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