I like to look at these when riding on the back of my husband'd motorcycle since books flap around too much and I can hold these with one hand. The first time I looked I could hardly understand them, but as I learn more about electronics I'm delighted to find that I understand more and more.
I like to try to take two random cards and then build a project that uses them both. It's fun and I learn a ton. Of course I do the soldering at home, not on the back of the motorcycle.
I bought this item as I had some systems to stress test. This involved loading both the online and offline power supplies to the rated limits for 24 hours. This test was followed by overload testing to see just how far we could push the system.
We built the Re:load2 into a metal box with an inline digital ammeter. We also have output to a logging system. The heaksink was coupled to the box side to improve thermal coupling although we were not overloading the unit - just good practice we think.
The block is of excellent quality. All holes did need to be punched once each to get rid of excess drilling spills. The holes themselves are precision-drilled. It might be worth mentioning that it is pure aluminium, not anodised. The accompanying pegs are not all of equal length though, which is not a problem functionwise, but easthetically speaking imperfect.
Overall working great.... come to notice that the MOSFET is not BTS141 as stated in the website. the one i got is BTS133. is there any reason behind this change? bts141 seem to have a better power rating compare to bts133
