Product description
The ABB ACS550-01-031A-4 is a three-phase frequency converter from the ABB-ACS550 series. ABB assigns the exact version to the 380 to 480 V voltage range and R3 frame. Rated data for normal use is 31 A and 15 kW motor power. For heavy-duty use, the catalog specifies 23 A and 11 kW. Output frequency is specified from 0 to 500 Hz. The ACS550 provides scalar control or sensorless vector control and an integrated PID controller. Standard equipment includes a control panel, built-in line choke, first-environment EMC filter and Modbus communication. The removable alphanumeric panel presents parameters and messages as plain text and supports multiple display languages. Control interfaces comprise two analog inputs, two analog outputs, six digital inputs and three relay outputs. The exact R3 version uses a recommended 35 A IEC gG fuse. ABB specifies heat dissipation of 457 W and a required cooling air flow of 134 m³/h. The wall-mounted enclosure has IP21 / UL Type 1 protection. R3 height is 583 mm with cable connection box and 490 mm without it. The unit is 203 mm wide and 231 mm deep. Documented weight is 16 kg. The catalog also lists a maximum motor cable length of 200 m without output choke and 250 m with the assigned NOCH-0030-6X choke. This records the power stage, current ratings, control modes, control connections, cooling and mechanical installation data of the exact ACS550-01-031A-4 version.
