AC Remote Power Slave Unit
Product Overview:
LCX Power-YAX AC remote-power-supply remote-end unit belongs to communication base station & off-grid no-power-area series.
It is the matched receiving and step-down converter unit for AC remote power-supply system, working cooperatively with LCX Power-YAS local-end unit.
It adopts full-digital DSP isolated AC step-down sine-wave restoration topology. It receives high-voltage isolated AC transmitted over long-distance cables from local-end unit, and converts it into standard pure sine-wave AC output for outdoor AC-type field loads.
Adopt outdoor dust-proof & water-proof integrated enclosure, compact structure, supporting pole-mount and cabinet-mount installation.
Built-in hardware fault-isolation circuit; fault of single remote-end unit will not affect other units on the same transmission line.
It avoids difficulty of on-site mains access and reduces workload of field battery deployment & maintenance for scattered outdoor AC equipment in mountainous, pastoral and off-grid regions.
Typical Applications:
· Highway, tunnel, railway along-line surveillance camera, lighting, AC monitoring equipment power-receiving terminal
· 4G/5G pull-away base station AC peripheral equipment power supply point
· Mountainous, pastoral, island scattered outdoor AC-type loads
· Meteorology, hydrology, environmental-monitoring outdoor AC instrument terminals
· Oil-gas field & pipeline unattended AC monitoring equipment power-supply terminal
· Outdoor security monitoring, industrial sensor AC centralized remote-power-supply projects
Technical Specifications:
1. Topology & Mechanical Structure Isolated AC step-down sine-wave restoration topology, full-digital DSP closed-loop control. Outdoor integrated enclosure with IP65 protection grade. Support pole-mount and cabinet-mount installation. Independent hardware address, multiple remote-end units can be connected on one transmission line.
2. Electrical & Output Performance Wide-range isolated high-voltage AC input, adapt to voltage drop of long-distance transmission cables-Standard pure sine-wave AC output Single-unit conversion efficiency ≥93%-Output voltage precision ≤±0.5%FS, THD ≤3%, low waveform distortion-Fast dynamic response, restrain output fluctuation caused by line voltage variation.
3. Fault Isolation & Line-adaptability Built-in hardware fault-isolation circuit. When internal short-circuit or abnormal fault occurs, it automatically isolates itself from transmission line without interfering other remote-end units. Equipped with surge lightning-protection module and line leakage protection. It can automatically resume operation after fault removal.
4. System Compatibility Pure passive receiving & AC step-down converter, no local battery required on-site. Perfectly matched with LCX Power-YAS AC remote-power-supply local-end unit. Compatible with mains, wind-solar hybrid, battery-backup power-supply mode on local-end side.
5. HMI & Communication Interface Local LED status indicator lights for running and alarm information. Optional external display module. Standard RS485 interface, Modbus protocol. Upload operating data and fault codes to local-end unit, realizing remote status monitoring and fault location for each field power-supply point.
6. Environmental Adaptability Natural convection heat dissipation. IP65 dust-proof & water-proof enclosure with anti-corrosion surface treatment. Operating temperature:-40℃ ~ +65℃. Adapt to open-air outdoor, mountain, coastal, highway and other harsh field environments.
