Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
Where it sits in the control system
The VFD2A7MS43AFSAA is the drive element in a Delta motor installation. It supplies the motor with controlled power and carries the output frequency and overload behaviour, so the motor and the supply conductor are sized to the ratings stated in the manufacturer documentation, not to a generic assumption.
Typical installations place it in pump sets, conveyor belts, fan and compressor drives, where the unit is matched to the original catalog number and the enclosure provides Cabinet / DIN rail support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Selection notes for Delta VFD2A7MS43AFSAA
Delta VFD2A7MS43AFSAA — Variable frequency drive for motor speed and torque control in pumps, fans, conveyors and general industrial machinery. The figures below are taken from the specification table on this page for catalog number VFD2A7MS43AFSAA; confirm the installed unit's part number and revision so the replacement matches both electrically and mechanically.
- Enclosure rating: IP20 (IEC 60529) — Use it as the reference when cross-checking a current-production equivalent.
- Certifications: CE, UL, cULus — Verify it in the project documentation before confirming the order.
- Rated operational voltage: 3-phase 400 V AC — Check this value against the nameplate of the installed unit before ordering.
- Supply voltage: 1-phase 200...240 V / 3-phase 380...480 V AC — Match it to the existing panel and upstream protection.
For a discontinued unit, match function and electrical ratings rather than the label alone.
Common questions about VFD2A7MS43AFSAA
Q.Which official Delta document defines VFD2A7MS43AFSAA?
The official Delta download-centre catalogue search for this model lists VFD2A7MS43AFSAA under the Delta product line, and the product type published for this catalog number is "VFD Drive". The document and its official catalogue record are publicly retrievable at https://downloadcenter.deltaww.com/en-US/DownloadCenter?q=VFD2A7MS43AFSAA. Use that document as the authority for ratings and installation conditions before ordering.
Q.For VFD2A7MS43AFSAA, what does the specification table state about supply voltage?
