● 控制器直接从 AC 插座获取电流 ，转换成低电压输出， (HI: DC30V) 或 (LOW: 约 DC20V) 供给直流电动螺丝刀。
●具有**、旋转噪音小等特点。
● 为保证**作业，请使用与HIOS**电动螺丝刀配套的HIOS**专用控制器。
●宽电压输入 (AC100 ~ 240V)，稳定供给电源。
●Exclusive controller converts the electric current from AC outlet (on the primary side) to low-voltage output (HI: DC30V or LOW: about DC20V) to supply it to the screwdriver.
●Safe and quiet rotation.
●Please always use HIOS screwdriver in combination with HIOS controller for safe screw tightening.
●Stable power supply with multiple inputs (AC100V to 240V).
