UNITROL1020-0006 3BHE030579R0006 brushless excitation system

The UNITROL 1020 is a voltage regulator in the UNITROL1000 series designed for small and medium-sized

synchronous generators and industrial equipment. The UNITROL 1020 combines performance control with a simply designed power circuit.

UNITROL 1020 is a powerful small indirect excitation system with built-in support for dual channels for advanced

load distribution, rotating diode monitoring, automatic synchronization and multiple all-in-one communication options in parallel running units.

The UNITROL 1020 is a voltage regulator in the UNITROL 1000 series designed for use in small and

medium-sized synchronous generators and industrial machines. IGBT semiconductor devices based on

advanced microprocessor technology and allowing current outputs up to 10ADC for continuous operation. The

UNITROL 1020 performs high performance in harsh conditions and different temperature ranges and is fully

compliant with DNV and UL standards. The additional features of UNITROL 1020 compared to the previous

version are Ethernet,USB connectivity, data and event logging and many new features.

The UNITROL® 1000-7 and UNITROL® 1000-15 entered the limited phase of its life cycle in 2019. In this phase, ABB’s
services and support are limited to the availability of key components and migration planning to the latest technology is
recommended.
Upgrade benefits
• Long-term availability of parts, by considering a replacement, users can capitalize on the features of a product still in its
active phase, thereby eliminating any risks associated with equipment entering the obsolete stage.
• Minimum shutdown and commissioning time: the extremely flexible and powerful UNITROL 1010 and UNITROL 1020 are
the optimal products for replacement, where electrical interface and SW is fully backwards compatible.
• Long-term availability of engineering and support competences, including 24/7 telephone support.
