Schneider Electric 1/2HP Variable Frequency Drive

The Schneider Electric ATV12H037F1 is a compact variable frequency drive built for single-phase 115V supplies. It suits machine builders and maintenance teams who need three-phase motor control from a standard single-phase source. The NEMA 1 enclosure fits indoor panel installations without additional protection.

2.4A output with 0.5 to 400Hz range

Maximum output current reaches 2.4A, delivering up to 1/2HP at 115V input or 20HP at 200-240V three-phase output. The wide frequency span covers slow-speed positioning through to high-speed spindle work. Headroom ends at the 2.4A limit, so motors drawing more current need a larger drive.

Single-phase in, three-phase out wiring

Input accepts 100-120V AC at 50/60Hz on a single phase, simplifying site power requirements. Output provides 200-240V three-phase power to the motor, removing the need for a separate phase converter. The 7.500 length dimension determines panel space, while the NEMA 1 rating means the cabinet must stay clean and dry.

Questions about this item

Will the ATV12H037F1 drive a 200-240V three-phase motor from my existing 115V single-phase supply?

Yes, the drive accepts 100-120V AC single-phase input and delivers 200-240V AC three-phase output at up to 2.4 A.

How can I confirm the ATV12H037F1 is operating correctly after installation?

Verify the output voltage reads 200-240V three-phase, the output frequency is adjustable between .5 and 400 Hz, and the motor runs at the commanded speed without fault codes.

Does the ATV12H037F1 ship with a mounting bracket or operator keypad, or must I order them separately?

The supplied unit is the drive itself in a NEMA 1 enclosure; mounting hardware and a remote keypad are optional accessories not included in the box.
