Features: Detect the input current. If the input current exceeds the set value, control the output power off Used for over-current protection of motor stalling, excessive current protection, etc. Start for 2 seconds; Filter out the large fluctuation of current caused by instantaneous electrification of inductive load of motor; Convenient for direct control of equipment switching,automatic control. High quality Electronic components, stable working performance Specification: Product model: YFI-1 Setting range: 0.01A-10A General supply voltage: DC7-24v Wiring instructions: pluggable wiring: input how many volts, output is how many V, output control positive pole on and off. Setting instructions:+ : the upper limit of current increases, - : the upper limit of current decreases.When the output is suspended; Meanwhile, press and hold both"+, and-" : error calibration, current return to zero. Weight: Approx.51g/1.8oz Package list: 1 x Current detection Module 1、Detect the input current. If the input current exceeds the set value, control the output power failure. 2、Used for over-current protection of motor stalling, excessive current protection, etc. 3、Start for 2 seconds; Filter out the large fluctuation of current caused by instantaneous electrification of inductive load of motor; 4、Convenient for direct control of equipment switching,automatic control. 5、High quality Electronic components, stable working performance
