Description
Legacy SR-series AVR.
Did you know
- The Basler Electric SR4A series of static voltage regulators, including variants like the SR4A2BO6B3A, are solid-state automatic voltage regulators. The SR4A retrofit model is designed as a direct replacement for older Basler SR4A regulators.
- The SR4 is part of Basler Electric's range of voltage regulators, which also includes the SR8A series and the AVC63-7 series. The SR4A is generally suited for small to medium-sized synchronous generators, while the SR8A series is also for industrial and marine power generation systems, and the AVC63-7 is often used for medium-output generators.
- The SR4 is chosen for its accurate voltage regulation, robust solid-state design, and suitability for retrofit applications. It offers features like under-frequency roll-off for engine protection, over-excitation, and field short-circuit protection, and is designed for high immunity to electrical noise.
| Model | Output Current (Continuous) | AC Power Input | Regulation Accuracy | Response Time |
|---|---|---|---|---|
| SR4A (e.g., SR4A2BO6B3A) | 6 A DC | 120/240 VAC | ±0.5% | < 25 ms |
| SR8A (e.g., SR8A-2B15B3A) | 7 A DC | 240 VAC | Not specified, but generally precise | Not specified |
| AVC63-7 | 7 Adc at 63 Vdc | 170 to 305 Vac | Better than ±0.25% | < 16 ms |
