STS prepaid meters can actually be designed like this

STS (Standard Transfer Specification) is a standard transmission protocol for prepaid meters, which was established in South Africa in 1997 as the STS Association organization and standardized as IEC62055 by the International Standards Association in 2005, becoming the only public prepaid transmission standard in the world. Most of African countries adopt STS meters, and some countries in Southeast Asia also have applications. Yongtailong, as a long-established company in energy meter export, has several series of STS split Power meter to meet the needs of different markets.

This time Yongtailong also launched a miniaturized, intelligent din rail series STS prepaid kWh meter, with greater innovation points in function, let me carry out the secret.

1. Basic parameters:

ü voltage 230V

ü current 100A

ü frequency 50/60Hz

ü accuracy level 1.0

2. Communication mode: to adapt to different application environments.

ü HPLC

ü 4G

3. Anti-tamper design:

ü Live wire and neutral wire two-way metering to prevent bypass tamper;

ü Meter cover open;

ü Terminal cover open;

ü Strong magnetic field tamper;

ü Occurrence of tamper for event recording and alarm.

4. Safety protection:

ü When the voltage exceeds the threshold value break the relay to stop power supply to protect the load for over-undervoltage alarm;

ü when the load power exceeds the set threshold value break the relay to stop power supply to protect the line for over-undervoltage alarm.

5. Temperature detection:

ü the meter is designed with terminal temperature detection function to prevent the event of fire due to poor contact current increase;

ü when the temperature is greater than the set threshold disconnect the relay to stop power supply to protect the line for over-temperature alarm.

6. Built-in high-quality magnetic holding relay to achieve insufficient balance automatically disconnect the relay, the occurrence of alarm events automatically disconnect the relay.

The din rail mounted STS smart meter adopts STS standard transmission protocol and IDIS communication protocol for uplink communication, which is the leading mainstream product in the market. From ordinary STS power meter, anti-tamper STS meters, STS communication meters to the current STS smart meters, yongtailong has carried out iterative research and development and formed several product series. In terms of technology application and product functions, we will play the advantages of our own rich technical deposits and forward-looking product design with multiple customer groups to provide value to our customers.
