Product Description

II MAIN FUNCTIONS 1. Time Sharing Measurement: The watt-hour meter time-sharing measures electric quantity and total electric quantity of different rates. Time-sharing measurement can discretionarily setup 4 kinds of rate (sharp, peak, flat, trough) of no more than *0 time intervals. Be able to record *5min as one circle, the maximum demand and occurrence time while rail error equals 1min, measurement, display and storage respectively. 2. Prepayment: Users can purchase power first then use through infrared telecontrol code, carrier wave or RS**5, etc. Completely eradicates owing fee, to the benefits of funds back. Deduct electricity quantity or money is optional. 3. Alarm Power Cut: Cover with relevant controllable turnoff switch, remote on-off control; alarm while remanent electric quantity equals to or less than alarm quantity, warn the users purchase power in time; built-in control relay, while remanent electric quantity equals to zero, the power will be cut, power is only available until repurchase electric. 4. Anti-tamper: Be able to prevent such electric larceny ways as reverse electrical connection, plus magnet, sloped installation, etc. 5. Communication: Standard RS**5, RS**2 and infrared communication; hand terminal meter-reading, RS**5 remote meter-reading or high speed electric cable carrier meter-reading. 6. Real Time Collection: Real time collect meter status, voltage, current, electric quantity array, power factor, maximum current and occurrence time, maximum current delay time, rate format, maximum demand and time, overtake data, real time clock, power cut time and date of meter. 7. Freeze and Storage: Provide temporary freeze electric quantity and voltage, current and so such real time parameters. Record electric quantity data no less than *2 months, data saved forever after power cut. III MAIN FEATURES 1. High Precision: Fully electronic type design, choosing and using the imported specialized measurement chip, high precision, high sensit
