Another power supply from OVEN: 24 V again, with an extended temperature range again, but unlike the previous one, it has lower power and is much smaller. So, let's continue our discussion of panel-mounted equipment from domestic manufacturers.

I’d wanted to buy a signal generator for a long time, but kept putting it off. Maybe because I already had a couple of basic models at home, or maybe because I didn’t really need one that badly. But after watching one of the videos, I finally decided to get one. I found the lowest-priced option available at the time, placed the order, received it, and did a few tests. I also upgraded the firmware to the higher-end model’s version.

It’s been just under a year since RuiDeng announced the previous version of its hybrid power supply, and now the developers have finally released a new model I’ve been waiting for: the same kind of hybrid converter, but with an output current of up to 12 A. Today’s “not a review” will include a brief announcement, a description, the differences, real photos of the device, and, I hope, a discussion of the new model in the comments.

I’ve already reviewed plenty of power supplies and devices made both in China and here at home. But today I’ll be testing a power supply from Owen, a well-known company that develops and manufactures industrial automation equipment. Let’s take a look, open it up, test it, heat it up, and draw some conclusions.
