AC-DC Remote Supply
Product Overview:
LCX Power-YAD AC-DC remote power supply belongs to communication base station & off-grid no-power-area series.
The system consists of local-end generator unit and remote-end converter unit. It adopts full-digital DSP control and isolated high-voltage transmission technology.
The local-end converts AC/DC input into isolated high-voltage transmission power, transmits power over long-distance cables; the remote-end converts high-voltage transmission power into standard AC or DC for field communication loads.
Modular design supports parallel capacity expansion. It solves power-access difficulty for remote sites without local mains.
Remote-end equipment can work without on-site battery, reducing field maintenance workload.
Featuring high transmission efficiency, comprehensive line protection and wide-temperature adaptability, it realizes stable long-distance power supply for scattered outdoor communication terminals
Typical Applications:
· Remote 4G/5G RRU pull away base stations, marginal communication stations
· Highway, tunnel, railway along line communication & monitoring equipment
· Mountain, pastoral off grid scattered communication sites
· Meteorological, hydrological, environmental monitoring outdoor terminals
· Border outposts, oil gas field unattended remote equipment
· Indoor distribution system, WLAN AP, ONU remote power supply scenario
Technical Features：
1. System Topology & Control
Composed of local end power generator and remote end converter.
Isolated high voltage transmission architecture, full digital DSP closed loop control.
Modular power unit, multi module parallel expansion, supporting multi load simultaneous power supply.
2. Electrical & Transmission Performance
· Local end input: Wide range AC / DC dual mode input
· Transmission: Isolated high voltage long distance transmission, long transmission distance, low line loss
· Remote end output: Optional standard AC220V or DC24V/48V communication voltage
