UNITROL 1010
Description
Compact digital excitation system for smaller synchronous machines.
Did you know
- The ABB UNITROL 1010, an advanced static excitation system, was unveiled in February 2026. It is a core component of ABB's UNISEX (Universal Excitation System) platform and builds upon ABB's extensive experience in excitation systems.
- The UNITROL 1010 is a mid-range Automatic Voltage Regulator (AVR) within the UNITROL 1000 series, positioned between the more compact UNITROL 1005 (for lower excitation currents) and the higher-performance UNITROL 1020.
- The UNITROL 1010 is chosen for its robust and compact design, offering stable and reliable excitation control for small to medium-sized synchronous generators and industrial machines, even in harsh environments. It features an advanced digital control platform with adaptive algorithms for precise voltage regulation and comprehensive protection.
