	I got a DC source 130V 100A a battery charger and I got a load; Batteries that are to be charged, in between there is a DC contactor that operates on 230V AC 50HZ. My problem is when there is a power fail the contactor is taking 200 to 400 mSecs to completely open. Is there any other switch or contactor that can open the circuit within 10 mSecs or less? __________________ Subramanyam

	Dear Subramanyam Static switch can do the job, like those used in UPS, but are costly. Thanks and regards Ashok Toshniwal, Bangalore, India
