Configure the UPS front room
time2012/06/06
Front room is the heart wins cable television system, in order to ensure their job stability, usually selected three-phase input single phase output type. Rated power is generally l OkVA of online UPS power supply to the launch of the new wing of the device IGBT module, with its own external battery pack can increase or decrease indemand for UPS hardware laid the foundation of the long delay. This shows the UPS circuit can accurately reflect the operational status of equipment and related data, but also has a powerful self-diagnostic function, for the satellite receiver unit,modulator group, the light emission unit, network switches and other front-endequipment to provide uninterrupted, high-purity of the power supply. Howard countyis not connected UPS front room before every trip at power stations, the Catv Trunk Amplifier power supply and power amplifier front-end signal will be interrupted. Even if the city and county programs have several sets of fiber optic cable transmission with batteryprotection, but also because the engine room and other equipment off the modulatorcause program interruption, no regional power or CATV user can not receive cable television programs, users are very dissatisfied. Since the UPS front roomconfiguration, even at the power station, cable TV still normal transmission, thus improving the user satisfaction of the television.
Carried out in a number of multi-city interactive services, the front room of the powersystem reliability requirements are higher, generally can be used hot or UPS in parallel redundant backup connection to connect. Parallel connected UPS system not only improves reliability, but also increased the load capacity.
