Hi All,
Just received my mailbag, so I thought just share with you. Please not it is not a full review.
Here are some internal pictures of the low cost ET5407A+ Programmable DC Electronic Load.
The kit is about 120 euro's including shipping.
Max Specs: 200W, 30A, 180V
Notable components:
- Powerfets 4 x IRFP250N Infineon hexfets
- CPU GD32F30x Cortex-M4 core, 512K flash, 64K ram
Did a few constant current tests: 1,2,3 Amps @ 20V and 10 amps @ 12V. All of these tests where within spec.
I noticed during first power the LCD would scew-up when operating the buttons, flickering additional segments randomly lighting up. Turned out that some screws where missing, after fixing this the LCD was stable..
Overall I am happy with the purchase.
