£2,956.00
The ABB ACH480-04-050A-4 (Part Number 3AXD50000275755) is a compact and reliable AC variable frequency drive (VFD) module designed specifically for HVAC motor control applications. As part of the ABB ACH480 HVAC drive series, it provides efficient speed and torque control for fans, pumps, compressors and air-handling equipment in commercial and industrial building systems.
This cabinet-optimised HVAC drive module is built to simplify installation, commissioning and everyday operation. With complete HVAC functionality integrated into a compact IP20 format, it helps building services engineers achieve smooth, energy-efficient control of ventilation, pumping and cooling systems.
With a rated output power of 22 kW and a nominal output current of 50 A, the ACH480-04-050A-4 is suitable for medium-sized HVAC motors. The drive operates from a three-phase 380–480 V AC supply and is designed for cabinet or wall-mounted installation.
Variable frequency drives such as the ABB ACH480 regulate motor speed by adjusting the output voltage and frequency supplied to the motor. In HVAC systems, this allows fans, pumps and compressors to operate according to actual demand, improving energy efficiency and reducing mechanical stress.
The ACH480 series is designed for heating, ventilation and air conditioning applications where compact installation, straightforward commissioning and reliable operation are essential. Its HVAC-focused functionality supports smooth control of building services equipment in both standard and critical environments.
