Common Bridge Rectifier Testing Methods 1. Test the rectifier circuit, find the p terminal and N terminal of the DC power supply inside the inverter, adjust the multimeter to resistance X10, connect the red pen to P and the black pen to R , S and T. The resistance value should be about a few tens of
The role of the vehicle loop detector in the parking lot system In the parking lot system, to determine the role of the loop detector, we must first know the location of the detector installation. The loop detector is generally installed in the following four positions: 1. At the entrance tick
How to test the rectifier bridge is good or bad? With a digital multimeter diode file or pointer table 100 or 1000 files, measure the two AC input to the output of the rectifier bridge resistance, if it is an open circuit or short circuit that the rectifier bridge has been bad. The normal value shou
The role of rectifier bridge: the rectifier function of bridge rectifier is through the diode's single conduction principle to complete the work, to achieve the conversion of alternating current to direct current. Rectifier bridge is divided into full bridge and half bridge. The full bridge is conne
The principle of parking lot vehicle detector and ground sense coil 1. Working principle The ground induction coil vehicle detector is a vehicle detector based on the principle of electromagnetic induction. It usually embeds a toroidal coil under the road subgrade of the same lane, and passes
