Charger Model: 3634778 Features frequency machine is simple DSE7110, big problem is a) the size of the input and output transformer; large output filter size 2) for the elimination of high harmonics; 3) produce audio transformers and inductors noise; charger (6) 4) and mains load changes the dynamic response of the poor performance of low 5) efficiency; 6) Input no power factor correction, power grid more polluting; high 7) costs, especially for small capacity models, can not be compared with the high-frequency machine charger Model: 21429783 fast charger prospects from prospects of development, the next step is to replace the lead-acid battery lithium battery and a capacitor battery DSE7320, two batteries feature is adapted to high current fast charge (in theory DSE5120, the capacitor battery, regardless of how much battery capacity, as long as the charger and the battery capacity support, the use of wire cross-sectional area is large enough to add just a few seconds to complete electric task), just put control controls lead acid battery charging off without, to give more than two batteries.
