Ac direct current detection device -AMDD

Ac direct current detection device -AMDD


Product application: application to substation or power plant, dc power system ac signal into dc system real-time monitoring and alarm?


The device adopts ARM as the main control chip, with high integration level, strong anti-interference ability, fast running speed and low power consumption;

All parameters can be set through the battery detection device (DJX) operation interface.

All alarms are exported through the sound and dry contact points;

The device provides serial data communication interface (RS232, RS485, Ethernet interface) and external device connection;

Through the battery detection device (DJX) device, record more than 500 accident alarm information and waveform;

The device adopts real-time tracking information processing technology to solve the recording and alarm of the communication signal to the dc fault, showing the communication waveform and the time of the tamper;

Real-time full digital bandwidth measurement, full range measurement dc power ripple voltage value, and calculate ripple coefficient value, effectively record the ac content in dc power supply.
