5U Industrial Intelligent Telecom Rectifier Solution AC to DC48V with Remote Management
Product Overview of 5U 18kW Intelligent Telecom Rectifier
The 18kW DC48V rectifier system delivers robust and uninterrupted DC power tailored for telecommunications, data centers, and industrial operations where system availability is non-negotiable. Operating from a 380VAC three-phase input, it supplies a stable and adjustable DC output ranging from –43 VDC to –58 VDC, nominally set at –53.5 VDC. Its advanced power conversion technology achieves better than 96% efficiency across the load range, making it an optimal fit for energy-sensitive and space-constrained installations.
