RC Absorption Circuit Module Relay Contact Protection Resistance Surge AC/DC 5V-400V Snubber Board
Description:
RC absorption circuit is also called RC Snubber
circuit. It is a circuit structure in which resistors and capacitors are connected in series and connected in parallel with switching devices. It is used to improve the voltage and current waveforms of electronic power devices when they are turned on and off. The RC absorption circuit module can prevent the induced electromotive force generated at the moment of turning on and off of the inductive load from causing damage to the switching devices such [...]
