DC overvoltage relay

We often use special DC relay to control low powered DC motor in cars.

在汽车中 ,常常采用特制直流继电器控制小功率直流电动机正、反转。

An experimental investigation of influencing factors on contact bounce of DC relay by using a high-precision laser displacement sensor was presented.

利用高精度激光位移传感器测量直流继电器触头弹跳的特征参数,通过实验研究其影响因素。

The high frequency electromagnetic value\'s driving circuit by DC relay is replaced by TIP122,therefore,the circuit is become simple and the cost cheap.

使用达林顿三极管TIP122替代直流继电器驱动高频电磁阀,使得电磁阀驱动电路简单,成本低廉。
