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
→外接发光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 - 90% (according to client's demand), then by-pass to battery voltage.
◆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 pretection
