Hi Guys,
Please help..!
I have attached the circuit. I have difficulty on how to set microcontroller P3.3 and P3.4 into high and low state:
There are only 2 condition:
(1) If I short SO pin 1 and 2 .. I need low (0V) at P3.3 while the P3.4 is high (5V or 3.3V)
(1) If I short SO pin 3 and...
Re: soldering procedures
Hi Lakshmi,
Soldering process usually use solder paste, it will print initially to your pcb using stencil to match the paste to your PCB land pattern, then components will be mounted using auto-machine. It will subject into reflow process (oven ranging 333deg and...
breaker test
Hi Every one,
can somebody help me to test curent trip limit for a circuit breaker LEGBX66-33643-1-V in particular.
Is it possible to test this using dc source with 12v input and putting 30-40 ampere on the loop using (resistor load)
we observed that the tripping time takes...
Re: reverse voltage test
Hi brian,
Thanks for the help.
thats a great option, but it requires another supply for relay bias right.
Can a combinational transistor can do this. i just dont have any idea on the configuration.
thanks
Hi All,
can you help me please to provide schematic for this. I Need to test reverse input for dc power supply.But I need to make sure the power supply doesnt have charge before I inject reverse voltage.please help to provide schematic,, need to discharge first the pre-voltage on the bulk...
Hi actually your correct, You just need to know the maximum and minimum load current. If you put the maximum and thats is heavy load and minumum is the otherwise.
Hi people,
can somebody help me. how to program at ATMEL, and what ATMEL IC to use to control to output port equipment tends to measure resistance (interconnect) at many points.
Thanks
appreciate your response
Hi all,
can anybody help to provide complete block diagram of SMPS?
Appreciate if you include importance of each and how it affects/relationof the other circuits.
Thanks!
