Delta Electronics VFD007L21A Variable Frequency Drive

The Delta Electronics VFD007L21A AC Drive is a compact 1 HP (0.75 kW) variable frequency drive that powers small three-phase motors from a 220–230V single-phase input, delivering 0–230V AC three-phase output and an adjustable 0–400 Hz output frequency for precise speed control. In PLC-driven motor control systems it regulates speed and torque for fans, pumps, conveyors, and light industrial machinery, making it a common replacement or upgrade for energy-saving projects and automation retrofits in ventilation systems, small conveyors, water pumps, and packaging equipment. Part of the VFD-L Series, this drive provides V/F control with DC injection braking, 150% overload capacity for 60 seconds, and RS-485 (Modbus) communication, along with protection from overcurrent, overvoltage, undervoltage, overload, and overheating. It uses forced air cooling and is designed for panel mounting, with an operating temperature range of −10°C to 50°C.
