产品特征Features

◆本开关结构紧凑效率高,大面积的固定式散热片为开关的安装提供方便.开关内部为单极常开带直通接点结构,通过改变输入脉冲的占空比来控制场效应管的输出电压,而实现电子调速功能.
◆开关输出端的平均电压为总电压的8-50%至8-90%,也可以按客户要求进行定制,开关按到底由直通接点接至电池端电压.
◆可选带以下功能或附件:
→外置MOS管
→带软胶扳机
→外接LED及导线
→外接电池温度检测导线
→智能调速功能,可带软启动,欠压保护,过流保护,电池过温保护
◆The switches combine compact size with high performance, a wide scope of heat sink for MOSFET and further options provide easy to mount solutions. They employ SPST-NO with by-pass contact, integrated PWM (Pulse Width Modulated) electronics in
various dimensions.
◆Average duty cycle of motor voltage 8 - 50% to 8 - 99%, then by-pass to battery voltage (according to customer's demand).
◆Optional with the function or accessory as follows:

→External MOSFET version

→Trigger covered with rubber

→Auxiliary LED and wires 

→Auxiliary wire for temperature test

→Multi-function, optional soft start, under-voltage protection, over current protection, battery temperature protection
