Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
Where it sits in the control system
The VFD022EL23A 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 VFD022EL23A
Delta VFD022EL23A — 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 VFD022EL23A; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
- Supply voltage: 1-phase 200...240 V / 3-phase 380...480 V AC — Verify it in the project documentation before confirming the order.
- Frequency: 50/60 Hz — Check this value against the nameplate of the installed unit before ordering.
- Operating temperature: 0...+40 °C (IEC 60068-2-1) — Match it to the existing panel and upstream protection.
- Certifications: CE, UL, cULus — Record it with the other nameplate data when sourcing a replacement.
Available from stock with datasheet, certificates and a quotation on request.
Common questions about VFD022EL23A
Q.Which official Delta document defines VFD022EL23A?
The official Delta download-centre catalogue search for this model lists VFD022EL23A 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=VFD022EL23A. Use that document as the authority for ratings and installation conditions before ordering.
Q.For VFD022EL23A, what does the specification table state about supply voltage?
The specification table lists supply voltage = 1-phase 200...240 V / 3-phase 380...480 V AC for Delta VFD022EL23A. Check the revision of the installed unit if the catalog number has been superseded.
Q.Which value is published under rated operational voltage for catalog number VFD022EL23A?
For VFD022EL23A, rated operational voltage is given as 3-phase 400 V AC. Compare it with the nameplate of the installed unit before ordering.
Q.Before ordering VFD022EL23A, which operating temperature entry should be checked?
The operating temperature entry quoted above is 0...+40 °C (IEC 60068-2-1). Confirm this figure against the unit currently in the panel.
Q.Can the VFD022EL23A replace the unit currently installed in my panel?
Compare catalog number VFD022EL23A 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.What should I include in an enquiry for VFD022EL23A?
Send the full catalog number VFD022EL23A, the required quantity and a photo of the nameplate. Stock, lead time and the applicable compliance documents can then be confirmed for Delta VFD022EL23A.
