IC card meter
Introduction
1 with a variety of anti-theft feature, starting current, no creeping, wide load, low power consumption, the error curve is straight, long run-time stability.
Local control of single-phase electric meter fee
Two beautiful appearance, small size, light weight, easy to install.
3 accuracy: all-electronic design, built-in import dedicated chip, accuracy is not frequency, temperature, voltage, high harmonics.
4 Long life: using SMT technology, optimized circuit design,Electric energy meter the whole circuit without adjustment after leaving the factory.
5 Low power consumption: the use of low-power design, reduce line loss.
6 Pre-charge; IC card to transfer data, data readback, including: readback total capacity, remaining capacity, the table of cumulative electricity purchased, the total
purchase frequency information.
7 Save the table constant, the initial value, the user address, name and other information.
8 overload alarm off, remaining battery alarm to alert users buy electricity.
