Technical Specifications Voltage input: 2 channels, 120 V AC nominal, 50/60 Hz; phase angle range: 0–360°; trip window: ±5° to ±180° adjustable; output contact: SPDT, 5 A at 250 V AC; supply voltage: 24 V DC ±10%; accuracy: ±1° at 60 Hz; operating temperature: -20 °C to +70 °C; enclosure: IP40.
Functional Features Adjustable phase angle trip window; SPDT contact output; phase angle direction detection; leading/lagging indication; dead band adjustment; phase sequence insensitive operation.
Application Scenarios Generator synchronizing phase check, phase protection relays, synchronizer backup phase check, motor synchronizing circuits, phase angle monitoring systems.
Performance Parameters Phase accuracy: ±1° at nominal voltage; operate time: < 20 ms; hysteresis: 1° typical; frequency dependence: < 0.5° over 45–65 Hz.
Material Composition Phenolic housing, phase-shift network, precision comparator circuit, electromechanical output relay, adjustment potentiometer.
Structural Characteristics Round panel mount case; front adjustment screw and indicator; rear screw terminals; mounting lock ring.
Working Principle The module compares the phase angle between the two AC input signals using a phase comparator network. When the phase difference falls within the adjustable window, the output relay changes state to indicate phase match.
