In 2016, there were 8 large-scale, moderate to severe persistent haze weather in China, which was reduced by 3 times compared with 2015. Overall, the smog treatment in recent years has achieved certain results, but Beijing-Tianjin-Hebei It is still the area with the most serious air pollution. Recently, the Urban Blue Book: China Urban Development Report No. 10, published by the Institute of Urban Development and Environment of the Chinese Academy of Social Sciences, the China Urban Economics Association and the Social Science Literature Publishing House, recently pointed out the above problems.
The Blue Book believes that from 2013 to 2016, the rankings of the air quality rankings of 74 key monitoring cities across the country, Shijiazhuang, Tangshan, Baoding, Hengshui, Xingtai, Handan and other cities in Hebei Province ranked the top ten consecutively. In addition, Shenyang City, Tianjin City, Taiyuan City, Shanxi Province, Xi'an City, Shaanxi Province, Zhengzhou City, Henan Province, and Jinan City, Shandong Province are also on the list.
In recent years, the problem of smog pollution in northern China has continued to plague the general public and affect their health. Therefore, air purification products have become essential appliances for home use. Air purifiers, also known as "air cleaners", air purifiers, purifiers, are capable of adsorbing, decomposing or converting various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.) , bacteria, allergens, etc., products that effectively improve air cleanliness. ,

Programmable DC Power Supplies
The CSP series Programmable DC Power Supply is upgraded and developed on the basis of iDealTek-Electronics' mature IGBT high frequency switching power topology and all-digital signal control loop. Featured with high precision, low ripple and fast response speed.
The Programmable DC Power Supply is different from the traditional DC power supply that can only control the output voltage and current values. The programmable DC Power Supplies can realize the programming of multiple parameters through adding the microprocessor unit with built-in control program, such as parameters like operating time, output rise time, protection response time, OVP and OCP etc. All can be set and programmed.
At the same time, the microprocessor unit also adds more functions to the power monitoring system, which can realize the query of the historical data of the test results, making the programmable DC power supply the best choice for laboratory test, production line manufacturing test, photovoltaic plate aging test and various cutting-edge applications with Programmable DC power supplies.
This series of Programmable Power Supplies have a total of 4 standard rated power levels, ranging from 1KW Desktop Programmable Laboratory power supplies to 3KW / 6KW / 10KW Rack-mounted Programmable DC power supplies. The maximum output voltage ranges from 600V to 1000V under different rated powers.
Beautiful appearance design with small and compact size, the whole series power supplies adopt silicone buttons, stepless knobs and LCD display on control panel layout. The output voltage, current, start / stop time, output rising rate, OVP, OCP and other parameter setting programming and reading of the Programmable Power Supplies can be easily and quickly completed through the front panel man-machine interface, up to 5 digits of high-precision programming and monitoring levels make the measurement results of the programmable DC power supply accurate and reliable, almost no need to use external power meters.
At the same time, the whole series of programmable DC power supplies are equipped with RS485 interface as standard, following the MODBUS-RTU international protocol, which can realize remote control programming, test results save and uploading to the master unit and status monitoring of the power supply.
