2.2 kW at 240 V single-phase in a Frame C footprint
The Delta VFD11AMH21ANSAA is a 1-phase 200–240 V variable-speed drive in the M-Series compact frame, rated to drive a 2.2 kW / 3 HP motor at 12.5 A continuous output (cite:,). That rating fixes the application slot: small conveyors, fans, pumps and small mixers where single-phase mains is all the panel has, and the motor frame is IEC 90 or NEMA 143/145. Frame C keeps the panel footprint tight enough to sit next to a breaker column in a 300 mm-deep enclosure, and the natural-cooling design means no fan filter to clean on the washdown-adjacent lines where IP20 is the panel-side barrier, not the cabinet-side (cite:,).
Duty ratings — heavy vs normal actually decides the fit
Two published current numbers sit on the same nameplate: 24.2 A heavy-duty input and 27.5 A normal-duty input, which gate the upstream breaker or fuse selection (cite:,). Picking normal duty is how Delta stretches the drive to a slightly larger motor for variable-torque loads like fans and centrifugal pumps; heavy duty is the conservative call for constant-torque conveyors, hoists and extruders where stall torque matters. Carrier frequency defaults to 4 kHz and can be raised to 15 kHz — the higher kHz quiets motor whine but pushes additional switching loss into the IGBTs, so a derating on continuous output is the expected trade-off the installer should plan for (cite:).
Sourcing posture and lifecycle read
The listed lifecycle stage is current production, with an estimated lead time of 1–10 working days from the catalog line (cite:,). No official successor or cross-reference appears in the record, so the BOM position stays on this exact order code rather than a re-specified variant — that keeps the spare in the storeroom swappable with anything already wired against the M-Series template.
