SK150c Adjustable Power Supply Mini Enclosure2

Due to the needs of electronic DIY, I recently looked at the adjustable power supply finished products on the market. Mature industry top brands like Ruedeng, Ke Ruiyuan, and Uni-Trend are priced at around 300-500. Of course, I've also seen SK120 series products for less than 100, but the community feedback indicates overshoot issues when connecting loads, poor accuracy, and unacceptable ripple. Recently, a new product, the SK150c, was released, reportedly addressing these issues. So I bought one to try out. Due to slight specification changes, I redesigned the enclosure. It's simple, featuring only a 5.5-2.1 DC input (φ8mm), two M5*45 banana jack outputs (φ6mm with a 2mm positioning hole). Additionally, a small window is provided on the side for TTL connection to a host computer.
