Supply DEHVP harmonic protector

Dongsheng Electric has years of technical accumulation and market experience in the field of power quality, and has developed and designed a series of harmonic protectors at the internationally advanced level. The harmonic protector is a high-tech product developed for precision instruments on the user side that are susceptible to malfunctions caused by various interferences. It can absorb high-frequency pulse spikes and high-frequency surge signals from the power grid and protect precision equipment, communication equipment, computer systems, and power supply equipment on the user side. Wireless equipment, thereby eliminating and reducing communication congestion, extending equipment life, improving power quality, and backing customers' clean energy. Harmonic protector functions:
◆Can actively absorb and control the amount of harmonics in the power grid.
◆Suppress high-frequency noise pulse peak surge current in the power grid.
◆Track the voltage and current waveforms at any time and correct the distorted waveforms.
◆Fast response speed and no switching delay.
◆Active protection for sensitive precision equipment at the end, and can be combined with active filtering products to form a comprehensive defense system.
◆Comprehensively overcome problems such as interference with electrical equipment caused by high-order harmonic pollution, without worrying about resonance with the system, and improve the safety, reliability and stability of system operation.
Application occasions of harmonic protector:
Places where a large number of computer switch communication equipment are used, such as the communication base station command center of the stock exchange, bank building, commercial office building.
Places where there are large-scale electronic dimming control systems, single-phase rectifier equipment, and large-scale power amplifier equipment, such as theaters, opera stages, stadiums, exhibition centers, etc.
There are strict cleanliness requirements for the use of electricity and it belongs to the premises of the unit that uses electricity, such as medium and large hospitals, government office buildings, public security and fire protection office buildings, etc.
The precision processing industry includes nano- and micron-level processing industries, such as the cigarette industry, film industry, pharmaceutical fine chemical industry, etc.
Port machinery, electrification, railway, non-ferrous metallurgical steel plant, etc.
