Default Test/Dummy Load to Share

Hi all

I decided to build a fresh selectable test load on a selfmade custom etched board (double sided)
and share it with you along with the pcb layout

I only took one photo of it but yeah.. it's not TINY!!
When working with smaller dummy loads I found it difficult to handle...
So I made it bigger... .

It uses 6x 1N5408 Diodes up to 3A capable and 5W 1ohm resistor.

It can be left open to simulate an open circuit when testing your driver (jumper removed) (do not do this if the driver is without OVP (over voltage protection)) It's ok with linears though.

You can choose from 2 to 6 diodes with a single jumper.
maybe I should have made 1 to 6.. or 7.... that later

Anyway, it has testing leads to which you can attach the DMM for voltage and for current...
read voltage across the + and the -
read current across the resistor

the input can be soldered (preferably) or attached to the voltage testing leads

anyway I post pcb layout as well. It's made in SprintLayout 5.0 very nice little software.

I post the layout in pdf format as well for those who don't have the software for anyone who wants to recreate/improve this

Default Re: Test/Dummy Load to Share

Thanks for the layout. You have some beefy components on the PCB
I have already made a 3A testload. I am sure someone will use your layout to build a testload. +1
