    Which current sensing switch is good?

    Column：Current sensing switch Function：Set switch action value For example, if the piercing current exceeds 3A, an output switch signal is generated. (Example of normally open switch) 1. Thread one of the phase wires through the switch hole. 2. Adjust the piercing current to 3A. 3. If the red light is on at this time, it indicates that the piercing current has exceeded the action threshold, which means that the threshold is less than the piercing current and needs to be rotated in the H direction. Rotate until the green light is on, and then the red light will turn on to lock. That is, the switch action threshold has been set to 3A. If the green light is on at this time, it indicates that the piercing current is less than the action threshold, which means that the threshold is greater than the piercing current and needs to be rotated in the L direction Rotate. When the red light is lit during rotation, and then the green light is lit upon returning, it indicates that the switch action threshold has been set to 3A.

    Introduction

    Guangdong Fearlie (Fengli Electronics), a local factory in Foshan, is also a brand with significant shipments of this passive AC current sensing switch in China

    Application examples:

    When the piercing current exceeds the set value, the relay activates. When the current drops below a certain level, the relay resets. This frequent activation can facilitate automatic switching in industrial automation, and it can also provide a switch signal to the PLC

    It can be used as a linkage switch, with the action of the linkage relay (the relay controls another device that requires linkage) monitoring the simultaneous start of the equipment (perforation line equipment) and the output control device of the relay

    , and stop 3. It can be used for current overload protection. When the current through the current transformer switch exceeds the rated current, the contactor is disconnected to monitor whether the equipment is working properly
