Schneider Electric ATV12H055M2 Drive

The Schneider Electric ATV12H055M2 is a variable frequency drive rated for three-quarter horsepower at 230 volts AC. It accepts single-phase input between 200 and 240 volts at 50 or 60 hertz and delivers three-phase output across the same voltage range. The unit suits motor-control tasks in light industrial and building-automation settings. Its NEMA 1 enclosure fits standard indoor mounting.

Continuous operation at 3.5 A output

Under sustained load the drive supplies up to 3.5 amperes of output current across a frequency range of 0.5 to 400 hertz. Thermal management is handled by the enclosed chassis without external cooling accessories. The single-to-three-phase conversion maintains steady torque for conveyors, fans and pumps running extended duty cycles. Protection features respond to overcurrent and overtemperature conditions.

Replaces fixed-speed starters for variable torque

This drive replaces direct-on-line or soft-starter arrangements where motor speed must vary with process demand. The upgrade is worthwhile when energy savings from reduced flow or pressure outweigh the installed cost. It does not suit applications requiring multi-motor coordination or regenerative braking. Buyers needing higher horsepower or NEMA 4X protection should select a larger frame.

Questions about this item

How much heat does the ATV12H055M2 produce when running at 3.5 A output all day?

The drive delivers up to 3.5 A at 200-240 V AC three-phase output; heat dissipation scales with load and ambient temperature, so ensure the NEMA 1 enclosure has adequate ventilation for continuous operation.

What supply wiring and protection must I already have to install this 3/4 hp drive?

Provide a 200-240 V AC single-phase source at 50/60 Hz with a suitable branch-circuit breaker and conductors rated for the drive's input current; the unit itself has no internal disconnect.

Will the 0.5-400 Hz output range work with a 50 Hz motor I already own?

Yes, the output frequency covers 0.5 to 400 Hz, so a standard 50 Hz motor can be run at its rated speed and also slowed down or sped up within the drive's range.
