Zhejiang Tianpusheng Electric Co., Ltd. is one of the largest manufacturers of electric energy meters in Taizhou City, Zhejiang Province, China. One of the products we promote is prepaid electricity meter, let’s briefly introduce it below:

Prepaid watt-hour meters are also called quantitative watt-hour meters and IC card watt-hour meters. In addition to the measurement function of ordinary watt-hour meters, users first buy electricity, and then can use electricity. If the user does not continue after the electricity is used up If you buy electricity, it will automatically cut off the power to stop the power supply. It is used to measure AC single-phase active energy with a rated frequency of 50Hz, and realize the management function of paying first and then using electricity. Adopt advanced microelectronic technology for data collection, processing and storage, and use radio frequency card to transmit data. Its performance indicators comply with GB/T17215-2002 and GB/T18460.3-2001 standards. It has the characteristics of small size, high safety, high reliability, and anti-theft.

The electric energy meter is composed of two main functions: one is the electric energy metering part, which uses a dedicated integrated electric energy metering chip to calculate the sampling signals of voltage and current, and generates a metering pulse representing electric energy directly used for electric energy error verification, and at the same time to the MCU The functional processing part of the CPU performs energy counting; the second is the microprocessor MCU control part, which calculates the energy according to the electric energy pulse of the metering part, and exchanges data through the radio frequency card interface. At the same time, it uses a wide temperature range LCD to display and press the setting The parameter-controlled magnetic-holding relay controls the user's power consumption.

With the comprehensive advantages of price, quality and technology, the company sells its products everywhere. If you are interested in purchasing our products, please click on the link to contact us: prepaid electricity meter manufacturers.
