Structure and Function Features of IC Card Smart Meter
1. Accurate: All-electronic design, built-in imported special chip, accuracy is not affected by frequency, temperature, voltage, high harmonics.
2, electronic structure, accurate measurement, strong anti-interference ability.
3, IC card smart meter long life: Using SMT technology, optimized circuit design, the whole machine does not need to adjust the circuit after leaving the factory.
4, low power consumption: the use of low-power design, reduce the power line loss. Pre-purchase electricity; IC card transfer data to achieve data readback, including: read back the total power, the remaining power, the cumulative purchase of electricity within the table, the total number of purchases and other information.
5, IC card smart meter start current is small, small current measurement accuracy.
6, with power lines over 300V automatic power-off function.
7, a form of a card, encryption IC card has perfect security measures, after the product is delivered to the user, the manufacturers can not be broken.
8, IC card smart meter with prepaid electricity bills, run out of power. Alarm power can be set to remind users to purchase electricity.
9. The management department can inquire and check the running electricity meters at any time.
10. Set the power limit value. After the power exceeds the limit, the power protection circuit will be powered off.
11, IC card smart meter also has a variety of anti-theft features, starting current, no impulsive, wide load, low power consumption.
