Schneider Electric ATV12P037M3 Altivar 12 Variable Speed Drive – 0.37kW, 0.55HP, 200–240V 3-Phase
Schneider Electric ATV12P037M3 Altivar 12 0.37kW / 0.55HP variable speed drive with 200–240V 3-phase input, 2.4A output, Modbus communication and compact base-plate mounting for simple industrial machines.
Description
The Schneider Electric ATV12P037M3 is an Altivar 12 variable speed drive (VSD/VFD) designed to control three-phase asynchronous motors in simple industrial machines and automation applications. It provides 0.37kW (0.55HP) motor power with a 200–240V AC three-phase supply and a three-phase motor output. Schneider Electric specifies this model as the P version with a base plate rather than a standard rear heatsink.
The ATV12P037M3 offers compact, cabinet-friendly installation and is intended for applications where straightforward motor speed control is required. The Altivar 12 platform supports Modbus communication, configurable analog and digital I/O, and motor-control functions including V/f, quadratic V/f and sensorless flux-vector control.
For the 0.37kW three-phase M3 version, the drive has a 2.4A nominal output current, with up to 3.6A for 60 seconds for transient operation. Its output frequency range is 0.5–400Hz, making it suitable for variable-speed applications such as small conveyors, pumps, fans and simple machine drives.
Important: The M3 suffix is specifically for 200–240V three-phase input. Schneider Electric states that ATV12 M3 drives are not rated for single-phase supply; the M2 version is the appropriate ATV12 variant for 200–240V single-phase input.
