Delta Electronics VFD007M43B Variable Frequency Drive

The Delta Electronics VFD007M43B is a 0.75 kW (1 HP) AC variable frequency drive designed to control speed and torque of three-phase induction motors in PLC-controlled systems, using sensorless vector control alongside V/F modulation for precise motor performance. It accepts 460V AC three-phase input and provides 0–460V AC output up to 400 Hz, with RS-485 (Modbus) communication, 150% overload capability for 60 seconds, and protections against overcurrent, overvoltage, undervoltage, overload, and overheating, all housed with forced-air cooling in a panel-mount package. Common applications include pumps, fans, conveyors, ventilation systems, water pumping units, packaging machines, and small production lines, and it is used for replacements, energy-efficiency upgrades, or automation retrofits; compatible common replacements include Delta VFD007M43A, VFD007B43A, and Schneider ATV320U07N4C.
