DC power supply (0-30V,0-10A) adjustable, switching power supplies, mini high precision 4-digit display with USB fast charging interface, variable lab bench power supply, output button/encoder knob

Wasn't quite sure what to expect for the price, but I am happy to say I'm impressed! This power supply feels solid and well made and measuring the output with a decent multi meter shows it's also very accurate as well! The USB outputs are super handy and support properly negotiated fast charge too. This thing isn't exactly going to win any desktop PSU of the year awards, but from my brief experience with it I genuinely cannot find a fault with the exception that perhaps the button functions being a bit difficult to make out (just adding a touch of white paint to the engraved labels would have been perfect). But, there's only four buttons and once you know where they are it's a non issue. Quick tip, long press the adjustment knob to turn off the thoroughly annoying beep.

A very well engineered product. Nice robust controls and bright display, runs nice and cool. Recommended

Good, clear display, easy to use. Above 5W power draw fan comes on every few mins for a few seconds and it is not a quiet fan... a major annoyance for me. Measured ~80mV pk-pk noise @ 24V 300mA where I'm using it. Beep on button press can be turned off if you read the manual...

I needed something better than my ancient desktop PSU so thought I'd give this a go. So far so good, checking output against setpoint is less than 20mV difference. It's got a nice way to set the output using a combination of pressing the knob to select the digit and turning it to set the value. As others have said there's a very annoying beep by default every time you touch or turn anything, but instructions in the rear of the manual show how to turn this "feature" off very easily. Fast charging USB port is a nice touch. I checked the current limiting function by stalling a DC motor and it works perfectly. It's a really good looking PSU and very compact, the fan doesn't come on unless drawing lots of power, so most the time it's silent. I love the white display, nice and modern. It's early days, but if it's reliable then a great buy.

I have had this power supply for almost two years now, and it has been one of my best investments in equipment. When I first unpacked it, I was surprised how lightweight it was. One expects a power supply to be heavier - for all the radiators and transformers inside, so I thought at first that this power supply could be cheaply made and saving on components. These two years have proved that I was wrong. It was my primary solution for all my elctronics DIY projects and has not failed me once. The output voltage is quite precise and its current-limiting capabilities have saved my devices a few times. I would definitely recommend it as a desk power supply to any electronics hobbyist.

Fantastic DC Power Supply – Compact, Precise, and Feature-Packed! I recently purchased this adjustable DC power supply, and it’s quickly become one of the most valuable tools on my workbench. Whether I’m working on electronics projects or need a reliable power source for testing, this little unit delivers on all fronts. Accuracy and Performance: The 4-digit display is one of the standout features of this power supply. It provides precise voltage and current readings, making it ideal for projects that require fine-tuned adjustments. I tested its accuracy with a multimeter, and the readings were spot-on, even at lower voltage and current levels. The 0-30V and 0-5A range is perfect for a variety of applications, from powering small components to more demanding devices. Build Quality: Despite its compact size, this power supply feels solid and well-constructed. The metal casing gives it a premium feel, and the design is sleek and modern. It’s lightweight yet sturdy, making it portable enough to move between workspaces without compromising durability. Ease of Use: The encoder knob is a game-changer. Adjusting voltage and current is smooth and precise, with no lag or jitter. The ability to toggle the output on and off is a great safety feature, especially when working on sensitive electronics. The intuitive layout of the controls and display makes it easy to use, even for beginners. USB Fast Charging: The inclusion of a USB fast-charging interface is a fantastic bonus. It’s a thoughtful addition that allows me to charge my phone or power USB devices without needing a separate charger. This feature alone makes it more versatile than other power supplies I’ve used in the past. Features I Appreciate: High Precision: The 4-digit display ensures you get detailed readings, which is essential for precision work. Output On/Off: Being able to control when the power is delivered adds an extra layer of safety. Compact Design: It doesn’t take up much space but still delivers the performance of larger units. Quiet Operation: It runs quietly, even under load, which is a big plus when working for extended periods. Pros: Highly accurate voltage and current adjustment Compact and lightweight design USB fast-charging port for added convenience Intuitive encoder knob for precise control Reliable and quiet operation Great value for the price Cons: The backlight on the display is quite bright, which might be a bit distracting in low-light environments (a dimming option would be a nice addition). The fan can kick in at higher loads, but it’s not overly noisy. Supplied Cables are not brilliant. I'll swap them out for multistrand, silicone wires. Conclusion: This DC power supply has been a fantastic purchase. It’s precise, versatile, and packed with features that make it ideal for hobbyists and professionals alike. The compact size and USB charging port are icing on the cake. If you’re looking for a reliable and accurate power supply for your lab bench or electronics projects, I can’t recommend this one highly enough!

