When Parameter Min Typical Max Unit Notes atmospheric pressure 70 106 KPa Working temperature -25 55 ° C when the temperature is above 50 ℃, power systems work automatically derating Storage temperature -40 70 ° C Humidity 10 to 90% relative humidity, non-condensing. Noise 65 dB 0 3000 m altitude for operation in 2500m (5000 ft.) above, increased by 305m (1000 ft.) maximum operating temperature is reduced 2 ° C. Cooling power module comes with fan forced cooling of mechanical properties of the whole size 600mm × 600mm × 2000mm Total Weight ≤110Kg (with modules, cabinets + distribution) ● special specifications can be customized high-voltage DC power supply system is the latest development of a new generation of Flying science and technology, the large-capacity high-voltage DC power supply system. Using the latest high-frequency switching rectifier technology, dual DSP digital control, and active PFC, soft-switching technology, discrete enclosure design, a single cabinet can provide 100KW capacity, and through multi-cabinet and machine maximum 300KW capacity. System has high reliability, easy maintenance, energy-saving sleep, etc., to fully meet the power needs of the communications room, providing intelligent, green, green, safe, and efficient DC power source IDC data room equipment. Features: ◆ The rectifier uses active power factor compensation, power factor value of 0.99. ◆ AC input voltage of the normal operating range as wide as 90 ~ 290V. ◆ full bridge rectifier module adopts soft-switching technology, efficiency up to 90%. ◆ Improved battery management. There load power and battery low voltage protection (LVLD + LVBD) and the second lower electrical function, to achieve temperature compensation, automatic control are floating, automatic voltage regulator, battery capacity calculation, on-line battery testing capabilities. ◆ network design, offers a variety of communication interfaces (eg: RS485, dry contact), flexible networking real limit local and remote monitoring, unattended. ◆ complete AC and DC side mine design, adapt more thunderstorm. ◆ complete fault protection, fault alarm. ◆ Full front operation and maintenance, can be wall mounted to save space effectively. ◆ low radiation. The use of advanced EMC design, the rectifier can meet the "communication power supply equipment EMC limits and measurement methods" (People's Republic of China telecommunications industry standard YD / T983) in the conduction and radiation interference of the requirements. ◆ safe and reliable. System design in full compliance with safety standards EN60950 and GB4943 Tips more communication power battery products visit www.kfsfkj.com.cn www.sfdianyuan.com.cn
