ZXDU58 B900 900A -48V DC Embedded Power Module for Data Center Server Power Backup

ZXDU58 B900is a high-performance -48VDC embedded switching power supply developed by ZTE, tailored for the power supply needs of communication equipment.Adopting a standard 19-inch rack design with a 3U compact height (482.6×132.5×319mm, W×H×D), it integrates AC/DC power distribution, rectifier modules, and an intelligent monitoring unit into one body, with a full-configured weight of only 18.9kg.

1.High Efficiency& Energy Saving:The rectifier module adopts advanced soft-switching technology and active PFC technology, achieving a peak system efficiency of ≥93% and an input power factor of ≥0.99 under full load.The intelligent sleep mode reduces standby power consumption, saving up to 10% energy compared to traditional power supplies.
2.Wide Adaptability:With an ultra-wide input voltage range of 85VAC~300VAC and a working temperature range of -20?~65?, it performs reliably in harsh grid conditions and extreme outdoor environments, eliminating the need for additional voltage stabilization equipment.
3.Intelligent Management:Equipped with RS232/RS485 communication interfaces, it supports telemetry, telecommand, and telesignalization (three-remote functions) for remote monitoring.The built-in smart battery management system automates charging modes and implements primary/secondary power-down protection to extend battery lifespan.
4.High Reliability& Safety:Equipped with C-level + D-level surge protection (≤40kA) and comprehensive protection functions against overvoltage, overcurrent, short circuit, and overheating.The rectifier modules support hot-swapping, enabling maintenance without system shutdown, with a mean time between failures (MTBF) of ≥2.2×10? hours.
5.Compact& Maintenance-Friendly:The 3U compact design saves 50% cabinet space, making it ideal for integrated cabinets.The drawer-type module structure and LCD man-machine interface simplify installation, parameter setting, and fault diagnosis.

1.Communication Base Stations:Suitable for 4G/5G wireless base stations, providing continuous power for transceivers, baseband units, and other core equipment.
2.Data Centers& Computer Rooms:Powers servers, storage devices, and network switches in small-to-medium data centers, ensuring uninterrupted operation of data processing systems.
3.Access Networks& Transmission Equipment:Applied in FTTX OLT equipment (C300/C320/C600), microwave communication devices, and satellite ground stations, adapting to distributed network deployment.
