Single Phase Two Wire STS Prepaid Meters Keypad Prepayment Meter for Residential Usuage
Single phase electric meter DDSY150-SSK is a new type of electric meter having the prepayment function. The user can purchases energy from the vending network by getting the serial number ( named as “ TOKEN”), which could be entered via keypad to load the pre-purchased energy. The TOKEN contains 20 digits which are encrypted. Because the activity of recharging is realized by keypad, this meter is named as “ Keypad Meter”. This meter is equipped with infrared communication port, double metering sensors, double control switches, real time clock unit, and other auxiliaries.
The data transmissions protocol of DDSYXXXX complies with IEC62055-41 and IEC62056-21. All the specifications and performance index comply with IEC62053-21 regulations to Class 1.0 Static Meters for Active Energy.

- 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.
