ELECTRIC SHUTTER DEVICE
To provide an electric shutter device capable of opening/closing a shutter curtain at a specific speed even when a power supply with a different voltage is used.SOLUTION: The electric shutter device includes: a DC motor that drives a shutter curtain to open/close using a DC power; and a control unit that performs PWM control of the power supply from the power source to the DC motor. The control unit is configured to set the duty ratio in PWM control depending on the voltage of the power supply.SELECTED DRAWING: Figure 3
【課題】電圧が異なる電源を用いた場合にも、シャッターカーテンが一定の速度で開閉可能な電動シャッター装置を提供する。【解決手段】直流電流によってシャッターカーテンを開閉駆動するＤＣモータと、電源からＤＣモータへの電力供給をＰＷＭ制御する制御部と、を備える。制御部は、電源の電圧に応じてＰＷＭ制御におけるデュ－ティ比を設定する。【選択図】図３
