Basler SSR 32‑12 Static Voltage Regulator

The Basler SSR 32‑12 is a static voltage regulator designed for brushless synchronous generators. Identified by part number 9 1859 00 100, this regulator offers reliable voltage control with fast transient response. It is part of the SSR series known for their robust construction and simple adjustment, making them suitable for a wide range of industrial and marine generator applications.

Key Features

The SSR 32‑12 features adjustable voltage setpoint, stability compensation, and droop control for parallel operation. It includes over‑excitation protection and under‑excitation limiting. The unit is equipped with LED indicators for power and fault status. Its compact design allows easy integration into existing control panels.

Technical Specifications

Input sensing voltage: 110 to 480 VAC, 50/60 Hz. Auxiliary power: 120 to 240 VAC. Output voltage: up to 150 VDC for exciter field. Continuous output current: 5 A, with a peak of 10 A. Regulation accuracy: ±0.5%. Response time: less than 30 milliseconds. Operating temperature: -20°C to +65°C. Enclosure: IP20 rated for panel mounting.

Operating Principles

The regulator compares the sensed generator voltage with an internal reference. Any deviation generates an error signal that adjusts the firing angle of the SCR bridge, modulating the exciter field current. The PID control loop ensures stable performance across load changes. Droop compensation adjusts the voltage setpoint in proportion to reactive current for stable parallel sharing.

Applications

This regulator is used in standby and prime power generators, marine vessels, and co‑generation plants. It is suitable for applications requiring precise voltage control and reliable excitation support.

Installation and Configuration

Mount the regulator on a panel using the provided brackets. Connect the sensing leads, auxiliary power, and field wiring. Adjust the voltage setpoint, stability, and droop using the front‑panel potentiometers. Commissioning with a load bank is recommended to fine‑tune the settings.

Maintenance and Reliability

The solid‑state design ensures high reliability with no moving parts. Routine inspection of connections and cleaning of the unit are sufficient. The regulator includes protection against short circuits and overvoltage for extended service life.

Conclusion

The Basler SSR 32‑12 static voltage regulator delivers dependable excitation control with flexible adjustments, making it a trusted component for generator voltage regulation.
