Identifying the Triplets in a Power Supply Front End

A great overview. I have one remark about one of the last sentences: a capacitor has infinite resistance.

Before the inrush surge limiter came into the market they used a circuit that would shunt out a series resistor after awhile.

Nice post John.

I like your approach to looking at legacy systems and identifying components and where you find them.

It has been a long time since I looked at the in side of a power supply. I have just used the components available as a block.

Well done.

I like how you take this subject and boil it down to simple pieces. Great style to.

Thanks,

Great post and a very good resource for anyone working with the input side of a supply.

MOV's could also be fitted between Phase and Earth and Neutral and Earth.

I've used 24v versions on the Skifield to ensure those nasty induced voltages from lightning don't overwhelm the input of the trip system.

The Keysight IR tester did a great job of identifying faulty MOV's used as Line Protection devices.
