Charger Model: 3634778 Features frequency machine is simple, there is a problem big a) the size of the input and output transformers; 2) for the elimination of large high harmonic output filter size; 3) transformers and inductors produce audible noise ; charging machine (6) 4) poor load and mains changing dynamic response performance 5) low efficiency; 6) Input no power factor correction, power grid more polluting; 7) the high cost DSE7310, especially for small capacity models, can not be compared with the high-frequency machine construction site distribution lines: the construction site using the main route 185 + 3 * 2 * 95 rubber cables laid along the wall, woodworking machinery, steel and other processing machinery extension cable with 3 * 50 + 2 * 25 wearing rubber cables buried pipe laying DSE7210, office lighting using PVC pipe threading done or plastic trunking wiring. Portable distribution boxes and switch boxes into, must qualify with a rubber insulated cables. When construction and renovation construction, Each unit building from the ground floor up every other layer to place a distribution box, power supply equipment for the construction of electricity.
