Schneider Electric ATV31HU15N4 Variable Frequency Drive

Schneider Electric ATV31HU15N4 Altivar 31 variable frequency drive delivers precise speed control for 1.5 kW (2 HP) three-phase motors in industrial lines. It accepts 380–500 V AC three-phase input and provides 380–500 V AC three-phase output, with an output frequency range of 0.5–500 Hz and sensorless flux vector control with PWM, plus an adjustable switching frequency of 2–16 kHz for smooth starts and efficient operation. An integrated EMC filter, IP20 protection, and panel-mount with heat sink simplify installation in conveyors, centrifugal pumps, ventilation equipment, mixers, packaging machines, and other manufacturing lines that require reliable motor speed control. Common replacements include Schneider Electric ATV320U15N4C and ATV340U15N4, along with Siemens SINAMICS V20 6SL3210-5BE21-5CV0.
