Product details

The Delta VFD037M21A is a VFD-M series micro drive rated for 3.7 kW (5 HP) motor capacity on a 230V single-phase supply. Its 10 A continuous output and 3.8 kVA capacity mean it handles a standard 3.7 kW induction motor at full load without derating — sized for pumps, fans, and light conveyors in a 200–240 VAC line. The 0.1–400 Hz output range with 1–15 kHz carrier frequency gives you headroom for high-speed spindle applications or quiet operation at lower carrier settings.

Input power configuration — single-phase feed, three-phase motor

This drive accepts single-phase 200–240 VAC input (rated 11.5 A single-phase, 7.6 A when fed from a three-phase source). The input current for 1-phase models when using 3-phase power is 27 A — that's the inrush or transient figure, not the continuous draw. Voltage tolerance is ±10% (180–264 VAC), frequency tolerance ±5% (47–63 Hz). Fan-cooled, so ensure clearance around the heatsink fins in the panel.

Frequently asked questions

What is the closest functional second-source to VFD037M21A?

The VFD110B23B is a peer in the same VFD series but a different version (B vs A) and takes three-phase 230V input rather than single-phase. It is not a direct electrical swap without rewiring the supply.

How do I get current pricing and availability for VFD037M21A?

Sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will VFD037M21A drop into a panel specified around VFD110B23B without rewiring?

No — VFD110B23B requires three-phase 230V input, while VFD037M21A runs on single-phase 230V. The power wiring differs; the mechanical footprint may match, but the supply circuit must be reconfigured.

What compliance documentation does Delta provide for VFD037M21A?

The VFD-M series carries CE marking as standard. Specific RoHS, REACH, and UL documentation is available on request — confirm at order time for your jurisdiction.
