ACS150-03E-01A2-4

What type of device is this?

This unit is a compact inverter drive designed to control the speed of a three-phase AC motor. It is suited to applications where a fixed-speed motor needs adjustable speed control, such as conveyors, mixers, fans and pumps.

What input supply does this drive require?

This version is intended for a three-phase supply of 380 to 480 V AC, with an operating frequency range of 48 to 63 Hz. It is not the correct choice for a single-phase input system.

What motor size is it typically matched with?

This model is rated for 0.37 kW, which is approximately 0.5 hp. It is a good fit for smaller three-phase motor applications where compact variable speed control is needed.

What is the rated current of the drive?

The rated output current is 1.2 A. For the ABB ACS150-03E-01A2-4, this is the key current figure to check when matching the drive to the motor nameplate.

What motor control method does it use?

The drive uses scalar U/f motor control. This makes it well suited to general-purpose speed control duties where straightforward and dependable operation is required.

Can this drive be used for fans and pumps?

Yes. It is suitable for fan and pump duties, and it can also be used on light conveyor and mixer applications. The ACS150 range includes an integrated PID controller, which can be useful in variable flow or pressure-based applications.

Does the drive include a braking chopper?

Yes. A braking chopper is built in as standard, so an external braking chopper is not required. If a braking resistor is used with this specific model, the minimum resistor value is 200 ohms.

What control signals are available?

The drive provides one analogue input that can accept 0 to 10 V or 0(4) to 20 mA signals, five programmable digital inputs, a relay output, a 10 V reference supply for a potentiometer, and a 24 V DC auxiliary supply.

Does it have an operator interface on the unit?

Yes. The drive features an integrated control panel with display, along with a built-in potentiometer for straightforward local speed adjustment.

What enclosure rating does it have?

The standard unit is supplied in IP20 form for cabinet installation. A NEMA 1 arrangement is available as an option for applications that require that style of enclosure.

What are the mounting dimensions?

For the R0 frame IP20 version, the typical dimensions are 202 mm high, 70 mm wide and 142 mm deep. In the NEMA 1 version, the height is typically 280 mm, with the same 70 mm width and 142 mm depth.

What ambient conditions is it designed for?

The drive is designed for ambient temperatures from -10 to 40°C without frost. It can be used up to 50°C with derating. Relative humidity should remain below 95% with no condensation.

Is overload capability available?

Yes. The drive offers heavy-duty overload capability of 1.5 times the rated output current for 1 minute every 10 minutes, and starting capability of 1.8 times rated current for 2 seconds.

What switching frequency does it use?

The standard switching frequency is 4 kHz. It can be selected between 4 and 16 kHz in 4 kHz steps, depending on the application requirements.

Can it be used with longer motor cables?

Yes, but cable length depends on the installation arrangement and EMC requirements. For this model, a suitable output choke can extend the motor cable length up to 60 m.

Are EMC features included?

Yes. This drive variant includes an internal EMC filter. For applications with stricter EMC requirements, compatible external filters are available for the ACS150 range.
