Description
Mid-range digital excitation.
Did you know
- The ABB UNITROL 1020, part of the UNITROL 1000 series, was launched in October 2012 alongside the UNITROL 1010. This series replaced older models like the UNITROL 1000-7 and UNITROL 1000-15, which entered a limited support phase in 2019.
- The UNITROL 1020 is positioned as a high-performance automatic voltage regulator (AVR) within ABB's UNITROL 1000 family, designed for larger synchronous generators and more demanding operating environments compared to the UNITROL 1010 and UNITROL 1005. It offers extended functionality and robust protection capabilities.
- The UNITROL 1020 is chosen for its powerful and compact design, capable of delivering excitation currents up to 20A for continuous operation in small to medium-sized synchronous generators and industrial equipment. Its advanced microprocessor technology, IGBT semiconductors, and dual-channel support enable features like advanced load distribution, rotating diode monitoring, and automatic synchronization for parallel running units.
| Model | Max Continuous Excitation Current (A) | Voltage Regulation Accuracy | Communication Interfaces |
|---|---|---|---|
| UNITROL 1020 | 20 | ±0.2% at 25°C | USB, Ethernet, CAN, RS485 (Modbus RTU), Modbus TCP |
| UNITROL 1010 | 10 | ±0.5% | Modbus RTU, Profibus DP, Ethernet TCP/IP |
| UNITROL 1005 | 5 | Not specified | Modbus TCP |
