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
