Application Scenarios & Pain Points
Aging rack power supplies can create faults that look like failed CPUs or I/O boards. In older industrial computers, unstable voltage rails often show up first as random resets, corrupted memory states, or unexplained communication interruptions.
Typical applications:
- Industrial Automation Racks: Supplies DC power to VME-based controller systems, communication boards, and embedded control electronics.
- Test and Measurement Equipment: Used where multiple DC rails are required for instrumentation and data acquisition hardware.
- Rail and Transportation Systems: Supports rack electronics requiring long service life and stable power conversion.
- Defense and Aerospace Test Systems: Applied in legacy electronic assemblies using modular rack architectures.
Field note: A manufacturing test platform began reporting random controller restarts after years of operation. The processor board passed diagnostics, but voltage measurements showed unstable output from the rack supply. Replacing the MPS022 and checking the backplane load restored normal operation.

The Engineer’s Guide: Field Pitfalls to Avoid
⚠️ Output Voltage Rail Mismatch
Not every rack power supply with a similar appearance provides the same voltage rails.
How to avoid: Verify +5V, +12V, and -12V requirements against the equipment manual before replacement.
⚠️ Ignoring Backplane Load Requirements
A power supply may start correctly but fail under full system load.
How to avoid: Calculate total board current consumption, especially when adding replacement CPU or I/O modules.
⚠️ Connector and Mechanical Compatibility Issues
Rack power modules may share similar dimensions but use different connectors or pin layouts.
How to avoid: Compare connector position, mounting hardware, and keying before installation.
Frequently Asked Questions (FAQ)
What is the main function of the SCHROFF MPS022 13100203?
The MPS022 is an AC/DC rack power supply module providing regulated DC outputs for industrial electronic systems, including VME-based rack applications.
What voltage outputs does the MPS022 provide?
The module provides three DC output rails:
- +5V
- +12V
- -12V
These rails support different electronic boards installed in rack-based systems.
Is the a PLC power supply?
No. It is primarily a rack power module used for industrial electronic systems and embedded control platforms rather than a standard PLC power supply.
Can I replace an with another SCHROFF power module?
Only after checking:
- Output voltage requirements
- Current ratings
- Connector type
- Mechanical dimensions
- Rack compatibility
Why does a system fail after replacing the power module?
Common causes include:
- Incorrect output voltage configuration
- Overloaded power rails
- Loose rack connectors
- Backplane faults
- Cooling problems
What should be checked before purchasing a 13100203?
Recommended checks:
- Exact part number: 13100203
- Existing label information
- Required output voltages
