STS Split Type Prepaid Meter STS standard
General introduction
1) It adopts STS standard encryption algorithm to exchange the information based on TOKEN.
2) Advantages of the meter are high metering accuracy, high level security, strong compatibility, easy operation, etc.And has the functions such as communication and load control,metering, monitoring, alarm, display, etc.
3) The meter has Anti-tamper funvtions : Detecting current reverse, magnetic influence, phase bypass, meter cover open, terminal cover open etc., at the same time, the meter can disconnect power supply which is configurable when the tampers occur.
4) Work with UIU.
Main functions
- UIU communication interface: PLC, RF or twist-wire is optional.
- Events logs: Detecting and recording events such as current reverse, magnetic influence, phase bypass, meter cover open, terminal cover open, overvoltage, under voltage, etc.
- Audio and visual alarm: Audio and visual alarm which can be configurable can be for power flow reverse, magnetic influence, phase bypass, meter cover open, terminal cover open, etc.
- Communication interface: Optical port and RS485 interface are available.
- Step tariffs
- TOU: Four tariffs; two sets of time zone tables; two sets of time period tables; It support public holidays and weekends
- Load control: Detecting the customer's load status, it can alarm or disconnect the load when verload.

Utility benefit
Friendly power supply: Support emergency credit. Bring better experience for customers
On the basis of ordinary meter, The meters adds many new functions, such as measurement information management, information management of energy consumed, monitoring of energy quantities consumed, etc.
It has the bidirectional metering function and supports the distributed energy utilization. If the user is self-built with distributed clean energy generation facilities, such as wind energy, solar energy, etc., it can realize to transmit the spare energy to power grid when the generated power cannot be exhausted, thus improve the users' economic benefits.
It adopts digital metering technology, supports various actual requirements.It’s the technology base to achieve distributed power measurement, two-way interactive service, smart home and intelligent community.
