Basler SSR 32‑12 Static Voltage Regulator

The Basler SSR 32‑12 is a static voltage regulator designed for synchronous generators operating at 50, 60, or 400 Hz. It features an exceptionally wide sensing voltage range of 120‑600 VAC, making it suitable for diverse generator applications including aerospace, military, and industrial power systems. This regulator provides precise excitation control with fast transient response and robust protection.

Key Features

The regulator offers adjustable voltage setpoint, stability compensation, and droop control for parallel operation. It includes over‑excitation and under‑excitation protection. The wide frequency range allows use in variable‑speed or constant‑frequency systems. The unit is equipped with LED indicators and test points for easy commissioning.

Technical Specifications

Sensing voltage: 120‑600 VAC, 50/60/400 Hz. Auxiliary power: 120‑240 VAC. Output: up to 150 VDC, 5 A continuous (12 A peak). Regulation accuracy: ±0.5%. Response time:<30 ms. Operating temperature: -40°C to +70°C. Enclosure: panel mount with IP20 protection.

Operating Principles

The regulator compares the sensed generator voltage with a reference. The error signal controls the firing angle of the SCR bridge to modulate exciter field current. The control loop is optimized for stable operation across the frequency range. Droop compensation ensures proper reactive power sharing in parallel systems.

Applications

This regulator is used in aerospace ground power units, military generator sets, variable‑speed diesel generators, and industrial co‑generation plants. Its wide sensing range and frequency support make it highly versatile.

Installation and Configuration

Mount the unit on a panel. Connect sensing, power, and field wiring. Adjust setpoint, stability, and droop via potentiometers. Commission with a load test to verify performance.

Maintenance and Reliability

Solid‑state design ensures high reliability. Routine inspection of connections and cleaning is sufficient. The regulator includes protection against short circuits and overvoltage.

Conclusion

The Basler SSR 32‑12 static voltage regulator offers wide sensing and frequency flexibility, delivering reliable excitation control for specialized generator applications.
