24U Outdoor Telecom Rectifier Cabinet with 12kw DC Power Distribution
Product Overview of 24U Outdoor 12kw DC Power Cabinet
The ET-series 24U telecom power cabinet is an outdoor cabinet which can protect customer’s equipments from damage and extreme weather conditions. Lead-acid battery and 24U telecom equipments can be accomodated inside the cabinet. The cabinet can provide power for active telecom equipments and passive telecom equipment at the same time. With a DC48V rectifier system, the cabinet is able to provide 18kw power distribution for telecom equipment inside the cabinet and protection, while controller can monitor and management equipment situations and events online.
The cabinet Integrated provides a high-density, carrier-class power platform engineered to deliver uninterrupted DC power for telecommunications central offices, mid-to-large data centers, and industrial facilities. Operating from a three-phase 380V AC input (with no internal circuit breaker), it supplies a precisely regulated DC output adjustable between –43V and –58V, typically set at –53.5V. With a maximum output of 18kW, the unit achieves conversion efficiencies exceeding 96% across most of its operating range, significantly reducing energy consumption and the associated costs of cooling.
