Product description
The ABB ACS355-03E-07A3-4 is a frequency converter from the ACS355 series for general machinery drives. Its complete type code identifies a three-phase version with a connected EMC filter for 50-Hz mains and a voltage range of 380 to 480 V. ABB specifies a typical motor power of 3.0 kW at 400 V and a rated output current of 7.3 A for this variant. The device belongs to frame size R1 and has an IP20-/UL Open construction for control-cabinet installation. The motor frequency can be parameterised from 0 to 599 Hz. ABB states 4 kHz as the default switching frequency, adjustable from 4 to 16 kHz in 4-kHz steps. For short load peaks, the manufacturer documents 1.5 times the rated output current for one minute in every ten minutes and 1.8 times the rated output current for 2 s at start-up. A brake chopper is integrated as standard. The programmable control connections comprise two analogue inputs, five digital inputs, one analogue output, one relay output and one transistor digital output. Depending on configuration, optional fieldbus adapters can provide PROFIBUS DP, CANopen, Modbus RTU, EtherNet/IP, Modbus TCP, PROFINET IO, EtherCAT or POWERLINK connectivity. For the exact R1 frame size, the ABB catalogue lists 107 W heat dissipation and 24 m³/h cooling airflow. The specified ambient temperature range is −10 to 40 °C, extending to 50 °C with derating. Without fastenings and the clamping plate, the device measures 70 mm in width, 169 mm in height and 161 mm in standard depth. This frame size weighs 1.2 kg. The type code, current rating, voltage range and frame size distinguish this 3-kW version from adjacent ACS355 variants.
