Breaking In A Power Supply (Overloading Electronics)


With a new power supply comes the tedious responsibility to ensure it’s up to the job. In this situation you could:

1. Undertake the boring, ordinary approach to load testing it…

or b) Ditch that and go straight to destructive testing.
Not to the PSU, but to anything else lying around.

The logic behind the latter option is simple. If the power supply survives where everything else is destroyed, it passes the test.
In other words, grab a bunch of components and stick them on the output.

    I made up my own bench supply, it’s a bit more compact than those 30v 5A off the shelf units, does not regulate as well thou using a pwm buck regulator off ebay but it’s good for powering and testing most things. Its a dual voltage unit 2.5v -20v 2.5v-20v and 10A continuous that’s 400Watts about 92% efficient. It can make a big mess of electronic components.

    it can take days for the smell of burning IC’s and cap smoke to subside in the workshop, had the fan going for hours, tiring to flush it out…stinks..

    WAIT A MINUTE…. Those green things aren’t resistors?! that explains why the circuits in wich I used them never worked… -_-
