STS Prepayment Three Phase Smart Energy Meter Support IP54
Product Introduction
The STE38-A is an STS standard compliant, keypad type, automatically valve controlled prepaid energy meter. The integrated keypad is offered to enter recharge TOKEN and check information by short codes. Pay as you go function and excellent anti-tamper feature like magnetic field protection to help utilities for revenue electricity protection and consumer management.
As customers demand more and more products; the battery will also have higher and higher requirements. So we went through all kinds of tests and selected the most suitable battery for our product. The batteries are high in energy, with a high stored energy density, 6-7 times higher than lead-acid batteries. Long service life, can reach up to 8 years; High power bearing capacity; Self discharge rate is very low; Light weight, high temperature adaptability, and explosion-proof, green environmental protection. Then our Pay as You Go function can also solve the problem of water charge collection and management. Even if the user's economy is not too rich, but also at any time to charge at any time, do not need to pay a lump sum for a long time of water charges and feel troubled; And suppliers don't have to spend a lot of money and manpower to urge customers to pay their water bills because they haven't paid. This benefits both the user and the supplier.

Main Functions
|
1.Prepaid function:users can only get electricity after payment 2.Alarm for low credit:buzzer will constantly give alarm when low credit 3.Function of load control:meter can be programmed for load control threshold, If the current power is more than threshold. The meter will cut off user load 4.Available for self-testing:it can test LCD and relay etc. and report the results directly 5.Available for anti-tamper:meter will automatically close the valve after detection of magnetic field and open cover event 6.Available for TOU tariff:TOU tariff can be set as agreed 7.Overdraft Collection:electricity overdraft can be collected day by day or month by month 8.Recording the event:meter can record the tamper event, open cover event, purchase event and TOKENS. |
Application
Count electricity consumption over users’ period time. When the meter runs out of power, a warning is issued, and the main system can remotely control the switch and disconnect the network, so the user can no longer use the power. Only when the user recharges and enters the corresponding TOKENS, the network will be connected remotely and the user can continue to use it. In this way, the user can avoid the situation that the user defaults on the electricity bill but continues to use electricity endlessly, and help the supplier to better manage the user.
