ACS150-03E-08A8-4 Variable Frequency Drive ACS150 4.0kW 3-ф/380

ACS150-03E-08A8-4 is an ABB ACS150 rated 4.0 kW, three-phase 380 V input, three-phase 380 V output, 8.8 A. This is the most powerful model in the ACS150 series — the top of the range.

Typical applications:

• Powerful workshop supply/extract ventilation
• A 4 kW water-supply pump with PID pressure hold
• A 4 kW conveyor, crusher or woodworking machine

Note: this is the ACS150 ceiling — if you need more than 4 kW the series will not do, look at a higher-power drive. For new projects with vector control and Modbus, consider the Veichi AC310. Scalar V/Hz, no fieldbus.

ABB ACS150 — component drive for simple speed-control tasks

The ACS150 is the entry tier of ABB's older drive lineup. Scalar V/Hz control, a 0.37–4 kW range, and setup in a few minutes from a built-in panel with a potentiometer. It is a drive for OEM machines and simple jobs: mixers, conveyors, fans, booster pumps, gates. The series is discontinued — ABB's direct successor is the ACS180. If you still run a working ACS150 and need a like-for-like but cheaper replacement, we usually fit a Veichi AC10 or AC01.

What the ACS150 is good for

• Fans and booster pumps 0.37–2.2 kW: the built-in PID holds pressure or flow without a separate PLC.
• Conveyors and mixers up to 4 kW: the built-in brake chopper gives fast braking of an inertial mechanism — the resistor connects directly.
• Single-phase 1-ph/220 V supply: the 01E models take a single-phase mains and output three-phase 220 V to the motor — handy where there is no three-phase feed.
• Serial OEM machines: FlashDrop copies parameters between drives with no power applied — configuring a batch of identical machines in seconds.

How the ACS150 differs from modern equivalents

Honestly: in features the ACS150 is a simple V/Hz drive with no fieldbus. If you want the same simple logic but a new drive with a warranty and Modbus, take the AC10. If you need vector control and a wider power range, take the AC310.

When the ACS150 is NOT the right choice

• You need SCADA supervision — the ACS150 has no embedded Modbus; see the Veichi AC310 with built-in Modbus RTU.
• High breakaway torque or precise torque at low speed — you need a vector drive such as the Veichi AC01.
• Dusty or damp environment — the ACS150 is rated IP20 and goes inside a cabinet only; otherwise look at an enclosed IP54+ drive.

Our experience with the ACS150

We are often contacted by owners of older ABB gear whose ACS150 has reached the end of its life and is no longer available to buy. As a rule we match the replacement 1:1 by power and supply — a single-phase ACS150 for a single-phase drive, a three-phase one for three-phase. If you need advice on motor or brake-resistor compatibility, we will help for your specific job.
