ACS550-01-012A-4 ABB Variable Frequency Inverter -40 °C To 85 °C 18.5 / 22kw

ACS550-01-012A-4 Description

The ACS550-01-012A-4 is a compact, general-purpose three-phase AC variable frequency drive designed for speed and torque control of induction motors. It operates from a 380–480 V AC three-phase supply with a rated output current of 12 A, suitable for driving 5.5 kW (Normal Duty) and 4 kW (Heavy Duty) motors. Equipped with direct torque control (DTC), built-in protection, and standard communication interfaces, it provides stable, energy-efficient operation for pumps, fans, conveyors, and small industrial machines.

ACS550-01-012A-4 Key Features

  • Advanced DTC (Direct Torque Control) and scalar V/f control for high dynamic performance
  • Dual rating: 5.5 kW ND / 4 kW HD, flexible for various load types
  • Built-in RS485 Modbus RTU for easy PLC and system integration
  • Integrated braking chopper for fast deceleration control
  • Built-in EMC filter to reduce electromagnetic interference
  • Comprehensive protection: overcurrent, overvoltage, undervoltage, overtemperature, motor overload
  • User-friendly control panel for parameter setting, monitoring and fault diagnosis
  • Robust construction suitable for continuous industrial operation
  • Compact wall-mounted design for easy cabinet installation

ACS550-01-012A-4 Materials & Applications

Materials

  • Housing: Cold-rolled steel with powder coating, high mechanical strength and corrosion resistance
  • Power module: High-performance IGBT power switches with low loss
  • Heat sink: Extruded aluminum alloy for efficient heat dissipation
  • Cooling: Long-life DC fan for forced air cooling
  • PCB: Industrial-grade FR-4 circuit board with stable anti-interference performance
  • Terminals: Nickel-plated copper screw terminals, high current capacity and vibration resistance

Typical Applications

  • Pumps, fans, blowers (HVAC, water supply, wastewater treatment)
  • Conveyors, belt drives, material handling equipment
  • Small mixers, agitators, compressors
  • Packaging machines, textile machines
  • General small automation machinery
  • Machine tool auxiliary axes
