ABB ACH550 drives for HVAC make maintaining a building’s comfort zone easy, quick and energy efficient. The drives control the speed of pump, fan and compressor motors used in air handling units, cooling towers, chillers and other heating, ventilation and air conditioning (HVAC) applications. They help reduce the HVAC system’s energy consumption by up to 70 percent, and quite often have payback times of less than a year.

The ABB ACH550 is a complete dedicated low voltage AC drive especially for HVAC applications. The drives are designed to meet the HVAC market requirements including harmonics and EMC standards, and for easy integration with building management systems straight out of the box.

They feature built-in control programs specifically designed for HVAC applications like cooling tower fans, supply and return fans, and booster pumps and condensers. With built-in PID control, native BACnet communication, timers, real-time clock and a calendar, ABB drives provide flexible solutions for a wide range of HVAC needs.

Range offering

ACH550-01 for wall-mounted HVAC applications from 0.75 to 160 kW

ACH550-02 for floor mounted HVAC applications from 200 to 355kW

ACH550 keeps you out of trouble and makes operation simple

– with EMC filters for building sector, class C2 (1st  environment).

– by exceeding mandatory harmonic current standard EN 61000-3-12.

-coating electronic boards improve reliability and extend the life-time of the drive.

– operating at temperature up to 50?C without derating.

Override

Override can be used, for example, during a fire for extracting fumes rapidly and efficiently from a building. When override is activated the drive operates in a predefined direction at a pre-set speed while ignoring the drive’s other control commands and internal protective functions.

Real-time clock and calendar

The built-in real-time clock and calendar function provides true time and date stamps to drive events and enables the use of timers. Information is displayed clearly on the control panel. Further, daylight saving times can be easily selected according to different time zones.

Built-in timers

External timer circuits are no longer needed. Built-in timers – utilizing the real-time clock – allow starting and stopping the drive or changing the speed, according to the time of day or night. Relay outputs can be operated with timers to control any auxiliary equipment on site.
