8000W 48VDC Power Rectifier 19 Inch Rack Mount Modular Rectifier
150A RS232 Ethernet
GPE48150G
Application
The 48VDC POWER RECTIFIERS are of rack mount modular rectifier for telecom applications with advanced battery monitoring and management system integrated.
The 48VDC POWER RECTIFIERS integrate high-efficiency modular
rectifiers into custom shelf and embedded rack systems featuring
remote monitoring, custom distribution centers, low voltage
disconnects (LVD), shunts, alarms, relays and enclosures for indoor
and outdoor applications.
The 48VDC power systems have the efficiency, features and reliability to match the needs of major telecommunication networks, and the AC power system converts AC input to -48VDC output. It mainly includes integrated power system.
The system is widely applied for outdoor telecommunication
cabinets. The system has high integration, high efficiency and high
reliability design, effectively helping customers to reduce energy
consumption and save footprint of the sites.
Features
