5,16 V voltage load short-circuit protection. When the load short-circuit voltage 16V , 16V voltage disappears , for the protection circuit D811 16V supply voltage disappears or is very low , D811 off into the protected status .SdFservice manual download site

6 , the field current protection circuit . Sampling resistor R476 and Q454 field composed of an overcurrent protection circuit , resulting in failure of the output circuit current spot is too large , the voltage drop increases R476 , when above 0.7V, Q454 is turned on , a very high level of c , Q805 through R554 makes conduction .SdFservice manual download site
