How good do you think this switching power supply really is
This switching power supply would not work correctly in this country it 220 volts

Re: Bakon BK950D

well you want 24v and 4-5a really.
it has no boost convertor so lower voltage = lower wattage.

there is a version with a bigger case with internal psu.

the other thing with the seperate supply base is no earth wire.
obviously you could add one.

Ive just ordered this i will let you know when it arrives and ive built it up.

Re: Bakon BK950D

can i use a genuine laptop charger as a psu for this station as i see it says from 16v to 24v at 3 amps

Re: Bakon BK950D

that's good.
the good handle is FX9501

not sure how much to trust the rating of that psu though - but the iron & controller are good.
infact i was thinking about getting one of the bare-pcb controllers to play with.

Re: Bakon BK950D

no idea, but i know it's not part of Panasonic or Rubycon - so that's all that counts.

AE brand KF series.

Is "AE" part of CapXon?

Re: Bakon BK950D

the aliexpress seller clearly states T13,
the ebay seller - with a total of 5 doesnt know what the hell he has - saying hakko936!!!

yes the aliexpress link was totally my fault for not reading the add properly, ive just sent the ebay seller a message asking for more details on that unit like does it come with the rubber handle like in the pictures and not the newer all plastic type also to confirm it takes t12 tips

Re: Bakon BK950D

i hope you ordered one with a T12 handle then - most now have a T13 handle that uses shorter cartridges!

Good spot stj ive just cancelled the order have you got a link too one that uses t12 tips and has the rubber handle thanks this is the one ive just cancelled does this ebay link look the correct one?

I know this is a old thread but ive finally just got around too ordering one of these irons and some various t12 tips.

Re: Bakon BK950D

no, it will come off clean with a wire-wool cleaner or a damp cloth

Re: Bakon BK950D

In maplins there are two solders for sale, one normal lead free solder and lead free silver solder. I want to use normal one, my tip of soldering iron used the silver solder.

Will the silver solder always remain there?

Re: Bakon BK950D

sensor is a cold junction themister - it generates voltage.

i think it's pwm.

Thanks for the info

Re: Bakon BK950D

first you need to understand the iron cartridge,
the element and sensor are in series.

so the base senses the voltage returning from the iron in between the pulses from the fet powering the element.

if you want to use a battery, you just need to use the control board and get a small 5v regulator to power the microcontroller from your input voltage.

now to your question.
if you look at the upper right of the second diagram, you will see the iron signal just before the fet branches down to an LM358 op-amp.
this then feeds the analog input on the microcontroller.

Thanks for the explanation of how this works

What type of sensor is it ?

Do you know how fast the pluses are

is this like PWM or is a set pluse that does not change in value
