技术规格书 高性能、高可靠性电源产品 版本号： V1.0 5U200A 嵌入式电源 1 、 Overview The 5U200A embedded power supply is a new generation of highly reliable and high-performance communication power supply system designed by the company based on years of experience in development and online operation. The system configuration supports 1-4 rectifier modules that are hot-swappable. The system monitoring module has the function of battery management and power system monitoring. It can realize environmental monitoring by configuring appropriate sensors, and provide multiple sets of backup monitoring data. It can provide RS485 communication interface, which is convenient for remote monitoring and unattended.

This embedded power supply is mainly used in outdoor cabinets. 2 、 The main specifications of the product 3 、 Reference standards and specifications （1）YD/T 1058-2015 "High frequency switching power supply system for communicatio" (2) YD/T 731-2018 "48V Rectifier for Communication" (3) YD/T 585-2010 "Power Distribution Equipment for Communications" (4) YD/T 1051-2018 "General Technical Requirements for Communication Bureau (Station) Power System" 第 2 页 共 1 0 页 Maximum output power Input voltage range Output voltage Output current Rectifiers 12KW 85-300Vac 53.5V 200A RM4850*4(Fully equipped4PCS) Configuration AC input branch:

技术规格书 高性能、高可靠性电源产品 版本号： V1.0 5U200A 嵌入式电源 The power supply of the system is input by the single-phase AC mains through the AC input terminal to supply power to the rectifier module; the monitoring uses the input AC detection function of the module itself to detect the input voltage.

After the output of the rectifier module is concatenated, the negative pole is divided into three paths, one path is output to the negative input terminal of the DC load circuit breaker through the DC contactor of the primary power off, and the other path is output to the negative pole input terminal of the DC load circuit breaker through the DC contactor of the secondary power off, and then One way is output through the shunt to the negative input terminal of the battery circuit breaker. The DC contactor realizes battery over-discharge protection under the control of the monitor.

After the output of the rectifier module is connected, the positive pole directly goes to the positive input terminal of the DC load. 5 、 Environmental Conditions 第 4 页 共 1 0 页 Environmental parameters Environmental conditions Transport environment conditions Storage conditions Remark Project Parameter Unit Clim atic condi tions Temp eratur e Low temperature ℃ －5 －40 －45 It can start at full load at -40°C, and linearly derate 20% at +55~+65°C High temperature ℃ 40 70 70 Humi dity Low relative humidity ％ 5 / 5 / 3000~4000 derating output High relative humidity ％ 95 / 95 Condensation yes/no no / no Altitude m 4000 4000 Mech anica l stress condi tions Vibration Sine vibration: 5~9Hz:
