5000W Hu800 power frequency machine power

The power machine is more than high frequency machine is expensive, it is because the power machine than high frequency machine more than one output isolation transformer, but the transformer is not like power machine advertised anti-jamming and buffer load, the transformer is the power machine is essential, as the local machine power frequency high frequency machine, because of the transformer the power machine is essential, he only plays a role in boosting, is the process rather than the high frequency machine, high frequency machine is through the bridge block boost performance than the power machine stability, low cost, small volume, while the output power factor and safety are greatly improved.
