1. Both-way electric energy metering: provides precise positive-negative active energy metering and one-way accumulating; used for power metering and advance purchase of AC single-phase current rated
2. Advance purchase quantity, preset maximum load-limit and IC card password; IC card transfers data and realizes data including total consumption, remaining quantity, accumulated quantity and total purchases) backward reading
3. Storage of leave-factory serial number, meter constants, initial data and the user's name and address
4. Alarm and switch off when overload; alarm at low remaining power to remind user of timely purchasing
1. Remote control, it is easily operated by user
2. Complete sealed up, no exposed bayonet to prevent breaking.
3. It is easily to be installed.
4. The meter section adopts the special VDSL and has the functions of high sensitivity, high precision, wide measuring range, long lifespan. It can meter 1 to 20 times harmonization wave power.
5. It adopts infrared remote control card and dynamic data encryption technique to confirm the user information. One card only for one meter, fake card is forbidden.
6. It adopts high-power bistable latching relay to switch frequently in the heavy current mode.
7. It adopts double data checkup and back-up to confirm the data security. The data can be stored for over 20 years as the power is cut off.
8. Low starting current, accurately measure the small & heavy current and no creeping, the user should not change the meter as the load increases.
9. The user can use the infrared card to read all the balance electricity quantities back to the system, the system can analyze the data to count the power consumption and profit & loss.
10. As the meter can't work because of the error, it will automatically cutoff to decrease the power consumption
11. As the voltage is over its setting value, the meter will automatically cutoff the power to protect the equipment and start the inside guard circuit to protect itself from burning down.
12. As the current load is over the setting value, the meter will automatically cutoff the power.
13. As the balance is 0 and relay can't cutoff the power, the meter will measure normally; the balance is negative value that will be reduced from the next purchasing quantity.
14. It can test the current power and record the maximum load within this purchasing term.
