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.
