Customized 5.22kw DC Power Supply Cabinet for Basement Station Telecommunication
Overview of 5.22kw DC Power Supply Cabinet
Designed for outdoor telecommunications applications, the 5.22kW DC Power Supply Cabinet provides uninterrupted power protection, shielding customer equipment from both electrical disturbances and severe environmental conditions. The cabinet accommodates telecom equipment occupying up to 16U of rack space and simultaneously supplies power to both active and passive telecom devices. Equipped with a DC 48V rectifier system, it delivers up to 5.22kW of power distribution for internal telecom equipment and associated protection systems. A 500W air conditioner combined with thermal insulation cotton effectively dissipates heat generated by both the equipment and the surrounding environment, maintaining optimal operating temperatures inside the cabinet.
The cabinet offers an integrated and flexible power supply that provides a reliable DC power to telecom base stations, data centers, and industrial facilities. Operating from a single-phase 220V AC input, it provides a tightly regulated DC output adjustable between –43V and –58V (typically set at –53.5V), while ensuring comprehensive protection for the power system. With a maximum output capacity of 5.22kW, the system achieves conversion efficiencies exceeding 96% across most of its load range, significantly lowering energy consumption and reducing associated cooling costs.
