Technical Specifications AC voltage sensing input channels, adjustable frequency and phase window, relay output for breaker control, built-in voltage regulation and breaker time compensation, DIN rail or panel mounting.
Functional Features Automatic synchronization check, voltage difference detection, frequency difference monitoring, phase angle control, breaker closing command output, status LED indication.
Application Scenarios Diesel generator sets, power plant auxiliary power systems, backup generator parallel control, marine power generation systems.
Performance Parameters Precise phase angle detection, fast synchronization response, adjustable closing time compensation, stable operation across wide ambient temperature range.
Material Composition Flame-retardant plastic housing, fiberglass control circuit board, electromechanical relays, copper terminal blocks, LED indicators.
Structural Characteristics Compact rectangular housing, front panel with adjustment potentiometers and status LEDs, rear terminal block for field wiring, DIN rail mounting clips.
Working Principle Continuously measures generator and busbar voltage, frequency and phase difference. When all parameters fall within preset limits, it outputs a breaker closing signal to connect the generator to the busbar.
Installation Requirements Mount on DIN rail or control panel, connect generator and busbar voltage sensing wires, wire breaker control circuit, configure thresholds via front panel adjustments.
