Technical Specifications Generator and busbar sensing: 120–480 V AC, 50/60 Hz; output: 4–20 mA bias signal to AVR; voltage matching accuracy: ±0.5%; supply voltage: 24 V DC; operating temperature: -20 °C to +70 °C; enclosure: IP20; dead band: 0.25–2% adjustable.
Functional Features Automatic generator-busbar voltage matching; proportional bias output to AVR; adjustable dead band; over/under voltage limit; reverse polarity protection; status indication.
Application Scenarios Generator paralleling voltage matching, automatic synchronizing systems, multi-generator power plants, standby generator grid connection.
Performance Parameters Voltage matching accuracy: ±0.5%; response time: < 200 ms; output linearity: ±1% full scale; sensing accuracy: ±0.25%.
Material Composition Flame-retardant plastic housing, precision voltage transformers, differential amplifier circuit, output driver, insulated terminals.
Structural Characteristics Rack plug-in module; front status LED; rear screw terminal block; standard mounting footprint.
Working Principle The module measures both generator and busbar voltage, calculates the difference, and outputs a proportional 4–20 mA bias signal to the generator AVR to raise or lower excitation until generator voltage matches busbar voltage within the preset dead band.
