ABB UNITROL 1020-0003 3BHE030579R0003 excitation controller modules

The ABB UNITROL 1020-0003 (3BHE030579R0003) is an excitation controller module designed for specific applications in power systems. Here is a detailed introduction:

General Characteristics

It is part of the UNITROL 1020 series, which is known for its reliable performance and advanced features in excitation control. The module is designed to provide precise control over the excitation of synchronous generators, ensuring stable operation and efficient power generation.

Technical Specifications

Input Voltage Range: It is likely to be designed to operate within a specific input voltage range, such as 85 - 132 V AC. This wide range allows it to be compatible with different power supply systems, providing flexibility in installation and operation.

Rated Current: With a rated current of 0.5 A, it can handle the excitation current requirements of small - to - medium - sized synchronous generators effectively. The module is designed to provide the necessary current to maintain the generator's magnetic field at the appropriate level for optimal performance.

Control Accuracy: It offers high - precision voltage control, typically maintaining the generator output voltage within a tight tolerance, such as ±1% of the set - point value. This ensures stable power supply quality and protects the connected electrical equipment from voltage fluctuations.

Response Time: The module has a relatively fast response time, which is crucial for quickly adapting to changes in the generator's operating conditions, such as load variations or grid disturbances. It can adjust the excitation current within a few milliseconds to maintain the stability of the power system.
