Detailed Product Description
The electronic energy meter is a new generation watt hour meter using the achievements of microelectronic technology. It is an energy meter of high precision, high reliability, large load capacity, low power consumption, multifunction and long life developed and produced by the HANGYUAN COMPANY with the most advanced specific IC and high grade components according to the international technology. That's why it is an ideal product replacing the original mechanical watt-hour meter.
Comparing with the mechanical induction watt-hour energy meter, this meter has the following advantages:
1. High precision: 1.0 class precision, produced within the 0.5 grade precision;
2. Low power consumption:0.10.2VA for circuit. The circuit power loss can be reduced a lot by this kind of circuits.
3 Maintenance-free: The precision of the meter is constant (over 10 years) and it doesn't need regular calibration.
4 It is small and light. It works normally no matter it is installed in any direction.
5 Anti-electricity stealing: Its two sides metering function and its small sampling resistance can prevent the electricity stealing of outside bucking, short and adding magnetic field.
The IC card electric prepaid energy meter is the aim of the energy metering for it is more reliable and better than other metering methods. It has the advantage besides the advantages of the electronic energy meter:
1. Prepaid electric charges: speed up the capital turnover of the power supply departments and ensure the power commercialization.
2 Not necessary to copy the meter readout: The IC card that records the consumer data automatically can simplify the meter readout copy.
3 Capacity setup: The power supply department can set the maximum current of the meter according to the various requirements of the consumer. The meter will power-off when the consumer capacity exceeds the capacity limit and resume the power supply.
4 Damage and attack proof: The built-in E2PROM memory can store the data for over 20 years and the built-in protection circuit can get rid of the outside attack.
5 High privacy: The operator can only operate it with its own password. The IC card is made of the technology of the SIM card and can't be decoded. the watt-hour meter coincides with all the technical requirements of the standard GB/T18460.32001Prepaid Energy Meter and GB/T172151998Class 1 and 2 C Static AC Active Energy Meter".
