variation de tension (-0.2V) lors de la mise en charge (2A dans mon cas)
Je n'ai pas d'oscilloscope mais la tension n'as pas l'air "propre" (pas bien lissé)
alimentation grillé avec l'ajout de 3 condo de 1000µF ?!
qualité médiocre qui va avec le prix. Read more
Very solid build and compact design for a switching power supply. A pot allows easy fine-tuning of the voltage. The regulation isn't all that great under a very variable load, so it's necessary to be careful or to add extra regulation stages when trying to use it with sensitive electronics. Voltage variations ... Read more
Small compact power supply which delivers a rock solid, stable, 5V. There is a pot to fine-adjust the output voltage. The case has enough perforated holes to get it ventilated. The power transistors are mounted to solid aluminium heatsink which is part of the housing.
Good powersupply once you have checked ... Read more
Power supply well built, sturdy and really delivers the marked current in the case. When loads 3,5 amperes the voltage don't drop down. The oputput voltage are regulated with a variable resistor, is useful but not necesary. None, maybe the case need more holes for fix the case to a hard place. Well ventilated ... Read more
The terminals are easily identifiable with large labels. Once set, this power supplies holds a steady voltage. The adjustment is fine enough for 0.05V adjustments, but that's overkill. The case is well-ventilated on two sides. The other three sides, the solid aluminum plates, serve as the IC heatsink.... Read more
