Product use

Single phase cost controlled intelligent energy meter is used to measure AC single-phase active energy with a rated frequency of 50Hz, achieving the management function of paying before using electricity.
This product is manufactured using dedicated ultra large scale integrated circuits and SMT technology. Key components are made of well-known brands of low-power, long-life devices. The overall design adopts various anti-interference technologies to improve the reliability and service life of the product. The data display adopts a large screen Chinese LCD for easy meter reading.
This product can directly and accurately measure the positive and negative active power, and perform multi rate measurement based on the corresponding rate settings. It can store the total energy and energy data for each rate for up to 12 settlement days. It has event recording function. Supports 2 annual time zones, 2 daily time period tables, 8 daily time periods, and 4 types of rates. It also has infrared and RS485 communication functions, which can achieve remote meter reading, and the communication protocol follows DL/T645-2007. Its performance indicators comply with GB/T 17215.321-2008 and GB/T18460.3-2001 standards.

start

Start

At a power factor of 1.0 and a current of 0.4% Ib, the energy meter can start and continuously record.

shunt running

Defluction

When the energy meter applies 115% of the reference voltage and there is no current in the current circuit, the test output of the energy meter will not generate more than one pulse.

Installation, wiring, and testing

Installation, wiring and testing

The electric energy meter can be installed and used after passing the inspection and being sealed with lead before leaving the factory.

The electric energy meter should be installed indoors for use. There is a hook screw hole on the upper end of the base of the electric energy meter, which can be fixed with hook screws; There are two mounting holes at the bottom of the electric energy meter, which can be fixed to the terminal block with screws; The base plate for installing the electric energy meter should be placed on a sturdy and fire-resistant wall, and it is recommended to install it at a height of about 1.8 meters. The installation location of the electric energy meter is shown in the following figure:
