The ABB ACS550 is an AC inverter drive that controls the speed of AC induction motors by converting a fixed frequency input to a variable frequency. It's suitable for a range of applications, including pumps, fans, conveyors, and mixers. Here are some of its features:
Control panel
The ACS550 has a multilingual, graphic display panel that can be mounted on the drive or remotely. It also has an assistant to help users get started.
Preprogrammed macros
The ACS550 has a library of preprogrammed macros that can be used to configure inputs, outputs, and parameters for specific applications.
Option slots
The ACS550 has two option slots that can be configured with relay outputs and communication bus adapters.
Brake chopper
All R1 and R2 frame size drives have an integral brake chopper.
Energy efficiency
The ACS550 has counters that show saved energy, carbon dioxide emissions, and cost.
Safety
The ACS550 should only be installed by a qualified electrician. Dangerous voltage is present at the power circuit terminals even when the motor is stopped.
The ACS550 has been replaced by the ACS580.
