施耐德SPRM36BP-9AH 36V外接电池包适用于SPRM1KL报价
1, but when the mains power iscut off, K1 is disconnected, Lesendelli County input voltage +24Vis unchanged, N continues to pull, K2's self-locking action, +24Vis still high load sent to the converter.
2, after a period of time, thebattery voltage began to decline, Vo followed the decline, V1conduction weakened, V2 increased.
3, when the edge rises to anumber of values (that is, the battery voltage drops to 22V), thenV2 exits saturation into linear amplification, and V3 rapidlydecreases.
4, V3 through R7 feedback toabout V1 base, so that V2 continues to rise, forming this avalancheprocess.
5, V3 quickly cut off, M isdisconnected, the battery is sent to the rectifier in my opinion+24V DC is cut off, the converter stops working, K2 isdisconnected.
