Overview

Single-phase intelligent monitoring °courant is a high-tech product. manufactured by specific integrated Circuits. latest microelectronics technology and SPAT process design. The control chips of this meter use professional meeting Soc supporting a current dynamic range of 5000 1. with active power measurement error less than 0 1%, this meter can provide industnal-grade precision measurement for modules This meter has higher integration level and superior anti-electromagnetic interference performance It also designed according to the features of China Power Grid. which has the characteristics such as ultra-wide operating voltage range. high reliability. long working life, high precision, and low povrerThis product can be used to measure single-pelage AC active energy weft the rated frequency 50.180/42, d types of meat the technical requirements in the laved and lever 2 static AC active energy meter of national standard GB:712215-1998

Main Features

1. Using LCD Liquid crystal display to  show electricity information. under normal use conditions the sernce, some of LCD liquid crystal display rs over 10 years
2. With power pulse output for meter calibration, and passive photoelectric isolated OC gate output port. the pulse width is 80ms±20ms. The waveform is a square wave (Optional)
3. Using super bright. long-life LED working indicator The pulse indicator red flashes when there is a pulse.
4. With the UART interface communication method, it can be expanded to other communication methods.

Installation and Use

1. Please install a power meter indoors in a dry and good ventilation environment, the base plate used to install the power meter should fixed on a solid and fire-resistant wall that is stable. recommended install height is about 1 8 meter. or install in dedicated distribution box
2. It is necessary to connect the wire according to the wiring diagram on the end box. we recommend you to connect with the copper joint to avoid the power meter being burned for the poor contact of the copper joint in the end box
3. Lightning protection measures are necessary which power meter is used at the place where a thunderstorm is frequent to avoid the meter from being burned when struck by lightning

Storage and Transportation

1. Store the power meter with the anginal packaging. storing environment temperature should be within -25 C-.70 C. relative humidity should be lower than 85% and the au should not contain gas which may cause erosion.
2. This product is an electronic device, please avoid heavy objects impact and bumping when transporting and carrying it.
3. When the outer case of the power meter has obvious cracks caused by severe shock or drop from high position dunng the transportation carrying and instalation, please do not connect wires to this power meter.

Quality Assurance

Within a year after the manufacture date of the power meter. when a user discovers the power meter cannot meet the national standard with the condition that the user use the meter according to the user s manual and the outing case is complete our company will repair or replace the meter free of charge.
