Name: ABB ACS350 Inverter Drive 11kW 400V – Manual & Price Quote
Brand: ABB

Description

Overview

The ABB ACS350 inverter drive, model ACS350-03E-23A1-4, is a general purpose AC frequency inverter for 11kW (15HP) 400V three phase motors, providing variable speed control for standard AC induction machines with V/f or sensorless vector control. It is part of the ABB ACS350 drive family designed for simple, quick installation and commissioning.

With a 23.1A output current and 380-480V three phase input, the drive covers the common power range used in pumps, fans, conveyors, and other industrial machines.

Engineering & Design

The drive is supplied in an R3 size frame (169 mm wide x 169 mm deep x 202 mm high plus 34 mm cable clamp plate) with an IP20 enclosure for wall or cubicle mounting in clean environments. It provides 150% overload for 60 seconds and a speed control range of 0 to 500 Hz.

Braking is supported to a 50 Ohm minimum external resistor. Standard I/O includes two analogue inputs, five digital inputs, one analogue output, one digital output, and one relay contact set, with a basic keypad for local operation. Drives can be programmed from a PC using FlashDrop, and the unit is rated for 40 C ambient with 75 mm ventilation space above and below; side-by-side mounting is permitted.

Motor control reliability depends on drive quality, and the ABB ACS350 inverter drive provides it, which is why Seven Star LLC supplies the ABB ACS350 inverter drive for industrial motor control projects.

The ABB ACS350 inverter drive controls the speed of the three phase AC motor with the scalar and the vector control modes. The drive is installed in the cabinet or on the wall with the mounting kit, and the parameters are set with the control panel or the PC tool. The built-in EMC filter and the brake chopper simplify the installation for the pump, the fan and the conveyor applications.

The ACS350 drive is set up for the motor parameters with the control panel and the starting values are entered from the motor nameplate. The digital inputs are assigned for the start/stop and the speed selection, and the relay output repeats the fault status to the control circuit. The drive is protected with the input fuses and the EMC filter is connected for the plant standard. The parameter backup is stored in the panel memory for the quick recovery.

Why Seven Star LLC

Seven Star LLC supplies the ABB ACS350 inverter drive for motor control projects across the Gulf, with verified part numbers and technical support. Our team assists with drive selection, parameter setup guidance, and spare part planning.

We serve oil and gas, water, and industrial customers with reliable B2B supply of drives and motor control equipment throughout the GCC.

Drive Performance

The ACS350’s 150% overload capability and 0-500 Hz speed range cover the demanding duties found in pumps, fans, and conveyors, while the V/f and sensorless vector modes give the application engineer the right control strategy for the machine. The FlashDrop configuration tool reduces commissioning time and errors.

The IP20 R3 frame with side-by-side mounting capability simplifies panel layout, and the standard I/O complement covers the typical control interface requirements without extra modules.

Reading the ACS350 Type Code

The type code on the rating label tells you what the drive is, and it is the quickest way to confirm a like-for-like replacement:

ACS350 – the product family.
03E – three-phase input unit.
23A1 – rated output current of 23.1 A.
4 – the 380–480 V supply class.
+J404 – option code for the basic control panel supplied with the drive.

When replacing a failed drive, also check the motor nameplate. Sizing on motor current is more reliable than sizing on kW, especially for older or rewound motors, and heavy-starting loads may need a larger drive.

Installation Checklist

Mount the drive vertically with the clearances above and below, and size cabinet ventilation for the drive losses at your ambient temperature.
Use symmetrical shielded motor cable, with the shield bonded 360° at the cable clamp plate and at the motor terminal box.
Fit input fuses or a breaker as the ABB manual specifies for this rating, and keep control wiring apart from motor cables.
On IT (ungrounded) supplies, disconnect the internal EMC filter as described in the manual.
If a braking resistor is used, respect the 50 Ω minimum and give the resistor its own thermal protection.

Commissioning Steps

Choose the application macro that is nearest to your wiring, then adjust individual I/O parameters.
Enter the motor nominal voltage, current, frequency, speed and power from the nameplate.
Select V/f or vector control; run the motor ID run if you use vector control and the load can be decoupled.
Set the minimum and maximum speed, acceleration and deceleration ramps, and the current limit.
Test start/stop, speed reference and the fault relay with the control system, then save a parameter copy to the panel or with FlashDrop.

Maintenance and Common Faults

Most field problems with a working drive come from heat and dirt. Clean the heatsink and check the cooling fan at planned intervals. Overcurrent trips often point to ramps that are too short or to a motor or cable insulation fault; overvoltage during stopping points to a deceleration ramp that is too fast for the load inertia or a missing braking resistor. Keep a record of the fault log before resetting, as it helps trace intermittent problems.

Applications in Oman and the GCC

In the Gulf, 11 kW drives are common on booster pumps, cooling tower fans, AHUs and conveyors. Summer cabinet temperatures can exceed the 40 °C rating, so plan output current derating or cabinet cooling, and fit dust filters that are cleaned regularly.

About brand

ABB, formed in 1988 and headquartered in Zurich, covers an unusually long stretch of a plant's equipment list, from the flowmeter and analyzer in the field to the drive, breaker and protection relay in the electrical room.

Seven Star LLC is an independent supplier serving Oman and the GCC. Our ABB listing concentrates on measurement and analytics: ABB flowmeters, liquid analysis sensors and systems, level and pressure instruments. It also includes valve actuators, low voltage circuit breakers, ABB drives, soft starters and protection relays.

ABB product families on this page

Flow measurement includes ABB electromagnetic, Coriolis, vortex and swirl meters, sold under names such as ProcessMaster, AquaMaster, CoriolisMaster and SwirlMaster. Liquid analysis covers pH, conductivity and dissolved oxygen sensors with their transmitters. SensyTemp TSP sensors handle temperature. On the electrical side the listing has ACS355 machinery drives, the ACS550 general purpose drive, the ACQ580 for water and wastewater and the ACS880-01 industrial drive, with fieldbus adapters such as the FPBA-01 for PROFIBUS DP.

Where ABB instruments and drives are used

Water and wastewater plants use the electromagnetic flowmeters, analyzers and ACQ580 drives together. Oil and gas, power and chemical plants specify the Coriolis and vortex meters, pressure and level transmitters and the 615 series relays for motor and transformer feeders. The drives run pumps, fans, conveyors and compressors in almost every industry.
