DC-DC Step-up Supply
Product Overview:
LCX Power-YDS DC-DC boost power supply belongs to communication base station & off-grid no-power area series.
It adopts isolated boost topology and full-digital DSP closed-loop control. It converts low-voltage fluctuating DC from battery bank, solar array into stable high-level adjustable DC output.
Modular design supports multi-unit parallel expansion with active current sharing function. It can cooperate with photovoltaic, storage battery and diesel generator systems.
It features high conversion efficiency, low output ripple, strong anti-disturbance and wide-temperature environmental adaptability.
It is widely applied for remote communication sites, off-grid micro-grid and field monitoring equipment, providing reliable high-voltage DC power supply solution.
Typical Applications:
· Remote 4G/5G communication base station high-voltage DC power supply
