High Precision 4-Digit LED Display and Fine/Coarse Knobs: The dc power supply variable 30V 10A is a professional power regulator with a high resolution of 0.01V and 0.001A. Are you tired of the time consuming single knob potentiometer adjustments? This DC power supply adds fine and coarse knobs to help you quickly set the desired current and voltage values. The backlit 4-digit LED display accurately shows voltage current and power values, making it easy to view even in low light conditions
Stable Output and Auto Switch C.C/C.V Mode: The bench power supply is a low noise, low ripple continuously adjustable lab power supply that runs without worrying about producing annoying sounds. Constant voltage and constant current modes can be switched automatically, adjusting the current when the C.C indicator is on, and adjusting the voltage when the C.V is on
5V/2A USB Interface and Intelligent Cooling Fan: The dc power supply variable is equipped with a 5V/2A USB port for charging mobile phones, tablets or other devices. When the DC power supply working temperature exceeds 122℉/50℃, the cooling fan is turned on intelligently to dissipate heat effectively. Reduce the working noise and prolong the service life of the device
CE and FCC Certification, Multi-protection, Wide Application: The bench power supply has passed CE and FCC certification. 30V 10A adjustable power supply has multiple protections: over-voltage protection, over-current protection, over-heat protection, over-power protection, short-circuit protection, leakage protection. It is the perfect choice for battery charging, laboratory, school, electronic repair, electrolysis, electroplating, bulb test, aging test, DIY and so on
Packaging and After-sales: When you buy a bench power supply, you will get bench power supply*1, power cord*1, output cable cord*1, user manual*1.We will check all bench power supply and accessories before shipment to make sure the quality of the product received by each customer is good. We provide efficient after-sales service. If you have any questions about our variable power supply, please let us know without hesitation, we will reply within 24 hours

Excellent value: 120V 3A NICE-POWER
TL;DR: this seems to be a very good design at an amazing price. High voltage DC power supplies are somewhat rare and usually expensive. Hopefully these will last for years, but at this price they already far exceed expectations.Purchased two of the NICE-POWER 120V 3A model, and they are working great. Cranking out significant power (loaded to >2 amps at 120VDC each) for 30 minutes at a time, the units become slightly warm to the touch and the fans are inaudible (in a somewhat noisy lab). This efficiency isn’t a total surprise since it is a switching power supply. There have been no issues with switching EMI affecting other devices (radiated emissions not tested). The output voltage noise is barely measurable (on an Agilent DMM, not wideband) even when heavily loaded — impressive. The voltage setting (set and then not touched) is very consistent: no need for any fine tuning from day to day or cool-to-warm. The meters (voltage, current, power) aren’t perfect but they agree “close enough” with the high-accuracy Agilent meters and certainly are convenient. Like similar power supplies, downward adjustment of voltage is slow unless a load is connected to discharge the output capacitors.Possible improvements, and these are minor: (1) The “fine” voltage adjustment seems to be a percentage adjustment: it does almost nothing when coarse is set near zero, but it has a +10V range when coarse is set to 110V (still possible to tweak 0.1V increments). (2) The USB charging port 5V 2A seem unnecessary on this specialized test equipment (who needs it?), and its front panel space could be replaced by a new switch to turn off the output voltage while allowing the cool-down fans and displays continue to operate — that would allow (downward) adjustment of voltage without needing to first disconnect the load under test. (3) Documentation could be better, such as how to re-calibrate the built-in meters (assuming they will drift in future years).

It works
Iâve only used this once so far. It works. Iâm new to all this and canât say much regarding its accuracy.

Started out bad ended up excellent
Received the item and it was defective. Contacted Amazon and had another one in 3 days. It works great and is very easy to use. Hooked to my fluke meter and it is .001 off. Couldnât ask for a better power supply. Have been using it for a while now and it is one of the best I have ever had. Ordering the 120v next.

DC power supply
5 amp at higher voltage only. The lower the voltage the lower the amperage you can get out of it
Buen producto y entrega rápida a colombia lo recomiendo ð –

It is what it is. Read on.
Tops out at 29.90 volts and 10.1 Amps did not keep a load on it though only have for 1 day so far so good. Voltages on power supply are .03 lower that my meter. Thats pretty good. Adjustment knobs have a good feel not loose or flimsy.Very light weight and sensitive on dials but manageable with a light patient touch. Be sure to read instructions if you have not had a current limiting voltage power supply before. I gave this a 3 star because it is subjective to who you are and what you want for the price and needs. If you use these a lot may want a memory preset supply for the extra money. Testing jack fit really good and plenty length, good clips and general quality.

Comenzando desde el empaquetado. Viene en una caja perfectamente señalada, dentro de ella se encuentra una nota donde se nos indica la certificación del producto, asà como el manual de uso; también viene incluido su cable de alimentación y un par de cables (con una punta tipo banano y la otra punta tipo caimán) para hacer uso de la fuente.De las condiciones del equipo al momento de su llegada. La fuente llego prácticamente en perfecto estado, a excepción de un par de rayaduras en el display (son algo notables a contra luz).Del desempeño ante distintas condiciones operativas. Una vez encendida la fuente, el display muestra el voltaje en sus terminales. Al revisar la exactitud que tiene el voltÃmetro de la propia fuente contra un multÃmetro (marca Truper), observamos una desviación en el orden de los 100 mV en general; o sea, podemos decir que tiene una buena exactitud al momento de la regulación. Además, si la fuente se encuentra bajo condiciones de carga muy alta, esta enciende el abanico integrado para disipar el calor interno.En resumen, esta fuente regulable supero mis expectativas por el precio que pague. Tiene una excelente calidad y ni hablar de la calidad precio. 100% recomendable

It’s nice and sturdy, easy to adjust and the power delivery is nice and steady under load. I use it as a PSU to feed a DC LiPo smart charger and so far, very happy with it, it is rock solid. Even under load I never heard the fan spin I guess I have not pushed it hard enough but it looks good so far.
