More Information
Summary:A power supply with electrical energy management, applied to variable speed blowing devices includes a rectification unit with a power factor correction function, a DC voltage stabilizing unit, a control unit, an input unit, a communication unit, at least one DC voltage regulator unit with an electrical energy measuring function, and at least one variable speed blowing devices. The rectification unit and the DC voltage stabilizing unit can use AC and DC as the power sources, respectively. The control unit utilizes the input information of the input unit and the electrical energy measuring information of the at least one DC voltage regulator unit to adjusts the output terminal voltages of the at least one DC output voltage regulator unit via applying a priority method, so that the load-shedding operation of the variable speed blowing device can be performed to meet the optimal regional demand control.
