ABB ACS550 Variable Speed Drive – 15kW, 3-Phase 380-480V, 31A
The ABB ACS550-01-031A-4 is a wall-mounted variable speed drive (VSD) for three-phase motors on 380-480V supplies. It delivers 15kW at 31A in normal duty and 11kW at 23A in heavy-duty applications. The ACS550 series is widely used across pumping, ventilation and general machinery for energy saving, soft starting and process control.
Key Features
- Energy savings: matching motor speed to actual demand substantially reduces consumption on pump and fan loads.
- High efficiency: IE2 efficiency class, with complete drive module efficiency up to 97% (IEC 61800-9-2).
- Controlled start and stop: removes the mechanical shock and inrush current of direct-on-line starting.
- Built-in control panel: on-board keypad for commissioning, parameter setting and fault diagnostics.
- Wide supply tolerance: 380-480V, 47.5-63Hz, suiting Tanzanian mains and generator supplies.
