PROBLEM TO BE SOLVED: To provide a power supply device for an electric fence in which a system capable of applying a proper voltage according to the change of the voltage is easily feasible at low cost.SOLUTION: A power supply device for an electric fence comprises: a power supply a voltage generator electrically connected with a wire rod, and applying a voltage to the wire rod and a micro controller interposed between the voltage generator and the power supply. The micro controller measures the voltage supplied from the power supply, and has the function of interposing the time when not storing electricity during storage time of a predetermined capacitor when the measured voltage is higher than a predetermined value, and of interposing the time when not performing electric storage in addition to the storage time of the predetermined capacitor and not applying electric current when the measured voltage is lower than the predetermined value.COPYRIGHT: (C)2015,JPO&INPIT【目的】電圧の変化に応じて適正電圧を印加することが可能なシステムを低廉容易に実現可能な電気柵用電源装置を提供すること。【構成】電気柵用の電源装置において、電源と、線材と電気的に接続されると共に、同線材に電圧を印加する電圧発生器と、該電圧発生器と電源との間に介在されるマイクロコントローラであって、前記電源から供給される電圧を測定すると共に、当該測定した電圧が所定値より高い場合には、前記所定の蓄電器の蓄電時間中に蓄電を行わない時間を介在せしめ、所定値より低い場合には、前記所定の蓄電器の蓄電時間に加えて蓄電を行わず、且つ、電流を流さない時間を介在せしめる機能を有するマイクロコントローラとにより構成した。【選択図】 図4
