I am making a control circuit for driving back to back 2 SCRs..here is the attached pdf ..please have a look on the schematic..the operation i have understood by seeing the video
http://www.youtube.com/watch?v=&feature=player_detailpage
what is the use of resistor in it.??what if we dont put...
Hi evryone,
I am making a 3 phase KWH meter.i an using IC WT7752B.can u please tell me the procedure to calculate the exact frequency using this IC (attached in pdf format)from a power consumption of 1KWH...
i cannot make out reading this datasheet even..please guide
helo evry1,
I am making a schematic of a project gps gsm based tracking device.m very new to this field so kindly help me out..
microcontroller used is MSP430F5505.gsm module used is telit's GL865.gps module used is GNS501.
R8 nw m dealing (makin schematic of)with the gps section.so kindly tl...
thank u nishu..but 1 thing i am designing a device which will be covered overall(m designing a gps gsm based tracking device),so dont u think the use of LED is unnecessary...it wl increase the cost.
what is the meaning of term in rush??surge protection m planning is for the discrete components...the device m planning gets its power supply from 10 v adapter and so m trying to design a protection circuit firstly surge nd den reverse polarity protection.
please help me designing a protection circuit in which surge protection as wel as mosfet based reverse polarity protection is included...the maximum current that the device can handle is 2 ampere and the voltage that it can handle is 10V-40V.so accorsingly please specify the fuse specifications...
i m making a project of gps gsm based tracking device.thThe maximum current required from device can reach upto 2 A
during GSM transmit burst. The sleep curren will be less than 1mA
The device will be designed to take power from voltage range from 10v to 40V.
so please help me how to decide the...
yes 10 v power supply
- - - Updated - - -
and the protection circuit as well that includes surge protection and mosfet based reverse polarity protection??
no sir,ok i wl ask d ques again..
i have drawn the schematic of buck regulator which converts 10 v supply to 4.2 v supply...but where from this 10 V comes isn't it.so we need some adaptor or something like that from where 10 v we wl b getting..so i have to now draw 1 schematic consisting of the...
Helo,
how can we design d.c jack(along with protection circuit)for 10 V input power so that this 10 V can be applied to the pwer supply circuit for d device??please help.
