ACS180-04S-09A4-4 Variable Frequency Drive ACS180 4.0 kW 3x380

ACS180-04S-09A4-4 is a 4.0 kW ABB drive, three-phase 3×380 V supply, 9.4 A. A workhorse rating for pump and ventilation units and mid-power conveyors.

Typical applications:

• 4 kW pump in water supply or a process line
• Fan in a supply/extract air-handling unit
• Conveyor, small crusher or mixer

Note: the 9.4 A rated current — size the motor no larger than the drive. Sensorless vector control for stable torque, energy optimization, embedded Modbus RTU. On larger frames (R2 and up) a built-in brake chopper is present — useful for controlled conveyor stops; for the actual braking you will need an external resistor of the right power.

ABB ACS180 — compact machinery drive for serial-built machines

The ACS180 is ABB's entry-level machinery VFD covering 0.25–22 kW. Its job is straightforward: give OEMs and integrators a reliable compact drive without extra options, but with what a machine actually needs — sensorless vector control, embedded Modbus RTU and a built-in Safe Torque Off (STO) safety function. It is effectively the modern replacement for the older ABB ACS150 and ACS355 in the lower machinery class. If you want a "mount it in the cabinet and it runs" drive for a pump, fan or conveyor, this is a workhorse.

Where the ACS180 fits

• Pumps and fans: built-in energy optimization lowers motor flux at partial load — less current, quieter operation. Typically 0.7–22 kW.
• Conveyors: sensorless vector control holds torque at low speed; larger frame sizes include a built-in brake chopper for controlled stops.
• Compressors, mixers, winders: ABB lists mixing and winding machines among the series applications.
• Single-phase supply: the "1" variants run from a 1-phase 230 V mains and deliver a 3-phase output — handy where only a single domestic phase is available but the motor is three-phase (up to 3 kW).

How the ACS180 compares

Honestly: on motor control the ACS180 and budget Veichi drives in this class are close. You pay for the ABB name, embedded SIL3-rated STO, long support and service. If the machine is simple and the budget is tight, Veichi AC10/AC01 will cover the same job for less.

When the ACS180 is NOT the right choice

• You need closed-loop encoder feedback, high dynamics, or PROFINET/EtherCAT — go to ABB ACS380/ACS580 or a drive with a PG card. The ACS180 is sensorless and Modbus-RTU-centric.
• Power above 22 kW — out of the series range; see larger drives.
• A very simple single machine on a tight budget — consider Veichi AC10/AC01.

Our experience with the ACS180

In practice the ACS180 is bought exactly for serial machines and typical engineering jobs — pump, ventilation, conveyor. Two questions come up most often. First, single-phase input: yes, the "1" models run from 230 V one phase and drive a three-phase motor up to 3 kW. Second, braking: the built-in chopper is present from frame size R2 upward, so for the smallest enclosures confirm it for your specific case. EMC filtering also depends on the variant — if you have strict electromagnetic-compatibility requirements, agree on the exact part number before ordering. We will help you match the model to your mains and motor.
