48 V, 125 W power supply: inexpensive but surprisingly good

While working on a project to build a device for testing and balancing large battery packs, I needed a power supply of around 90 V, so I bought two 48 V, 2.5 A power supplies. They turned out to be unexpectedly decent despite their low price, both in terms of performance and build quality. As usual: inspection, schematic, tests, conclusions.
Voltage converters: compact, powerful, and galvanically isolated

Today’s review is about some uncommon, specialized devices that can nevertheless be very useful: powerful, compact voltage converters. What makes them unusual is their 36–75 V input voltage range, which is rarely used by DIYers. But I’ve been asked about converters like these several times, so I decided to fill that gap, since I haven’t come across any reviews of them.
