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.

Features and Functions: 

1. Active energy measurement;

2. Adopt 20-digit token as data transmission media, you can purchase energy before consumption;

3. Double loop measurement both on neutral and phase lines,

4. Accumulate the total energy with unit of 0.01 kWh;

       5.  Display the real-time current and voltage;

       6.  LCD display with backlight;

       7.  Low energy alarm to remind you to purchase energy;

       8. Double relays to control the neutral and phase circuits;

       9. Infrared communication for data transmission and parameter settings;

       10. Event record function (including cover opening event, tamper event and power failure event, etc.)

       11. Ground line connection design;

       12. Anti-tampering features( including opening terminal cover, short circuited, current injection, reverse wiring, magnetic disturbance, etc.)
