Charger Model: 3803639-frequency and high-frequency machine machine reliability ratio, high frequency machine unreliable is untenable, the world-renowned manufacturers in the charger on technology selection and development trend of the future are based on the high frequency of absolute main direction, 30KVA and below the machines are mainly high frequency machine, this dynamic, fast response, high energy density, small size, low noise ESD5330, low prices have a great relationship, especially with high-frequency high-frequency machine load Machine can be done active input power factor correction ESD5221, truly represent the future development trend of green power charger Model: 21429783 The machine has an automatic equalization charge are filled manually preset are two ways to charge for users to choose. You can not use a balanced approach each charge ESD, otherwise it will affect the normal life of the battery. Generally, only a month of storage battery 1 to 4 times a balanced charge. a, automatic equalizing charge the battery fully after shutdown, such as battery and mains power remains with the native contact ESD5520E, then 15 hours later will automatically balancing charge, were charging time is 3 hours, were automatically shut down after the end of the charge. ESD5522E, ESD, faithful electromechanical provided by the Dongguan City, South City Zhongxin Electrical and Mechanical Services Department.
