product description

MAPF active power filter, Chengdu Mellon Electric Co., Ltd. is the latest technology and research results at home and abroad, independently developed a dynamic suppression of power harmonics, compensation reactive power of the new power electronic equipment. Applicable to 380V × (1 ± 20%) voltage system, is the perfect solution for harmonic control. The device adopts the current advanced dynamic suppression of power harmonics, compensates the reactive power way to eliminate the power grid harmonics, real-time detection by the non-linear load current waveform, separates the harmonic component, will reverse, the size, The opposite direction of the harmonic current into the power grid, to achieve filtering harmonic function. In addition, the device can also provide reactive power compensation current, used to improve the power quality, improve the efficiency of power supply equipment, reduce power loss.

 

Product use

Chengdu, a commercial plaza to "experience-based business" as the core in the transmission of a city brand "young, fashion, trend, taste," the core content of its overall positioning as "JOY CITY JOY PARK domestic first experience recreation tide shopping Park ", the project is located in a road in Chengdu, with a total construction area of 400,000 square meters, including Grade A boutique office buildings, large shopping centers, theme blocks three parts.
