Buying Multimeters: The Uni-T UT61E
This is not a review, just a quick teardown of the Uni-T UT61E. If you expected a review, check out the in-depth review by Martin Lorton on youtube:
- Part 1: First Look and Basic Functions
- Part 2: Look at PC data logging software, UltraDMM software, mains measurement and more
- Part 3: A look inside at input protection / build quality.Test battery consumption and low warning
- Part 4: Torture test to see temperature stability and calibration with DMMCheck
And to balance things out, also check out what Dave Jones of the EEVBlog has to say about the Uni-T UT71E and UT61E in general.
DPS-800GB A 1kW 12V 82A HP Server Power Supply
I recently snatched Four of these nifty 1kW power supplies. They were all used but still working. Well I kinda damaged one of them but more on that later. Here are a few shots of these things. They’re pretty compact for that amount of power.
Here they are removed from their cases and ready some customization. To disassemble, remove all screws on the outside of the case except for the Eight that hold the fans in, remove the lid, remove the Four screws in the corners of the PCB. Pop out the mains connector and push in the LED. Then you need to pull the mains plug out of the case so you can guide the mains wires through the opening where the mains plug was. It’s a bit fiddly but It’ll come out. Just be patient and try not to rip off the caps and whatever else is soldered to the mains plug. The fans are in their own little subassembly which can be gentrly pried away from the rest of the board after unplugging the fans. Please not that the PSU will shutdown a few seconds after powerup when either of the fans isn’t connected and running.
Always check those cheap electronics parts for faults
Yes tons of stuff can be ordered for next to nothing from China but be sure to check the quality. So sometimes this stuff is just billig (cheap) and not günstig/preiswert (good value for money)…. Caveat Emptor.
