ACS550-01-012A-4 ABB Original Low Voltage AC Drive 5.5kW 11.9A VFD Frequency Inverter 380-480V Motor Speed Control
The ABB ACS550-01-012A-4 is an original low voltage AC drive from the globally recognized ACS550 general-purpose series, delivering 5.5kW rated power at 11.9A continuous output current for three-phase 380-480V induction motor applications. Designed for both variable-torque loads such as pumps and fans and constant-torque loads including conveyors and mixers, this VFD inverter provides reliable open-loop scalar and sensorless vector speed regulation.
Equipped as standard with an integrated EMC filter, dual DC choke for harmonic suppression, built-in Modbus RTU communication interface, and an assistant control panel with startup wizards, the ACS550-01-012A-4 minimizes commissioning effort and eliminates the need for external filtering components.Installing a genuine ABB ACS550-01-012A-4 replaces degraded power modules and faulty control boards, restoring stable motor acceleration, accurate speed holding, and energy-saving performance without parameter reconfiguration.

FAQ
Q1: What motor power does the ABB ACS550-01-012A-4 drive?
A: It controls three-phase 380-480V induction motors up to 5.5kW (normal duty) or 4kW (heavy duty).
Q2: Does the ACS550-01-012A-4 require an external EMC filter?
A: No. A Category C3 EMC filter and dual DC choke are integrated as standard, reducing installation cost and panel space.
Q3: Is the ABB ACS550-01-012A-4 supplied as an original unit?
A: Yes. We provide genuine ABB original drives, factory-tested for output waveform, insulation resistance, and Modbus communication integrity.
