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
→外接发光led及导线
◆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%, then by-pass to battery voltage (according to customer's demand).
◆optional with the function or accessory as follows:
→extrenal mosfet version
→auxiliary led and wires
