ABB UNIROL1010 3BHE035301R0001 Excitation System Controller

The ABB UNIROL1010 3BHE035301R0001 excitation controller is built for precision in voltage regulation and excitation control. Designed for medium-to-small synchronous generators and industrial machinery, it combines IGBT semiconductor tech with microprocessor-driven architecture to deliver stable 10A DC output. Perfect for environments where reliability matters – think diesel engines, turbines, or wind power systems.

Technical Specifications:
Manufacturer: ABB
Series: UNITROL 1000
Model: UNIROL1010
Output: 10A DC (continuous)
Technology: IGBT semiconductors
Interfaces: Ethernet, USB
Standards: DNV, UL

Common applications include diesel/gas engine systems, hydro turbines, and marine power setups. One customer mentioned it’s “a lifesaver on offshore platforms where vibration and humidity would kill lesser controllers.” We frequently pair this module with ABB’s UNITROL 1020 systems for seamless upgrades, and it plays well with steam turbines and wind farms too.

What sets this apart? Dual-channel support enables parallel operation for load sharing and automatic sync – handy for critical power plants. The diagnostics package cuts maintenance time by flagging issues early. We’ve seen installations where this module outlasted competitors’ units in extreme heat. Plus, the USB interface makes firmware updates straightforward, which field engineers appreciate. Redundancy’s baked into the design, so if one channel falters, the other keeps running. Pair it with ABB’s Profinet modules for full system integration or use it standalone in locomotive setups.
