Description
ABB analog AVR module (service).
Did you know
- The ABB UNITROL 1000 series, which includes the AVR-RSK4001, is a compact automatic voltage regulator (AVR) series. It was the first AVR in the world to achieve German Grid Code VDE-AR-N 4110 and VDE-AR-N 4120 certification by TUV in 2019, and DNV Cyber security (Essential) Type approval (IACS UR E27) in 2024.
- The AVR-RSK4001 is part of the UNITROL 1000 series, which covers synchronous machine applications from 100 kVA to 80 MVA. Within this series, the UNITROL 1005 is designed for smaller synchronous generators, while the UNITROL 1010 and 1020 are for small to medium synchronous generators and industrial machines with current outputs up to 20 A DC.
- The AVR-RSK4001, as part of the UNITROL 1000 series, is chosen for its stable and accurate voltage regulation, fast response to load changes, and ease of commissioning and operation through the CMT 1000 software. It is also designed for reliability in harsh environments and supports global grid-code compliance.
| Model | Generator Size (kVA) | Max Excitation Current (A DC) | Voltage Regulation Accuracy |
|---|---|---|---|
| AVR-RSK4001 (UNITROL 1000 series) | 100 - 80,000 | Up to 20 | ±0.5% |
| UNITROL 1005 | Small synchronous generators | N/A (compact AVR) | ±0.5% (estimated) |
| UNITROL 1010/1020 | Small to medium synchronous generators | Up to 20 | ±0.5% |
