Be suitable for the development of the structure of double district area broadband network and specialized for meeting the good installation of forward – end room equipment. According to the thought of module design of two power modules and eight function modules in 19” 5U height criterion machinery to supply an intelligent assembling control system which monitor the practical parameter and give the automatic warning signal when problems to be made suddenly. The structure of two power supply hot backup coordination with warm system controlled by micro computer to improve the reliability of system. Set with RS-485 and RS-232 web tube transmission connector, assemble controlling conveniently. It is the first-choice of Bi- directional HFC broadband network

The new style of Switching Power, reasonable volume, Low power consumption, high efficiency of transformation and Power output; There are two WOS-2001 Module at max under hot backup operating.
