POWER SUPPLY DEVICE

摘要

The purpose of the present invention is to make a power supply device comprising: a power input unit which receives power from the outside; a power converting unit which converts the power received by the power input unit into power corresponding to AC power environments; a transformer unit which receives the power converted by the power converting unit and controls and outputs the voltage of AC power; and a rectifying unit which converts the AC power output from the transformer unit into DC power. There is an effect of conveniently converting the AC input power using the power converting unit with a card form. As a result, there are effects of protecting equipment of a load side and preventing additional damage to the power supply device.
