- 外部に接続された負荷機器を動作させるための電力供給を制御するアダプタと、前記負荷機器の動作を指示する第1の制御指示を受け付ける操作指示受付部と当該操作指示受付部により受け付けられた第1の制御指示を無線通信によって前記アダプタへ送信する端末側無線通信部とを備えた制御端末と、を備えた負荷制御システムであって、
前記アダプタは、
前記負荷機器に電源電圧を供給する電力線から電源電圧を受電する第1及び第2の接続端子と、
前記第1及び第2の接続端子から前記負荷機器への電力供給を制御するアダプタ側スイッチ部と、
前記第1及び第2の接続端子を介し、かつ前記負荷機器及び前記アダプタ側スイッチ部を介することなく前記電力線に接続され、当該電力線を用いて電力線搬送通信を行う電力線搬送通信部と、
前記端末側無線通信部との間で無線通信を行うアダプタ側無線通信部と、
前記アダプタ側無線通信部により受信された前記第1の制御指示と前記電力線搬送通信部により外部から前記電力線を介して受信された第2の制御指示とに応じて前記アダプタ側スイッチ部のオン、オフを制御するアダプタ制御部と、
前記第1及び第2の接続端子から前記負荷機器及び前記アダプタ側スイッチ部を介することなく電源電圧の供給を受けて、前記電力線搬送通信部、前記アダプタ側無線通信部、及び前記アダプタ制御部の動作用電源電圧を供給する電源回路とを備え、
前記第1の接続端子は前記電力線における一方の相と接続され、前記第2の接続端子は前記制御端末を介して前記電力線における他方の相と接続され、
前記制御端末は、
前記端末側無線通信部を動作させるための動作用電力を供給する第1の電源部を備え、
前記電力線における他方の相と前記アダプタとの間には、前記第1の電源部と手動式の端末側スイッチ部との直列回路が介設され、
前記第1の電源部における入力インピーダンスは、前記端末側スイッチ部がオンされている場合に前記直列回路を介して前記アダプタへ供給される電流を、前記負荷機器の動作電流以上とするべく低インピーダンスにされていることを特徴とする負荷制御システム。 - 前記制御端末は、前記端末側スイッチ部と並列に接続された、前記端末側無線通信部を動作させるための動作用電力を供給する第2の電源部をさらに備え、
前記第2の電源部における入力インピーダンスは、前記端末側スイッチ部がオフされている場合に前記第2の電源部を介して前記アダプタへ供給される電流を、前記負荷機器の動作電流未満とするべく高インピーダンスにされていることを特徴とする請求項1記載の負荷制御システム。
