II) the characteristics of the source cabinet PS48600-3/2900:PS48600 source system-3/2900 are set in areas where sudden decline voltage as the BTS, switchboard are small, satellite communications and data communications.The source system can install, operate and maintain easily. The small cable on/off AC/DC is connected to the source from the top down or from the bottom up. The characteristics: The rectifier (rectifier) using techniques of PFC (Power Factor Compensation) compensation coefficient, source can be up to 0.99. AC input voltage ranges: + From 125 285V used for automatic conversion system.+ From 85 290V used for converting the system manually. Technical performance conversion software can be set to 90%.With EMC's design features, the rectifier is designed in accordance with international standards such as CE and NEBS. The rectifier can add hot, giant forecast or what less than 1 minute. Protection against excessive pressure for both hardware and software. Average battery management system closely: LLVD management, BLVD, clearing heat, adjust the voltage automatically limits the line, calculate the amount of batteries and test batteries. Provides more ports port communication: RS232M, modules ... allows dynamically network management and remote management. AC and DC dog of lightning. Detection and warning of errors. Source cabinets can hang on the wall. The casing above the grid and prevent dust.III) major equipment: Rectifier R $ *-2900 (rectifier): Power indication. Fault indication. Protection indication. I/O terminals. Positioning pin. Specifications: Are divided according to the PFC circuit. Limited control voltage: 90 ~ (170V-180V) ~ 290V. Foldback short-circuit protection Ics < 1/3Io. Can add hot (hot pluggable), input/output has kicked soft spots. Warning protection, error alerts. The limit line, under the control of the monitoring module. Monitored and controlled activity status by the CPU in the rectifier. Independent operation without supervision module. Net stop Bush, radiator fan manually adjust speed, easy cleaning and maintenance.
