Relay concept and principle The relay usually refers to the latching relay, which is the kind of mechanical action relay. The essence of the relay is to use a loop (usually a small current) to control the on and off of another loop (usually a large current), and in this control process, two The circ... read more
⑴Simple judgment method of relay performance Turn on the ignition switch, and then use your ears or stethoscope to listen to whether there is a sound in the control relay, or feel whether the relay is vibrating with your hands. If so, it means that the relay is basically working normally, and the el... read more
The role of current transformers: the currents vary greatly in the lines of power generation, transformation, transmission, distribution and power consumption, ranging from several amperes to tens of thousands of amperes. In order to facilitate measurement, protection and control, it needs to be con... read more
The car latching relays is broken. The relay is an important part of the car. If the starter relay is broken, the car will not start. If the ignition switch relay is broken, the car will not start, and if the power window relay is broken, the power window of the car will not be able to rise and fall... read more
We should all be aware of the role of the 100A UC3 & ROHS COMPLIANT TWO-PHASE RELAY. As long as a certain voltage is applied to both ends of the coil, a certain current will flow in the coil, which will produce electromagnetic effects. The armature will overcome the pull of the return spring und... read more
