SK120 dual power supply

알리익스프레스에서 여러 베스트셀러 상품이 있지만 SK120으로 대표되는 벅 컨버터가 아주 유명하다. 이 파워서플라이의 최대 단점이라 한다면 케이스 없이 본체로만 판매가 된다는 점이다. 아마도 처음부터 DIY를 위해 출시한 것 아닌가 하는 생각이 들 정도이다.

이번에는 이 SK120 2개를 사용해서 듀얼 파워서플라이를 제작해 보았다.

전면부에 바나나잭 단자대를 사용하지 않고 XT90H 단자대를 사용해서 배터리 충전 등에 유용하게 사용하도록 하였다.

전면부, 후면부, 메인프레임, 덮개 이렇게 4 파트로 디자인 되어 있으므로 유저가 원하는 부분만 변경하거나 업그레이드 작업을 진행하기 매우 용이할 것이다.

각 파트를 메인프레임에 고정하기 위한 나사는 M3 5mm면 충분하다.

필라멘트는 PLA BASIC WHITE로 본체에 적용하고 TEXT는 PLA BASIC ORANGE를 적용하면 충분하다. 기타 프린터 설정 값은 모두 기본 값을 사용하나 서포트를 활성화 시켜서 출력하길 권고한다.
