Распределительные щиты интеллектуальной связи

Characteristics: This DC distribution panel is particularly designed for the exchanging or communication equpiments of large capacity customers and switching station .Suitable for the communication places with centralized monitoring ,remoto maintainance and unmanned operation. DC fuses with auto-reset function or porcelain fuses,reliable and easy to use. Light or sound alarm ,alarm reset automatically or manually ,with date record (yy-mm-dd-hh-mm-ss) ,easy to maintain,alarm can be reset through computer system. Through the interface-RS232,RS485,MODEM,the flexible connection with remote monitoring system can be achieved ,improving the management efficiency greatly. This cabinet can be grounded well.Frame, DC power and DC power is separately grounded,all grounding insolates from others.Able to meet specification defined in YD/T939-1997. Main technical performance: nominal input voltage : DC-48V Real input voltage : DC-40V -57V Input capacity: 1000A Input type: copper bar or cable ,from top or side Output type: copper bar or cable ,from top or bottom Color:Positive(+)Red, Negative(-)Blue Analog measuring : voltage×2,current×6 Digital test:main/stand by ×8,main/stand by switch×32 Measuring precision: voltage±1% current±2% Cooling:natural cooling Electricity resistance: AC1000V/5mA/1min Insolation resistance: ≥30MΩ/500V Alarm: light and sound Ambinent temperature:5 40oC Relatively humidity:≤85%(30oC)
