The ACH550 is an variable frequency AC drive designed specifically for the HVAC market that achieves the ultimate in flexible motor control performance. Offering two modes of motor control: Scalar (V/Hz) and Sensorless Vector, the ACH550 provides
accurate speed control for any standard squirrel cage motor.
With drives ranging from 1 to 550 HP, the ACH550 series features an ‘intuitively obvious’ multi-lingual, graphic display panel that also provides an assistant to aid users in start-up. The control panel can be mounted on the cover of the drive, or remotely, and
can upload, store, and download parameters.
The ACH550 comes equipped with an extensive library of preprogrammed HVAC application macros that, at the touch of a button, allow rapid configuration of inputs, outputs, and parameters for specific HVAC applications to maximize convenience and
minimize start-up time.
The ACH550 can be used for the simplest to the most demanding HVAC applications. Two internal option slots can be configured with additional relay outputs as well as a host of different communication bus adapters.
The ACH550 has a 110% short term overload rating for one (1) minute out of ten (10) and is capable of >130% short-term overload rating for 2 seconds out of each minute. This provides the torque you need to start high inertia fan(s).
