Health and Safety

Dismantling a power supply doesn’t include any harmful steps. Nonetheless workers should wear personal protection equipment like gloves, goggles, apron and robust shoes.

What you need

Step 1 Power Supply Disassembly

Power Supply Disassembly, Power Supply Disassembly: step 1, image 1 of 1

Remove the steel casing, clean it and put it aside.

Step 2

Power Supply Disassembly: step 2, image 3 of 3

Remove all components like cooling fan, PWB, transformers, copper windings by cutting off cables and wires and place them aside.

Step 3

The PWB contains relatively large aluminium boards acting as heat sinks. Remove them and place them aside.
Take care that aluminium is properly cleaned. Aluminium recyclers refuse impure parts.

Step 4

Separate the remaining materials according to their type and go on with the appropriate data sheet (e.g. aluminium, ferrous metals, cables, plastic, further PWBs, capacitors etc.).
