DONSUN Single Phase Keypad Prepaid Energy Meter is a type of energy meter that based on universally recognized STS standard.
Normally, there will be a numerical Keypad on a separate unit called CIU (Client Interface Unit) for the client to punch in a series of 20 digit code to charge their own meter.
The communication between the meter and CIU is normally by cable, RF or PLC.
DS1000 is a good representative of our Single-Phase Keypad Prepaid Energy Meter Series.
