ABB: a Swiss-Swedish group formed in 1988
ABB was formed in 1988 by the merger of two old companies: the Swedish ASEA (founded 1883) and the Swiss BBC Brown Boveri (founded 1891) — hence the acronym ASEA Brown Boveri. The headquarters is in Zurich, Switzerland. Today ABB is one of the four world leaders in industrial automation (alongside Siemens, Schneider and Mitsubishi), with manufacturing and service in more than 100 countries. Tier — premium, corporate; price-wise roughly the level of Schneider, above INVT or Veichi, but with long service support for product lines and thorough documentation.
ABB's defining trait is breadth: from frequency converters and electric motors to industrial robots, power grids and switchgear. In drives the brand has a strong school of its own — the ACS series with Direct Torque Control (DTC), which delivers a fast torque response without an encoder. Engineers come to us for ABB in two cases. First: the brand is named explicitly in the customer's specification and an analogue will not pass review. Second: the engineer deliberately wants DTC control for a heavy mechanism (cranes, winders, extrusion) or wants the drive to fit an existing ABB ecosystem on site. If there are no such requirements and the budget is tight, we say it straight: for the same ordinary task a Danfoss drive or a lower-tier drive will do the same for less. Paying extra for ABB is justified for specific things — DTC, ecosystem, service — not for the nameplate.
What ABB we keep in stock and to order
The catalogue holds over 170 ABB items across two lines — ACS frequency converters and PSR/PSE/PSTX soft starters. Below is a map with links to the relevant sections.
ACS frequency converters
Main series: the entry-level ACS150, machine-grade ACS180, general-purpose ACS480 and ACS580, heavy industrial ACS880, plus a dedicated ACQ80 line for water supply and pump applications. Section: ABB frequency converters. The popular ACS150 and ACS580 at 0.75–11 kW are usually in stock; heavy large-frame ACS880 units are normally made to order.
PSR / PSE / PSTX soft starters
Three series: the compact PSR, the managed PSE, and the PSTX with a built-in bypass and a full set of protection functions. Section: ABB soft starters. Most in demand for pumps, fans and compressors.
ACS frequency converters: which series for which task
A brief breakdown by series; more on the page ABB frequency converters:
| Series | For | Stands out by |
|---|---|---|
| ACS150 | Simple machines, conveyors, small pumps and fans | Entry-level compact drive, minimal setup, low cost within the brand, on-board potentiometer |
| ACS180 | Machine building: machine tools, packaging equipment, conveyor lines | Machine drive with vector control, flexible configuration, good dynamics for its class |
| ACS480 | General-purpose machine-level applications needing a wider option set | Extended functionality versus ACS180, built-in safety options, convenient setup menu |
| ACS580 | Pumps, fans, conveyors, compressors (general purpose) | Vector control, energy-saving functions, PID, sleep mode; covers "ordinary" industrial tasks well |
| ACQ80 | Water supply, pumping stations, wastewater | Water-dedicated functions: pump cascade, dry-run protection, impeller cleaning, pipe-fill modes |
| ACS880 | Heavy industrial equipment: cranes, extruders, winders, rolling mills | Direct Torque Control (DTC), high overload capability, braking module, flexible scalability |
Before ordering we ask: what load torque (constant or variable), what mechanism it is, whether water process functions are needed (then ACQ80) or a fast torque response for a heavy mechanism (then ACS880 with DTC). Setup details are in frequency converter commissioning.
ABB soft starters: PSR, PSE, PSTX — which one, and when a VFD
Choice logic in brief (more in pros and cons of soft starters on the shop floor and why soft starters are needed):
Direct-on-line suits a motor up to roughly 5.5 kW with no requirements for inrush current or mechanics — that is the cheapest. An ABB soft starter is chosen when you need to remove water hammer in a pump or a jerk on a conveyor but do not need to regulate speed in operation: PSR is the compact basic option for simple applications, PSE has controlled ramp-up and ramp-down and broader protection, PSTX has a built-in bypass, extended diagnostics and communications. An ACS VFD is fitted when you need variable speed, energy saving on a pump or fan by a pressure sensor, or precise control. Before sizing a soft starter we ask for motor power, start mode and whether a bypass contactor is used (in the PSTX it is already inside).
Notes from practice: where ABB really fits, and where it is overpaying
In our experience ABB means predictability and a strong drives school. ACS150 and ACS580 have been in our turnover for years, failure rates in line with the class, documentation detailed, firmware and service available. A separate advantage is DTC in the ACS880 series: for mechanisms with complex mechanics and fast-torque requirements it genuinely works and often lets you do without an encoder. Thermal regime — the standard rule: provide cabinet ventilation and do not mount the drive against other heat sources. ABB fits where:
the object follows corporate standards and the specification names a particular brand, and review will not pass an analogue; it is heavy industrial equipment — cranes, winders, extrusion, rolling — where the DTC control of the ACS880 gives what a simple drive cannot; the object is infrastructural and long-lived (power, utilities, large industrial sites), where spare-part and firmware availability over 10+ years matters; the operations team is already trained on ABB.
Overpaying happens when an ACS880 is bought for a simple pump "because it is ABB", while the task is just to spin an aggregate, with no DTC, no regeneration and no process functions needed. In that case a cheaper ACS150 or ACS580, or even a lower-tier drive, covers the same job. We talk this through honestly with every customer: yes, it is expensive — but for specific things (DTC, ecosystem, service), not for marketing.
What to check before buying ABB in Ukraine
The checklist we go through with a customer:
1. The right ACS series for the task. Not "ACS" but specifically ACS150, ACS580 or ACS880 — different classes and prices. For water with pressure by a sensor — ACQ80; for a heavy mechanism with DTC — ACS880, not ACS150.
2. Overload class. Heavy Duty (constant torque: conveyors, cranes) or Normal Duty (pumps, fans) — this affects frame-size selection in the ACS580 and ACS880 series.
3. Braking resistor or module. For dynamic applications (cranes, centrifuges, frequent braking) this is a separate line in the spec — easy to forget. In the ACS880 the braking module may be built-in or external depending on the frame size — confirm it.
4. Water process functions. If you need a pump cascade, dry-run protection, PID by a pressure sensor — confirm it is the ACQ80 or an ACS580 with the right macro, not a basic ACS150.
5. Service and spares. A 24-month warranty through the official service; confirm repair turnaround and spare-part availability for your series.
6. Stock availability. The popular ACS150, ACS180, ACS580 are usually available; heavy large-frame ACS880 and non-standard versions are made to order — allow a few days for delivery.
7. Documentation. Before installation pull the manual for your exact firmware version from abb.com — there are parameter and macro differences between series sub-versions.
Not sure which ACS line fits your object — write to a manager with motor power, load type and what exactly you need (drive only, drive with water process functions, heavy drive with DTC, soft starter). We will suggest a specific series and what of it is in stock.
