Providing a Reliable Energy Foundation for Digital Transformation
ETP4860-B1A2 is an AC/DC embedded power system with excellent performance such as high power efficiency, intelligent battery management, remote management, wide range of AC/DC input voltage, etc. The system can configure 1U 30A high rectifier module, and provides 4kW output. ETP4860-B1A2 can be embedded in 19-inch rack or cabinet.
Core Advantages of ETP4860
Fully Modular Design, Flexible Expansion
Power modules and monitoring units fully support hot-swapping. Initial configuration is as needed; future business growth requires only adding modules to smoothly expand capacity without replacing the entire unit, supporting up to six 2000W rectifier modules.
Industry-Leading High Efficiency, Green Energy Saving
Utilizing Huawei's leading power electronics technology, efficiency remains as high as 96% even at 50% load. Compared to traditional power supplies, this can save considerable electricity costs for the site annually and reduce carbon emissions.
Multiple Protections, Intelligent Early Warning
Description: Features input over/under voltage protection, output overvoltage/overcurrent/short circuit protection, and module over-temperature protection. The intelligent monitoring unit monitors all parameters in real time and reports alarms via various methods such as dry contacts, SNMP, and RS485, enabling preventative maintenance.
Wide Environmental Adaptability, Stable Operation
Description: Supports a wide operating temperature range of -40°C to +75°C, adapting to harsh outdoor environments within data centers. High protection level ensures stable output under various climatic conditions.
