Product Detail

Functional Features

Beidou/GPS timing

Can be connected to a separate external time synchronization device or shared with the original system clock.

Voltage flicker

If the difference between the maximum peak values of the two adjacent wave heads of the voltage waveform exceeds the set threshold, immediately start recording (-1 ~ +30s).

Voltage sag

If the voltage of any phase is lower than the set threshold, immediately start recording (-1 ~ +30s).

Voltage oscillation

Oscillation is difficult to prevent and poses serious harm. When the oscillation amplitude exceeds the set threshold, immediately start recording (-1 ~ +30s).

Voltage deviation

The transient voltage waveform contains a DC component, and when the amplitude exceeds the set threshold, the recording is immediately initiated (-1 ~ +30s).

Voltage surge

External surge, power transmission, protrusion, sudden load rejection, etc., exceeding the set threshold, immediately start recording (-1 ~ +30s).

Voltage grounding

When a single-phase grounding fault occurs in the system, accurately identify the fault and its occurrence time, and immediately start recording (-1 ~ +30s).

Voltage short circuit

When a phase to phase short circuit fault occurs in the system, accurately identify the fault and its occurrence time, and immediately start recording (-1 ~ +30s).

Routine power quality monitoring

Voltage fluctuation, load current, power analysis, THD monitoring, imbalance monitoring, etc. No need to install other power quality monitors.

Frequently Asked Questions

QHow does the Beidou/GPS timing feature synchronize with existing systems?

It can be connected directly to a separate external time synchronization device, or it can share the clock with your original system.

QWhat trigger conditions initiate immediate recording for voltage anomalies?

Immediate recording (-1 to +30 seconds) is initiated if the voltage of any phase falls below the set threshold (voltage sag), if the difference between adjacent wave heads exceeds the threshold (voltage flicker), or if voltage oscillations, deviations, surges, grounding, and short circuits occur and exceed configured limits.
