Key words: Split Electricity Meter ; energy meter ; prepaid meter
With the development of communication technology, the market demand for anti-tamper electricity, the STS Split Electricity Meter is extended according to the characteristics of STS prepaid meter without media recharge. Split Electricity Meter refers to the metering part, functional part of the meter and human-machine interaction part to separate, commonly known as energy meter + indoor display in the power industry.
The electric energy meter and the indoor display(IHD/CIU) are connected by wired or wireless communication, and RS485, PLC (power line carrier), RF, Wi-Fine, LoRa and other different types of communication methods will be used according to the application environment. STS Split Electricity Meter also plays a good role in preventing electricity tamper, the power bureau will use a highly sealed meter box to install the meter on an outdoor pole, the installation position is not easy for the public to reach and can not open the meter box; The act of preventing tamper without access to the meter cannot be implemented.
Today, I will share with you a series STS energy meter with CIU from Yongtailong.

II. Functional Features:
1. Communication mode RS485, PLC (power line carrier), Wi-Fine optional; It is used to connect indoor displays and remote data transmission and control management.
2. The meter has three operating modes: STS token mode, currency prepaid mode and post-paid (traditional) mode, which can be switched.
3. 8 time period and 8 tariffs
4. Neutral line measurement has anti-tamper function, Meter cover open;Terminal cover open;
5. Strong magnetic field tamper, over-under-voltage, overload event recording and alarm.
6. Self-diagnosis: EEPROM inspection, battery low alarm, relay status detection
7. Measure voltage, current, active power, reactive power, frequency, power factor, demand, electricity
8. It adopts LCD display and electric energy meter shell is made of flame retardant PC material
The man-machine interaction part of STS Split Electricity Meter (i.e. indoor display(IHD/CIU)) can be placed inside the house, so that users have more opportunities to view the electricity consumption situation conveniently, and the electricity consumption data can be fed back to users in time to enhance their awareness of electricity saving and thus play a certain effect of saving electricity. As an energy meter exporter, Yongtailong has many series of Split Electricity Meters, different communication methods, different meter mounted (din rail mounted, wall mounted), overall meter box type, etc..png)
