boost converter box

This thing was made for combine a boost DC converter, active cooling (fan) and the power supply.

You'll need:
- Booster ZK-4KX from [AliExpress](https://aliexpress.ru/item/4000766900344.html).
- Power Supply. I used 220V-12V 5A (60W), 11 x 7.7 x 3.7 sm.
- Any fan 4010 size. I used Sunon HA40101V4-0000-c99 (12V 0.06A 3pin).
- terminal block (cables clamp). I don't know, how to describe it. The distance between neighbour contacts is about 7.8mm.

Also, as an option, buy a thermal key such as KSD9700. It can be attached to the aluminum radiator of the booster and will conduct the fan switching. I used 50C, normally open.

### Assembling notes

A terminal block on the right side is attached with brass knurled thread nuts 2 x 3 x 3.2mm and the appropriate bolts. They can be replaced with nylon ties. Also, as you can see on the photos, this clamp can be attached to another side of the box.

Fan fixed firmly in place without any additional screws. But its protector (grill) nee
