The characteristics of the industrial frequency machine are simple. The problem is that the input and output transformers are large;Charger the output filter used to eliminate high-order harmonics is large; the transformer and the inductor produce audio noise;Charger the dynamic response performance to the load and mains changes is relatively good. Poor; low efficiency; input without power factor correction, serious pollution to the grid; high cost,Charger especially for small-capacity models, can not be compared with high-frequency machines.
Normal working conditions: The altitude does not exceed 2000 meters;Charger the surrounding medium temperature is not higher than +40℃ and not lower than -10℃; Charger the relative air humidity is not more than 85% (when the medium temperature is 20℃±5℃);
A place without conductive dust; an environment with no explosion hazard;Charger an environment that does not contain gases and vapors that can corrode metals and insulation; where there is no rain and snow attack;Charger where the vertical tilt is not more than 5 degrees and there is no severe vibration and impact .
