Basler Electric SR8A-2B06B3E – Static Voltage Regulator
The Basler Electric SR8A-2B06B3E (also designated SR8A2B06B3E) is a compact static voltage regulator designed for generators requiring up to 6 A of field current. It provides precise, stable excitation control with adjustable voltage setpoint, stability, and droop compensation.
Features and Performance
The regulator uses a PWM power stage for high efficiency and low heat generation. It accepts 120/240 V AC sensing inputs and delivers a regulated DC output. Voltage setpoint, stability, and droop are all field‑adjustable. Under‑frequency roll‑off protects against overvoltage during overspeed.
Input sensing: 120/240 V AC, 50/60 Hz
Output current: 6 A continuous (8 A surge)
Output voltage: up to 90 V DC
Regulation accuracy: ±0.5% of setpoint
Voltage adjustment range: ±10%
Droop adjustment: 0–5%
Under‑frequency roll‑off: adjustable 45–60 Hz
Protections: over‑excitation limiting, short circuit
LED indicators: power, regulation
Mounting: panel or chassis with heat sink
Operating temperature: –20 °C to +60 °C
Applications
This regulator is suitable for generators up to 400 kVA in industrial, marine, and standby applications.
Installation and Tuning
Mounting is via four screws, with connections through screw terminals. Trimpots allow rapid field tuning.
Reliability
Built with industrial‑grade components and conformal coating, it ensures long‑term reliability.
In summary, the Basler Electric SR8A‑2B06B3E provides precise, reliable excitation control in a compact package.
