Siemens 6SE7027-2TD84-6HF3 PEU4 Power Section Board
A coated PEU4 service board for the 72 A, 510–620 V DC SIMOVERT MASTERDRIVES inverter class.
Technical Summary
6SE7027-2TD84-6HF3 is a PEU4 power-section board for a legacy SIMOVERT MASTERDRIVES inverter in the 72 A, 510–620 V DC class. The complete suffix identifies a coated service-board configuration and must remain attached to the host drive record.
This is a board-level service item, not a complete converter. Connector layout, power-section hardware, board revision and the full host nameplate must agree before installation.

- Compare board barcode, connector keying, coating and installed power-section position.
- Verify the DC-link class, current class and cooling arrangement of the host assembly.
- Do not substitute another PEU board based on physical similarity.
Replacement
- Back up accessible parameters and diagnostic history before isolation.
- Observe the specified DC-link discharge procedure and use ESD protection.
- Photograph all connectors, then complete controlled energization and drive testing.
FAQ
Is 6SE7027-2TD84-6HF3 a complete SIMOVERT drive?
No. It is a PEU4 board used inside the matching power section and must be quoted as a board-level spare.
Can another 6SE7027 board replace 6SE7027-2TD84-6HF3?
Only after the complete suffix, host rating, coating, connectors and hardware revision are confirmed as equivalent.
What nameplate data should be sent for 6SE7027-2TD84-6HF3?
Provide the full drive order number, board barcode, power-section label, serial context and clear connector photographs.
Why does the coated construction matter for 6SE7027-2TD84-6HF3?
Coating is part of the specified board configuration and should not be changed without an approved service decision.
What safety preparation is required before handling 6SE7027-2TD84-6HF3?
Isolate all supplies, observe the documented discharge time, prove absence of voltage and apply ESD controls.
What tests follow installation of 6SE7027-2TD84-6HF3?
Complete visual checks, insulation and power-stage review, controlled energization, diagnostics and machine functional testing.