Was initially pleased with the unit which has been used on around 3 occasions but has now unfortunately failed just over 3 months from purchasing. No apparent option to return for a repair or replacement and now out of pocket to the tune of £50 as outside of 30 day return window. Cannot recommend this item due to premature failure after comparatively very light usage.

Very nice item, you can try everyting and build before or get around 12 car electricals with out geting out or to your car battery!

Buena fuente de alimentación que cumple con lo prometido. Muy contento

The power supply has an excellent adjustability because it has a rotary encoder, combined with choice of setting which decimal you want to change, although i usually leave it at setting on the tenths. It's also very intuitive and looks nice.

Necesitaba una fuente de alimentación regulable de laboratorio y tras muchas búsquedas y comparativas me he decidido por finalmente ésta. Además tuve la fortuna de conseguirla con un descuento del 20% lo que se traduce en una relación calidad precio inmejorable. Estoy muy satisfecho con su desempeño. Se trata de una fuente de alimentación regulada de tensión continua ajustable y configurable. Puede trabajar en modo tensión constante o corriente constante en función de los requerimientos de la carga de forma automática. Su excelente pantalla de visualización muestra al unísono la tensión, corriente y potencia de salida generadas. Viene con una imprescindibles pinzas de cocodrilo ajustables a los pomos de salida con sus terminales. Como extra que se agradece y es muy útil dispone de un puerto USB de carga rápida de hasta 18W reconociendo todos los protocolos. Hay varios aspectos a destacar que pueden pasar por alto a algunos usuarios. La fuente es configurable. Basta apretar cinco segundos el botón de salida para acceder hasta seis apartados secuenciales de configuración tal como se detalla en en manual de instrucciones. Con el botón de regulación de voltaje vamos presionando y saltando de la lista de configuración y una de las cosas que he hecho es en el apartado 4 dedicado al timbre, eliminar el pitido que trae por defecto en mi caso al girar las botoneras. Cosa que a mí me parecía bastante molesta. Basta con girar el mando de tensión y seleccionar 0 es decir no hay pitido, y una vez llegado al final de la lista de configuración seleccionar pulsando de nuevo el botón de tensión para que se guarden los cambios. También puedes ajustar el brillo de la pantalla entre alto o bajo. Todo está explicado en las instrucciones. Otro punto crucial para el manejo correcto de esta fuente es el citado manual de instrucciones que solo viene por defecto en inglés impreso en la caja pero se puede conseguir sin problema alguno en perfecto castellano. Solo hay que fijarse bien y cuando hayas comprado la fuente al entrar en la ficha de producto junto a donde dice Escribir una opinión aparece un apartado de soporte de producto. Tan fácil como clicar y allí tenéis para descargar el manual de la fuente en español correctamente redactado. Nada de traducciones automáticas. Tal y como demuestro en las fotografías. Las medidas son preciosas medidas como se observa con un multímetro. Un apartado que me tranquiliza es la seguridad de la fuente de alimentación. Dispone de múltiples protecciones con sobretensiones y sobre todo contra cortocircuitos con la función programable OCP. Presionando 3 segundos el botón de regulación de corriente e iluminandose en la pantalla. La fuente es práctica, pequeña y ligera. Y comparada con otras tiene unos acabados y funciones de calidad. En definitiva si buscas una buena fuente de alimentación regulable para tus proyectos de electrónica esta es sin duda una buena opción con una excelente relación calidad precio.

J'avais déjà une alimentation de laboratoire depuis de nombreuses années, elle marche très bien mais trop lourde, aussi celle ci change tout, très légère plus puissante, programmable pour protéger mes montages électroniques

Good product, i have returned it and re ordered higher Voltage 👍
