Single-phase and Three-phase Remote Fee-Controlled Intelligent Electricity Meters
Single-phase and Three-phase Remote Fee-Controlled Intelligent Electricity Meters is an intelligent electric energy metering product developed and produced by our company, which is suitable for the metering of single-phase AC active energy with a stable voltage of 220V and a frequency of 50Hz. The product is equipped with one channel of 485 communication port, which can support real-time meter reading function and remote control of opening and closing functions; the product adopts high-reliability copper resistance, current transformer, and high-precision metering chip to complete the metering function, making the product with high Accuracy, high reliability, long life, accurate measurement and other advantages. The electric energy meter uses the transformer to reduce the voltage to process the AC high voltage. It ensures and adapts to a wide voltage range, and the whole machine does not need to be adjusted after leaving the factory. It can be widely used in single-phase alternating current measurement occasions such as urban, rural or factory enterprises.
Single-phase and Three-phase Remote Fee-Controlled Intelligent Electricity Meters Compliant with GB/T18460.3-2001 "AC Measurement Equipment: Special Requirements Part 21 Prepaid Electricity Meters". GB/T617215.321-2008 "Current Measurement All technical requirements of the Particular Requirements for Equipment Part 21 Static Active Energy Meters (Class 1 and Class 2). The factory verification is completely in accordance with JG596-2012 "Electronic Electric Energy Meter Verification Regulations", and 485 communication and other functions are strictly tested in accordance with DL/T645--2007 "Multi-function Energy Meter Communication Protocol".
DDZY2888 single-phase cost-controlled smart energy meter is a product for measuring electric energy. It has some functions: measurement function, display function, measurement function, data storage function, 485 communication and other functions.
can. The details are as follows.
Metering function: The pulse constant of the electric energy meter is 1200imp/kWh, that is, when the pulse light flashes 1200 times, the electric energy meter measures 1 kWh, 120 times, 0.1 kWh, and 12 times, 0.01 kWh. according to
The electronic energy meter verification regulations require that the product measurement accuracy is required to be level 1.
Display function: The single-phase charge-controlled electric energy meter uses a segment LCD to display the data at the meter end of the electric energy meter. When the user is using electricity normally, the electric energy meter will display the current accumulated electricity consumption, current voltage value, current current value and meter number in a circular manner.
