Uses and Scope of Application
DTSY7026-SD, DSSY7026-5D three-phase four-wire electronic prepaid smart energy meter has multiple functions such as electric energy measurement, load control and user information management. It is a new type of card-type prepaid energy meter with various functions such as power measurement, load control and user information management.
The meter is the ideal product for reforming the electricity system, realizing the commercialization of electricity, solving the difficulty of charging and regulating the load status of the power grid.
It is an ideal product for reforming the electricity system, realizing the commercialization of electricity, solving the difficulty of charging and regulating the load status of the power grid.
This product has the features of anti-interference, high precision, anti-stealing, long life, one meter with multiple cards, one card with multiple meter control, convenient meter reading, etc. It is a new type of card-type prepaid energy meter with various functions,
The product is characterized by anti-interference, high precision, anti-stealing, long life, one meter with multiple cards, one card with multiple meter control, and convenient meter reading. This series of electronic three-phase energy meters have two access methods: direct access or through the mutual This series of electronic three-phase power meter can be accessed in two ways: directly or through the inductor access type. The performance indexes of this product are in line with GB/T 17215.321-2008 Level 1 and Level 2 Static AC Active Meters.
The performance indexes of this product meet all the technical requirements of GB/T 17215.321-2008 “Level 1 and Level 2 Static AC Active Meter” and GB/T18460-2001 standard for electronic three-phase prepaid energy meter.
and GBT18460-2001 standards for electronic three-phase prepaid energy meters.
Functional Features
1、Active power measurement, no need to adjust for long-term work.
2、Pre-payment function: pay the fee first and then use the electricity, automatic disconnection of electricity in arrears, automatic energization after renewing the fee and re-swiping the card;
3、Normal display alarm function: the electronic three-phase pre-payment energy meter has the following features 3, often show the alarm function: you can set the user's often show the alarm value, when the remaining power is lower than this value. Remind the user to purchase electricity in time.
4、Overdraft function: can be set to allow overdraft, when the remaining power to 0 can continue to measure electricity, until the overdraft is completely cut off. Until it reaches the overdraft amount to completely cut off the power;
5、Power failure alarm function: you can set the user's power failure alarm value, when the remaining power reaches the power failure alarm value, the meter will automatically power off. When the remaining power reaches the power failure alarm value, the meter will automatically power off, and then the power can be energized after inserting the card to remind the user to purchase electricity immediately.
6、Power failure function: when the remaining power in the meter reaches zero, the meter will automatically power failure.
7、Over power disconnection: when the power exceeds the set value, the meter will disconnect to protect, when the load is reduced, the meter will automatically restore power; and When the load decreases, the meter will be automatically energized again.
8、Ladder tariff function: optional ladder tariff function (software implementation);
9、A card function: support for a card multi-meter, can realize the water, electricity card;
10、Adopting logic encryption card and dynamic encryption algorithm, it has high anti-counterfeiting and data security.
All components in the meter are long-life and highly reliable electronic components, thus it has the characteristics of long life and high reliability.
Long life and high reliability.
11、RS485 communication can be extended.
