節能省電器

綠色產業以及節能減碳，成為被大力推展的概念，因此，具有可節省電能功效的節能器，將為未來各種負載用電用戶必須使用的產品。

然而於上述節能器節省能源的同時，也須兼顧系統效能、提升電流被運用的功率、當電廠電流源不穩定或欠相時提供警示、監測電廠電流經處理時的電流及電壓顯示和提供該產品需要接受維修的指示訊號，而當負載用電端用電量大，需選擇三相的交流電源，在實用時，常發生故障或斷路，此外還需藉由輸入電壓範圍的擴大，與輸入電壓抗擾動能力的強化，來幫助提升電源供應器的整體運作效能。

利用三相交流電源操作之用電量大的設備，通常需要輔助電源模組，以負責提供控制電路較低的直流穩壓輸出。

此類節能器的規格要求遠比普通單相更為嚴格，由於額定輸入電壓更高，專為三相輸入而設計的設備即必須容忍更大的輸入電壓變動範圍。

Green Industry and carbon reduction, as was vigorously promoted the concept, therefore, can save energy with the energy efficiency of the device, for the next load of electricity users must use a variety of products.
However, in these energy-saving devices to save energy, but also must take into account the system performance, enhance current is the use of power, when the plant or less stable relative to the current source to provide alerts to monitor the current through the processing power of current and voltage display and need to provide the product signal maintenance instructions, and when the large electricity load electricity side, the need to select the three-phase AC power in a practical, often malfunction or break, in addition to the input voltage range by the need to expand, and input anti-disturbance ability to strengthen, to help improve the overall operation of the power supply efficiency.
The use of three-phase AC power supply operation of large equipment, typically require additional power supply module, the control circuit to provide a low DC output. Energy-saving devices such specifications are more stringent than ordinary single-phase, due to higher rated input voltage, for three-phase input device that is designed to tolerate a greater range of input voltage changes
