1U 48V 100A Telecom DC Power System (ETP48100-B1)
Compact 1U Design: Ultra-thin 1U rack structure (45mm height), dimensioned at 45×315×415mm and only 7kg in weight, saving cabinet space for dense deployment.
Dual AC Input Adaptation: Supports 100-120V and 200-240V AC input, with a wide operating range of 85-290V AC, adapting to various global power grid environments.
High Efficiency Performance: The matched R4850G2 rectifier module achieves up to 96% conversion efficiency, low heat generation and low power consumption for long-term operation.
Modular Hot Swap: Rectifier modules support hot plug and replacement. No system shutdown is required during maintenance, effectively reducing service downtime.
Reliable Heat Dissipation: Built-in fan forced convection cooling system to ensure stable full-load operation and extend product service life.
Multi-circuit Output: Multiple DC load output ports to supply power for multiple communication devices simultaneously, flexible for system configuration.
Comprehensive Protection: Integrated overvoltage, overcurrent, short-circuit and over-temperature protection, plus surge resistance (2kV differential / 4kV common mode) to protect terminal equipment.
Strong Environmental Adaptability: Works stably at -33℃ to 55℃, storage temperature ranges from -40℃ to 70℃, and can operate normally below 3000m altitude.
Certified Quality: Passes CE and ISO certifications, compliant with international telecom equipment standards; custom logo service is supported.
