Monophase STS Prepaid Meters Keypad Prepayment Smart Meter with Build in Load Switch



Radarking designs and produces prepaid electric meters which are cost-efficient and ideal for the use in solutions for AMR/AMI at residential as well as industrial applications.


Radarking's prepaid meters own anti-tamper features . The meter is built with multi sensors and triggers. including tamper shutdown protection ,disconnects on overload and no credit .


As meter manufacturers, we not only produce BS mounting devices, 35mm DIN RAIL is also one of our most popular meters. Both types can work with a customer interface unit as CIU and gives consumers great convenience inquring their usage without steppiing out of their homes.


The DDSY150S combines IEC compliant accuracy metrology and DLMS/COSEM standard compatible communication technology.The feature rich device provides enhanced tamper protection, thermal shutdown, as well as programmable under and over voltage and reverse energy measurement.

Safety precautions:
- Use only isolated tools.
- Do not connect the meter to a 3 phase - 415V AC - network.
- Place the meter only in dry surroundings.
- Make sure the used wires are suitable for the max current the meter can measure.
- Make sure the AC wires are installed correctly before activating the current/voltage.
- Do not touch the meter connecting clamps directly with your bare hands, with metal, blank wire or other material as you will have the chance of an electricity shock and a possible chance for health damage.
