STS Class A Split Keypad Single Phase Smart Prepaid Electricity Meter With CIU
Product introduction
STE18-S is a split keypad single phase prepaid energy meter with CIU supporting RF-LoRa communication.It is based on STS standard and has long life.The energy meter is 1phase 2 wire,50Hz frequency,class1.0,1000imp/kWh,IP54 protection degree,IEC 62052-11 industrial standard.
First of all, the prepaid electricity meter solves the problem of the difficulty in charging property fees and guarantees the capital of the property. The prepaid electricity meter needed to be paid before the user uses the electricity and then which prevents the deadbeat from not paying the electricity fee.The electricity supply will be automatically switched off if the meter does not pay the electricity fee.
Secondly, it helps the property to solve the problem of capital shortage. Because it is prepayment management, users have to pay first and then use electricity. The property can always occupy the users’ money for buying electricity, which is conducive to the operation of funds.
Finally, it is convenient for property payment. The payment of prepaid meters can be coordinated with the system payment, which can be paid directly on mobile devices. For example, the prepaid remote meter reading system developed by our company can be paid on the third party APP, which greatly facilitates the payment of users and is conducive to improving the service quality of property.
