The GSM GPRS 3G 4G Power Distribution Monitoring System is not only a smart power meter for measuring the power distributor voltage, current, factor, watts, frequency, active power, reactive power, when over current or exceed the pre-set value, will alarm immediately.
Mainly Features:
1.ARM® Cortex™-M4 32 Bit RISC Core, 72MHz inside, RTOS system;
2.Quad-Band GSM Frequency,3G, supports SMS and Voice and GPRS/3G communication;
3.Programmable by SMS Commands or PC Configurator via USB;
4.A/B/C phase power up it directly, Inbuilt large capacity rechargeable backup battery;
5.Suitable for three-phase four-wire system, input voltage: 100~400V, input current:0~5A;
6.Monitoring A/B/C 3 Phase input over current, over voltage , factor, watts, active power, reactive power exceeds alarm;
7.Power input PT,CT rate are programmable;
8.Accuracy of current, voltage is 0.2 class, power and watts is 0.5 class, sampling is 0.1seond.
9.Large internal memory can save 1000 event historical data;
10.6 analog inputs, 16bits, supports 0-5V, 0-20mA, 4-20mA. |
