Inside a metal power filter

Having recently taken apart a stylish audiophile power filter, I thought it would be interesting to buy a traditional metal cased unit and look inside it.

Most of these "pro" filters have a label on them showing the components used inside.

The construction is quite neat and in a way very "retro", with strong vibes of the metal cased filters used in older radio equipment.

You'll find cased filters like this on the incoming supply of many motorised appliances like washing machines. The arcade game collectors will probably also recognise this style of filter on the incoming supply of some video games and pinball machines.

The bare circuitry on its own is often used in good quality switchmode power supplies.

This one came from AliExpress (not a sponsor), but they are available from most electronic distributors.

The model number is CW1B, with a few different versions depending upon the expected load current.
