Smart Card Prepaid Energy Meter Single Phase Two Wire KWH Meter Reverse Current Display
Smart Card Prepaid Energy Meter Single Phase Two Wire KWH Meter Reverse Current Display
DDSY150 series electronic single phase watt hour meter is a high technology product adople avanced IC technology as well as SMT technology, both circuit design and componects selectior are up to various working environment to guaranty that power meter can operate steadily for a lor time. The finished meter don't neet to be adjusted so that the calibration cycle is long. It extremely reduce the labor force of the electricity board for calibrating power meters. The feature of the products are anti-thief, long life, high accuracy, high reliability, low power consumption small volume, light weight, the meter is up to the according to iec 1036-96 and GB/t17215-200 standard.
1. Main Features:
● EnergyMeasurement
Total and time-sharing forward active & reactiveenergy measurement
Total and time-sharing reverse active & reactiveenergy measurement
Save last one to sixteen months energy data
● IC Card TransferSpecification
Credit data transfered from a point of sale (POS) orvending system is made into IC card using
the Standard Transfer Specification(STS) encryption techniques, which comply with IEC62055 protocol
● Load control function
When the residual energyis 0 or the allowable overdraft that both sides agreed, this meter will
sendout power-off signal to have load switch cut off power.
The power will berecovered automatically after inputting new purchased energy amount.
● Programmable low creditwarning
The meter can beprogrammed for setting user credit warning threshold,
When the meter's residualenergy is equal to credit warning threshold, the meter will start theaudio & video warning function in a way of warning light flashing
● Tamper detection
With event recording function (includingcover-opening event, tamper event and power failure event)
● Optical port interface
Communication standards DL/T645-2007, 1200bps forcommunication
Support IEC62056-21protocol
● RS-485 serial interface
Communication standards DL/T645-2007, 2400bps forcommunication
SupportIEC62056(DLMS/COSEM) protocol
● LCD display
Number of digits value field Up to 8
Digit size 4x10mm
