Product Description

The Siemens MICROMASTER 440 Variable Frequency Drive (VFD) is designed for precise speed and torque control of 3-phase AC motors, covering a power range from 0.12kW to 250kW (0.16hp to 335hp). Operating at 200-240V (1-phase or 3-phase) or 380-480V (3-phase), it features advanced vector control, optional braking, and high overload capacity (150% for 60s). Suitable for demanding applications like conveyors, pumps, and fans, it offers robust performance with integrated Modbus RTU, USS, and PROFIBUS communication, operating reliably from -10°C to 50°C.

Standard Features

  • Power Range: 0.12-250kW (0.16-335hp) for versatile industrial use

  • Voltage Compatibility: 200-240V (1-phase or 3-phase) or 380-480V (3-phase)

  • Protection: IP20 rating with optional EMC filters

  • Control: Vector control with high dynamic response

  • Overload Capability: 150% for 60s, 100% for 240s in a 300s cycle

  • Communication: Supports Modbus RTU, USS, and PROFIBUS

  • Durability: Operates from -10°C to 50°C ambient temperature
