The Delta VFD7A5MH21ANSAA is a single-phase 200–240 V variable-frequency drive rated for a 1.5 kW (2 HP) motor in Frame C, used to run small three-phase loads like a pump, fan, or conveyor motor from a single-phase supply on a plant floor.
Ratings and what they decide on the BOM
Output is 8.5 A at 3.2 KVA, sized to drive a 1.5 kW / 2 HP motor — the heavy-duty input rating is 16.5 A and the normal-duty figure is 18.5 A, so the drive is right-sized for the motor rather than oversized. The input is 1-phase AC 200 V–240 V at 50/60 Hz (operating range 170–265 Vac), with a 2–15 kHz carrier (factory default 4 kHz) — raising the carrier quiets motor whine but derates continuous output current, so the 4 kHz default is the figure to design around. Cooling is natural convection, IP20, with the EMC filter listed as optional — meaning the drive ships without an integrated filter unless specified, and panel-side EMC mitigation (line reactor or external filter) belongs in the design if the installation is mixed with sensitive instrumentation.
Sibling frame and what stays the same
Within the same 1-phase 200–240 V line, the 0.75 kW sibling sits in Frame B and the 2.2 kW sibling shares Frame C — both keep the same cooling, IP20, EMC filter option, and 2–15 kHz carrier behavior, so a panel spec pinned to this drive can scale up or down without changing footprint rules, only the frame and current figures.
