Split Keypad Single Phase Prepaid electricity meter
The STE18-S is an STS Standard compliant, Split keypad type and single phase prepaid electricity meter.
Our single phase meters are devices used to measure electricity consumption in ordinary household circuits, which are used to supply power to various household appliances.Single-phase meter has the characteristics of low energy consumption (adopting low power consumption design, reducing the power grid line loss) and high reliability, which is an ideal product for reforming the power system and realizing the commercialization of electric energy.
Because each region and each customer's requirements for meter payment methods are different, some customers need pre-paid meters, while others need post-paid meters.Therefore, in order to meet the needs of different users, we set up two charging modes for electricity meters.And these two kinds of payment mode transformation, just need to input a string of corresponding short code can be realized.
Main characteristics
● Meter Recharge By Inputting TOKEN
● Active energy measurement
● MD(maximum demand measurement)
● Auto scroll mode display
● Build-in relay control
● Event log
● Low Credit Alarm
Main Functions:
●Prepaid function: can only use water after paying, close water valves after running out of water.
●Low credit alarm:when the remaining electric quantity is less than the alarm quantity, the electricity meter often shows the remaining electric quantity to remind the user to buy electricity.
●Prepaid & post-paid switch:meter can be switched to prepaid mode or post-paid mode.
●Measurement function:user can measure the electricity consumption,the credits,etc.
●TOU Tariff:utilities can set step price on request.
●Event recording:meter can record the tamper event, open cover event, purchase event and TOKENS.
●Self-testing:meter has a self-test function, it can test LCD and relay etc. and report the results directly.
●Anti-tamper:meter will automatically close the valve after detection of magnetic field and cover-opening event.
●Overdraft Collection:electricity Overdraft can be collected day by day or month by month.
●Communication:the meter is available with AMI system through LORA RF or Bluetooth 4.0 on request.
●Load control function:meter can be programmed for load control threshold, If the current power is more than threshold. The meter will cut off user load.
●Information Inquiry:consumer could check the data like credit remain, total purchased and total credit by inputting the short code.
