JTQ smart electricity m
Product Description:
The main functions and features of products：
1.This product under GB/T18460-2001 "IC pre-paid card sales points
system," Design and Production.
2. The high accuracy, the high overload, the redundant reliability,
the low power loss, against steal the electricity.
3.The register demonstrates the total electricity consumption, the
numerical code demonstrated that the dump energy and each kind use
electricity the condition.
4.The excess load power failure warning, the dump energy
insufficient warning reminds the user to buy the electricity
promptly.
5.The load switch uses the high overload capacity, the redundant
reliable magnetism guard relay.
6.The use of encryption cards and dynamic encryption algorithm, the
data will not be declassified. Pre-electricity users, smart card
password settings, the smart card data transmission.
7.Reading back the remaining electricity, the total consumption of
electricity, the purchase frequency of information.
8.Dump energy warning and zero electric quantity power control.
9.Single-phase, three-phase pre-paid electricity meters to share a
set of the sale of electricity system.
