DT1/G series voltage monitor
Shunyang brand DT1/G (mounting type) series voltage monitor is a grid voltage quality monitoring statistical instrument with MCS-96 series single-chip 16-bit microcomputer as the core. It can convert and process the read voltage signal. Under the synchronous control of, it automatically counts various data and stores the statistical results for selective output when users need it.
The DT1/G series voltage monitor can collect, display and classify the voltage signals of up to three channels of power grids. It is convenient to set the starting date of monthly statistics. In the fully functional DT integrated data management system software and With the cooperation of the positive voltage qualification rate management system software, a series of tasks such as statistical summary of voltage data, report generation and rapid reporting can be realized.
The DT1/G series voltage monitor adopts a true RMS/DC (TRMS/DC) converter for each voltage signal, which can accurately and real-time measure the true RMS of various voltage waveforms. Its data storage chip uses ferroelectric memory (FRAM), which has super features such as unlimited writing, ultra-low power consumption and long-term data retention when power is off.
DT1/G series voltage monitors all adopt digital tube display (5 digits brightly display the voltage value, 6 digits brightly display the time, 4 or 5 digits brightly display the percentage of the pass rate, the upper limit rate or the lower limit rate), and the display period is 1s, the operation panel is intuitive, clear and easy to use.
The DT1/G series voltage monitor is equipped with an RS232 (or RS485) interface for collecting statistical data (or connecting with a computer). It is also equipped with an "online verification interface" that matches the "voltage monitor verification device". Conveniently realize online verification.
When the user requests, the DT1 series voltage monitor can be equipped with 1 minute voltage over-limit output relay contacts to facilitate remote monitoring or linkage control; it can also be built-in or external GSM, GPRS wireless data transmission terminal or LAN wired data transmission The terminal is convenient for remote data interaction.
The DT1/G series voltage monitor adopts an iron chassis and a plastic cover, and its external shape is similar to a three-phase electric energy meter. Its overall size is 260×150×98mm3, and the installation dimensions are as follows:
