The ETP48400-C3B1 are embedded power systems that convert AC power into DC power. They supply -48 V or -57 V constant voltage to telecommunicationsequipment. The maximum capacity of the ETP48400-C3B1 is 24 kW, and the maximum capacity of the ETP48400-C3B2 is 18 kW. They apply to 5G sites as well as capacity expansion and reconstruction of existing sites. The intelligent power distribution unit DCDB48-200-16B/DCDB48-200-16B-XXX and lead-acid battery box DCDB48-400-4C are optional components.
ETP48400-C3B1 is a new type of embedded power supply developed by Huawei.
Architecture design, small size, high power density (capacity up to 24kW, 3U height), power distribution
Can be modularly expanded, with features such as convenient installation and maintenance, full digitalization and full intelligence, suitable for
Used for capacity expansion and reconstruction of existing wireless sites, new 3G/4G wireless sites and new 5G wireless sites
Waiting for the scene.
Features:
*l Small size, 3U height, high power density
* Innovative architecture design supports modular expansion of power distribution
* Wide AC voltage input range: 85VAC~300VAC
* Supporting intelligent power distribution unit, supporting multi-level power-off management, matching 5G business network diversification
* Supporting Huawei BoostLi lithium battery supports -57VDC constant voltage output, meeting 5G high power AAU pull Far power demand
* Intelligent peak-shaving, site-free electric power renovation: When the peak load exceeds the mains input power, the power
* The source controls the battery discharge, and the mains and the battery cooperate to supply power to the load, eliminating the mains supply peak
Value, reduce the investment required for the expansion of the city's power capacity
* Intelligent peak mismatch, release site potential: adaptive adjustment of power grid, make full use of peak and valley electricity price difference,
Reduce site electricity consumption
* Intelligent management, remote online maintenance, reducing the number of drop-off times and maintenance costs
Application:
* Capacity expansion of existing wireless stations
* New 3/4G wireless site
* New 5G wireless site
