Products Characteristic
1)more functions and high precision
Distribution intelligent monitoring terminal has strong data collect and disposal function and it can monitor dozens of (even hundreds )electric degree, at the same time ,it has 3-phase 4-wires voltage ,current harmonic real-time analysis of 3-19 times , electrical energy pulse output ,over electrical degree to alarm ,the most value record statistics, record 15minuts gap a kind of measuring quantity of electricity, data memory 3 months.
2)Communication grope web has strong function .
The communication function of distribution intelligent monitoring terminal is very strong .It has two ways light and electric separate RS-485/RS-232 gorge line one and RS-485 gorge line two .It support open way’s gorge communication pact and user can select different communication ways according to yourself need .The communication method can select UTP ,Coaxial Cable ,Data Radio and GPRS and it can compose high and economic electric monitor web with other monitor unit.
Display and operate easy
Distribution intelligent terminal monitor sampling 128*64 point LCD display and film button and maybe through button to select display measuring parameter or setting all of parameter. All of setting parameter in the meter of not lose memory .If power cut ,the data will not lost ,otherwise user can use homologous system parameter setting to set software and through the communication to parameter setting.
4)Installation convenient and nimble
Distribution intelligent terminal monitor has two ways of installation of embedded chips and wall hanging chips , it can satisfy the request of different scene.
5)High safety
Distribution intelligent terminal monitor select a kind of anti-high jamming software /hardware step, it can safety and reliability to operate in strong magnetic field area and the reliability is so high.
