ABB UNIROL1010 3BHE035301R0001 Excitation System Controller

If you’re managing a marine power system or maintaining diesel-electric locomotives, this controller might be the solution you need. We’ve had customers in offshore drilling operations mention how its voltage regulation stability cut downtime by 30% during critical operations. Designed for medium and small synchronous generators, it handles environments from arctic wind farms to tropical marine installations.

We see this controller used most frequently in hydro turbine installations and wind power converters. One customer in Norway retrofitted their aging diesel generators with this model and reported “cleaner voltage waveforms and fewer AVR adjustments.” For system compatibility, we commonly pair it with ABB’s AC10272001R0101 power modules and 3BHB013088R0001 I/O cards. Its Ethernet/USB connectivity makes integration with modern SCADA systems straightforward.

Our Value Proposition

With 16 regional warehouses worldwide, we can typically ship this controller within 24 hours. Our 12-month warranty covers both defects and performance issues – one customer in Singapore had a unit replaced free of charge after encountering humidity-related issues in a coastal power plant.
