Wasn't sure about this as it was one of the cheaper ones, however it has performed perfectly since I had it. The outputs are accurate and easy to tune.

RUZIZAO DC Bench Power Supply
Does its Job
Would give it a 4.5/5 but as that's not an option 5 will do!🤣 It's only couple downfalls is there seems to be a voltage drift of about 0.05V when it's on, you can adjust it wherever you want but if you leave it alone eventually it'll drift -/+0.05V practically that's not much of an issue and it's a very easy fix, it's just a slightly annoying thing for an OCD person who wants it to always be the exact same voltage and not have to keep tinkering with it to set the voltage back as should be! Only other issue is just more of a personal design issue, with the switch being at the back as opposed to the front. I use to have a different power supply but I needed the extra Amperage this offers, and that had the switch at the front, which made turning it off and on a lot more convenient than this is with the back. Otherwise it's a brilliant piece of equipment that does exactly as it should- overall happy!

Excelentes características por el precio
Lecturas de voltaje muy precisas en comparación con mi multímetro de trabajo, con una desviación máxima de 5 mV desde 1,5 V hasta la salida máxima de 31 V.Jose MesquitaExcelentes características por el precio
Reviewed in Spain on 27 April 2023
Con respecto a la regulación de voltaje, la caída de voltaje máxima fue de solo 5 mV entre sin carga y con una carga de alrededor de 4 amperios. Este es un resultado excelente.
La estabilidad fue muy buena para esta prueba inicial. Hice funcionar la fuente de alimentación con una carga de una lámpara D5S LED 12V 40W durante aproximadamente 30 minutos y no pude ver ninguna fluctuación de la fuente de alimentación.
El modo de operación de corriente constante funciona como se anuncia. Medí 10,12 amperios cuando configuré el voltaje en alrededor de 2 V y acorté los cables de salida de la fuente de alimentación.
El ruido del ventilador es bajo, incluso después de 30 minutos con una carga de 4 amperios.
La fuente de alimentación parece tener una alta eficiencia, ya que no generó demasiado calor porque la carcasa ni siquiera se calentó.
Los mandos giratorios son suaves cuando se accionan. Solo el tiempo dirá qué tan suaves seguirán siendo.
La pantalla de dígitos rojos es un clásico y es fácil de leer.
El cable de alimentación es desmontable y de tipo profesional. Sin embargo, el interruptor de encendido en la parte posterior podría ser de mejor calidad en mi opinión, a pesar de que funciona bien y hace su trabajo.
Los cables de CC incluidos son lo suficientemente buenos para el trabajo, a pesar de que se detectó una brecha menor al insertar los conectores tipo banana en los terminales de salida de CC de la fuente de alimentación. Dado que estos conectores tipo banana son de tipo resorte, su fuerza se puede aumentar ajustándolos.
Con un peso aproximado de 1,5 kg, esta fuente de alimentación parece ser lo suficientemente resistente. Todos los paneles de la caja están hechos de metal, solo las perillas y los terminales usan plástico.
