Siemens 6SE7038-6GL84-1JA1 MASTERDRIVES PSU2
A replacement PSU2 internal power-supply module for SIMOVERT MASTERDRIVES chassis units in design sizes J through M.
Product Profile
6SE7038-6GL84-1JA1 is a Siemens PSU2 power-supply module used as an internal spare in SIMOVERT MASTERDRIVES devices of designs J through M. It supplies the assigned internal electronics within the matching converter architecture.
This article is a legacy service spare and must be matched to the complete converter nameplate and physical design size. It is not a general-purpose DIN-rail power supply.

System Role
- Provides the documented PSU2 internal power-supply function.
- Supports control and interface electronics inside compatible MASTERDRIVES chassis units.
- Restores the assigned board position after the upstream and downstream circuits have been checked.
- Depends on the host converter input power, wiring, cooling and protective circuits.
Compatibility
- Use only with documented MASTERDRIVES devices in designs J through M.
- Confirm the converter MLFB, design size, installed board code and connector arrangement.
- Do not substitute another PSU board solely because the mechanical outline looks similar.
- Review fuses, auxiliary rails and connected boards before energizing a replacement.
Applications
- Repair of compatible MASTERDRIVES chassis units in design sizes J through M.
- Legacy drive spare planning for an identified installed base.
- Controlled refurbishment after the PSU2 module has been diagnosed as the failed assembly.
FAQ
Which evidence confirms that 6SE7038-6GL84-1JA1 fits an installed converter?
Provide the full MASTERDRIVES MLFB, design size J through M, existing PSU2 label, connector photographs and board position.
Can 6SE7038-6GL84-1JA1 be used as a stand-alone cabinet power supply?
No. 6SE7038-6GL84-1JA1 is an internal MASTERDRIVES service module whose inputs, outputs and protection are defined by the host converter.
What should be checked before replacing 6SE7038-6GL84-1JA1?
Test upstream supply and fuses, inspect downstream boards for shorts, review auxiliary-rail symptoms and confirm cooling and contamination conditions.
Which safety controls apply to an 6SE7038-6GL84-1JA1 exchange?
Isolate all converter supplies, observe the specified discharge time, prove absence of voltage and use grounded ESD procedures.
What is a useful acceptance test after fitting 6SE7038-6GL84-1JA1?
Verify stable auxiliary rails and diagnostics first, then test the converter at controlled conditions while monitoring temperature, faults and connected electronics.
