Input voltage: 110V AC, 120V AC or 240V AC.
Square shape panel 96 x 96mm.
3 bi-colored LED indicators for "SYNC", "GEN" and "BUS".
24 LEDs in a circle display the phase angle and the frequency differences between 2 networks.
360° indication.
12 o'clock position LED is bi-colored.
PC window, ABS resin frame, PC case.

Operation Principle

1) Initially, SYNC, BUS and GEN LED's are lit Red and the outer ring will show a single Red traveling LED. When voltage and phase angle are unmatched the outer ring LED rotates according to the system phase difference.

2) When the BUS voltage is at ±10% of nominal system voltage, the BUS LED will change from Red to Green signifying proper BUS voltage has been established. When the GEN voltage is at ±10% of nominal system voltage the GEN LED will change from Red to Green signifying proper GEN voltage has been established.

3) Finally, once all system voltages match and the systems are synchronized, the SYNC LED will change from Red to Green. All LED's are now Green when the systems are synchronized.
