Hi,
I am using SIM900A gsm module in my project, simcard is not getting registered with the network, during power on when i measure the voltage at SIM_VDD pin it shows 1.33v and suddenly drops zero,and the netlight LED glows faster, but as per the datasheet the voltage at the SIM_VDD pin should...
dear tahmid,
i am using relay to trigger the start and stop of the motor,so it is possible to suppress the back emf across the relay itself or should i use any diodes ??

hello ,
i am using a microcontroller (atmega64) to controller the induction motor but due to back emf my code in the controller gets rebooted....i have connected diodes in parallel to avoid the back emf..,but the back emf is not getting suppressed....now my doubt is to use other diodes or to...
then how could u test it..?
i have one 2/3 phase converter in which input is 415v in two wire each and the converted output should be 415v in 3 wire(3phase)...but i am not getting 415v in yellow phase(L2) instead its showing 0v and in other phases its proper i mean 415v...
can u pls guide me...
i dont know about the part number ,i need only the basic connection of 6pin relay with 12v dc input...i mean how pins are connected wrt load and control circuit.
thank you
