 AC System Power Supply Module

ABB IEPAS02 AC System Power Supply Module

Functional Description

The IEPAS02 System Power Module converts the 120/240 VAC at the MMU backplane to a primary voltage

of 325 VDC nominal. The DC-to-DC converters convert the primary voltage to secondary regulated voltages

of +5, +15, -15 and +24 VDC.

These voltages travel through the system power bus bar to other module mounting units for distribution to

process control modules. The power modules can be inserted or removed from their mounting unit while

under power.
