Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
Where it sits in the control system
The VFD015A23H 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 VFD015A23H
Delta VFD015A23H — 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 VFD015A23H; confirm the installed unit's part number and revision so the replacement matches both electrically and mechanically.
- Control method: V/f, sensorless vector (IEC 61800-2) — Verify it in the project documentation before confirming the order.
- Certifications: CE, UL, cULus — Check this value against the nameplate of the installed unit before ordering.
- Rated operational voltage: 3-phase 400 V AC — Match it to the existing panel and upstream protection.
- Frequency: 50/60 Hz (IEC 61800-2) — Record it with the other nameplate data when sourcing a replacement.

Common questions about VFD015A23H
Q.Which official Delta document defines VFD015A23H?
The official Delta download-centre catalogue search for this model lists VFD015A23H 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=VFD015A23H. Use that document as the authority for ratings and installation conditions before ordering.
Q.Before ordering VFD015A23H, which supply voltage entry should be checked?
The supply voltage entry quoted above is 1-phase 200...240 V / 3-phase 380...480 V AC. Confirm this figure against the unit currently in the panel.
Q.Where can I find the enclosure rating data for VFD015A23H?
It is listed in the specification table for Delta VFD015A23H as IP20 (IEC 60529). Use the value as the reference when sourcing a current-production equivalent.
Q.For VFD015A23H, what does the specification table state about mounting?
The specification table lists mounting = Cabinet / DIN rail for Delta VFD015A23H. Check the revision of the installed unit if the catalog number has been superseded.
Q.Can the VFD015A23H replace the unit currently installed in my panel?
Compare catalog number VFD015A23H and the ratings above with the nameplate of the installed device. A current-production equivalent is selected by function and electrical rating, not by the label alone.
Q.How do I confirm compatibility of VFD015A23H before ordering?
Match the catalog number VFD015A23H and the specification values listed above against the installed unit, then confirm the firmware or hardware revision where a revision-sensitive part is involved.
