When the switch is on instrument is not getting supply. But the same circuit is working fine with the general DC power supply(0-30V). Please tell me where i have done mistake.... Thanks Sree Last edited: Apr 24, 2010

S sreekanthm New Member Apr 24, 2010 #3 Hi Diver, Thanq for the reply. Regarding the battery protection circuit i do not know...i have to find it out from the manufacturer/designer.... Swith is working and it has rating up 10Amps and the circuit consumes 2.5 Amps only But while connecting to the DC power supply i am using the same switch and is working fine.
