Le ABBACS550-01-031A-4 is part of ABB’s ACS550 standard/general purpose drive family, engineered to provide reliable speed control for a wide variety of industrial motors and processes. With a normal-duty rating of 15 kW (20 hp) et 31 A at 3 × 380–480 V, and a heavy-duty rating of 11 kW with 23 UN, it covers both variable torque applications such as pumps and fans and constant torque loads such as conveyors and mixers. The drive operates from a 3‑phase 380–480 V, 48–63 Hz supply and delivers output frequencies from 0 à 500 Hz, giving flexibility for standard and high‑speed applications.
The ACS550-01-031A-4 comes in a wall-mounted IP21 enclosure (IP54 variants exist on closely related options), with integrated EMC/RFI filter (category C2) and line choke for harmonic reduction, simplifying installation and compliance with EMC standards. Built‑in RS‑485 (EIA‑485) with Modbus RTU support allows direct connection to PLCs and building management systems without extra communication modules. The drive includes a dynamic swinging choke to reduce harmonics, temperature‑controlled cooling fan for reduced noise and longer life, and coated boards for improved protection against dust and contaminants.
Control features include sensorless vector control for improved torque at low speed, built‑in PID control (two independent PID loops on the ACS550 platform), programmable 2 entrées analogiques, 6 entrées numériques, 2 analog outputs and 3 relay outputs for flexible integration. Adjustable acceleration and deceleration times from 0.1 à 1800 seconds enable smooth starting and stopping tailored to mechanical load requirements. Standard protections cover overcurrent, surtension, sous-tension, surcharge du moteur, and overtemperature, helping to protect both drive and motor in harsh industrial conditions.
Physiquement, the ACS550-01-031A-4 offers a compact wall‑mount form factor: typical dimensions are around 203 × 583 × 231 mm with about 16 kg weight, making it suitable for mounting directly in control rooms or plant areas. User‑friendly parameter menus, macros (such as Pump and Fan macros), and an optional control panel help reduce commissioning time and simplify setup for common applications. Dans l'ensemble, this model is a robust, versatile 15 kW drive for OEMs and end users who need a standard, proven VFD platform.
