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; high 7) costs, especially for small capacity models DSE7320, can not be compared with the high-frequency machine charger Model: 21429783 use of premises (1) The machine should be placed in a dry place DSE5220, avoid the heat, dust and corrosive gases. (2) Confirm the rated input voltage of the machine with the grid voltage used are the same. (3) In order to ensure the normal operation of this machine DSE5210, to keep the air clear. Around the unit for at least 750px space and to check the vents for blockage. (4) the charger and the battery placement, as shown below: image above: a-- electric vehicles A, B necessary space around at least 0.6 meters; b-- be charged a minimum distance between the battery and charger 1 m; c-- charger distance to flammable materials shall not be less than 2.5 m; distance d-- charger to explosive materials shall not be less than 5 m; e-- charging room interior height (depending on the vehicle) not less than 2 m.
