Please note: The ACS550 range has now been replaced by the ACS580.
The ABB ACS550 range from 0.75kW to 355 kW – DriveIT Low Voltage AC Drive. The ABB Standard drive is simple to buy, install, configure and use, saving considerable time. The drive has common user and process interface with fieldbus, common software tools for sizing, commissioning, maintenance and common spare parts.
The ABB standard drive can be used in a wide range of industries. Typical applications include pump, fan and constant torque use, such as conveyors. The ABB standard drive is ideal in those situations where there is a need for simplicity to install, commission and use and where customising or special product engineering is not required.
Key Highlights
- Assistant control panel providing intuitive use of the drive
- Patent pending swinging choke for superior harmonic reduction
- Sensorless vector control
- Integral RFI filter for 1st and 2nd environment as standard
- Flexible fieldbus system with built-in Modbus and numerous internally mountable fieldbus adaptors
- UL, cUL and CE approved
