AC-DC Step-up Supply
Product Overview:
LCX Power YAS AC DC boost power supply is special purpose rectifier power supply designed for communication base stations and off grid no power areas.
It adopts two stage AC DC boost conversion and fully digital DSP closed loop control. It inputs wide range fluctuating AC voltage and converts it into stable high level adjustable DC output. Modular design supports parallel expansion.
It can cooperate with storage batteries to realize off grid continuous power supply for telecom equipment.
Featuring high efficiency, strong anti grid disturbance capability and wide environmental adaptability, it provides reliable DC power guarantee for remote communication sites, weak grid and no power regions.
Typical Applications：
4G/5G remote communication base station power supply in mountainous & pastoral areas
Off grid no power area telecom equipment DC power supply
Weak grid site communication station rectifier power supply
Meteorological, hydrological, environmental monitoring remote terminal power supply
Oil-gas field, border outposts, field monitoring equipment power supply
Distributed micro grid supporting DC boost rectifier unit
