Product Description Model NO.: DDSY168 Installation: Direct Connected Electric Equipment: Single-phase Power Meter Connection: Terminal Type: Energy Meter Customized: Customized Communication Protocol: Dlms/Cosem Transport Package: Standard Packing Origin: Shenzhen China Display: Digital Usage: Multi-Functional Energy Meter, Watt-Hour Meter, Meter for Industry and Home Use, Standard Electric Energy Meter, Prepayment Meter, Reactive Energy Meter, Multi-rate Watt-hour Meters, Maximum Demand Meter Theory: Static Meter Measured Signal: Pulse Peak Certification: RoHS, ISO, CE Communication Type: GPRS Trademark: CALIN Specification: IEC 62053-21 Main FeaturesEnergy Measurement Total and time-sharing forward active & reactive energy measurement
Total and time-sharing reverse active & reactive energy measurement
Save last one to sixteen months energy data20 digit Standard Transfer Specification(STS) Credit data transfered from a point of sale (POS) or vending system is made into a numeric token  in a 20 digit number using the Standard Transfer Specification (STS) encryption techniques, which comply with IEC62055 protocol Load control function When the residual energy is 0 or the allowable overdraft that both sides agreed, this meter will send out power-off signal to have load switch cut off power. The power will be recovered automatically after inputting new purchased energy amount. Programmable low credit warning The meter can be programmed for setting user credit warning threshold, When the meter's residual energy is equal to credit warning threshold, the meter will start the audio & video warning function in a way of warning light flashingTamper detection With event recording function (including cover-opening event, tamper event and power failure event)Optical port interface Support IEC62056-21 protocol, 1200bps for communicationRS-485 serial interface Support IEC62056(DLMS/COSEM) protocol, 2400bps for communicationLCD display Number of digits value field Up to 8, Digit size 4x10mmCommunication modules GPRS module:EGSM900/DCS1800 dual-band, support GSM/GPRS phase2/2+ protocol
