Schneider Electric ATV31HQ37M2 Variable Frequency Drive

Telemecanique Altivar 31 ATV31H037M2 variable frequency drive delivers 0.37 kW (0.5 HP) of motor rating and regulates speed and torque for three-phase asynchronous motors in industrial applications, with input 200–240 V AC single-phase and output 200–240 V AC three-phase. It provides up to 3.3 A output current (4.4 A at 240 V / 5.3 A at 200 V input), 50/60 Hz supply, and 0.5–500 Hz output frequency, and uses sensorless flux vector control with PWM and an adjustable switching frequency from 2 to 16 kHz. An integrated EMC filter, IP20 protection, and panel-mount with heat sink support reliable operation in conveyors, pumps, fans, packaging equipment, textile machinery, and light industrial automation systems. For retrofits or replacements, common alternatives include ATV312H037M2, ATV320U04M2C, and Siemens SINAMICS V20 6SL3210-5BB12-5UV1.
