Important Usage and Safety Instructions
Please follow these guidelines carefully to ensure reliable and long-term performance of your 12V power supply.
1. Ventilation and Operating Conditions:Operate the unit in a dry, well-ventilated environment. Avoid sealed spaces or placing objects on top that could block airflow. Continuous heat buildup can reduce efficiency and shorten lifespan.
2. Voltage Configuration:The power supply is factory-set to 110V/115V for U.S. regions. If operating on 220V AC, move the selector switch to the correct position before powering on. Always verify input voltage to prevent internal component failure.
3. Load Management:For optimal efficiency, operate the device between 70–80% of its rated current. Overloading or prolonged use at full capacity may cause overheating or premature aging of internal parts.
4. Wiring and Grounding:Confirm that all terminals are securely connected and polarity is correct before applying power. Use appropriate cable thickness for your load. Proper grounding is required for electrical safety and noise suppression.
5. Maintenance and Inspection:Inspect the unit periodically. Clean vents with compressed air or a soft brush depending on the dust level in your environment—typically every 2–3 months. Check terminals for looseness or corrosion to maintain stable contact.
6. Environmental Cautions:Use indoors only, away from moisture, condensation, or high humidity areas. Do not install near water sources or in corrosive environments. In areas with unstable mains power, consider using a UPS or voltage stabilizer.
7. Radio Frequency Considerations:This unit includes an EMI/RFI filter to minimize interference. However, it is not intended for direct use with sensitive radio transmitters or amateur radio equipment where noise isolation is critical.
8. Safety Warnings:High voltage exists inside the housing—do not remove the cover or attempt to repair internally. If unusual sounds, heat, or odor occur, disconnect power immediately. Installation should be performed by a qualified electrician. The package does not include cables, switches, or screws; please prepare them as needed.

Very good and stable power supply
Purchased as part of a TIG Cooler build to run the pump and fans. Specifically selected because it has way more power output than needed so we’re not overtaxing it and because it is switchable between 110 and 220. It is setup to run off of the welders dedicated 220 output plug for a cooler and works great.The pump and fans never sound like they are taxed due to low power input. The power supply runs cool and is SO QUITE. When checked with a multi meter voltage and current outputs are stable and consistent.I expect a long life out of the unit and it was a great price in my opinion for what I got.

Perfect for any lighting projects.
Works Great! No major heat issues. For the price I would recommend this to anyone working with lighting or tech. Very durable and steady power output.
Amazon Customer –
I got it overnight
No on off switch, used it at Field Day worked with no problem. Voltage did NOT vary a 10 th of a volt while transmitting100 watts of power. Price is very reasonable for a quality product.

works fine
No instructions manual. No power cord for the 110 volt AC side. Good thing I know a little bit about electrical.

Excellent poewer supply for low voltage landscape lights
I overloaded my 20 year old power supply for my low voltage landscape lights and was surprised to find that its hard to find a 12v dc low voltage landscape power supply that would support 80-100 output watts. Apparently the advertised 120 watt systems are actually 2 60 watt supplies which wouldn’t work for me. I found this system which works great! My power supply is in the basement so weather is no problem. I’m running 80 watts plus wiring and could easily add a second 60 watt system I have if/when it should fail. The power supples for low voltage ladscape systems are very expensive (timers, water proof, etc.) If its not in the weather, this is the way to go. For a timer, I use a mechanical timer on my ac feed.**** Followup – the power supply failed after 4 months. I contacted the seller and received a new replacement in a couple of days – very good warranty coverage!

Poor voltage regulation, seemingly poor build quality
I rarely return things to Amazon but this one is going back. It arrived with no documentation–it was just the power supply in a box marked “made in China.” The unit had no labeling for specifications or connections other than some weakly stamped symbols near the unmarked terminal strip. So out of the box it was not very impressive.I connected a 60 watt test load (an incandescent bulb) to the 20A unit and it seemed to work ok. But with a meter and scope I could see that the voltage varied from about 8 to a bit over 12. The changes were usually abrupt, but sometimes the voltage would drift between 10 and 12 over a 5 second period. My application requires a regulated voltage, so I can’t use this power supply. I didn’t test it at a higher load.I was also disappointed with the build quality. The case/frame is very lightweight aluminum that flexes easily. I see some thin insulation under the circuit board to hopefully prevent the solder contacts from touching the case. The small mounting flanges built into the frame are very flimsy, as if they would break off easily. This is not a robust device.There is also no UL listing even though the search I did on Amazon included UL Listed. The description on Amazon doesn’t mention UL, so I can’t say it was inaccurate. But a device like this that will be used in an unattended and potentially enclosed space should be UL listed, or have some other equivalent certification.There is nothing to recommend about this power supply other than its low cost. Buyer beware.

Using for ham radio power supply
Basic switching power supply. OK for 2M/70cm, but too noisy for HF use. Using for a couple of radios in our city comms center.

Me llego en tiempo y forma, lo estoy utilizando para la alimentacion de un amplificador de 400 watts y un restaurador de bajo que se conctaron en paralelo a la fuente y no ha dado ningun problema, ha funcionado a la perfecccion, la conexion que realice la he utilizado por horas y la fuente ni siquiera se calienta (la cual trae abanico integrado).En conclusion es un excelente producto a un buen precio.Como consejo revisen el consumo de los aparatos en amperaje y voltaje antes de seleccionar una fuente, de poder, de eso depende el funcionamiento correcto de la fuente.

the product i got fried itself as soon as it was plugged in and I got a certified electrician to hok it up
Comprador X –
Funciona muy bien me da los watts que indican al precio que esta no le pide a otras fuentes de marca lo recomiendo aparte el ventilador muy apenas se alcanza a percibir
GABRIEL HERNANDEZ –
La fuente funciona a la perfección, la instalación fué sencilla ya que vienen marcados los positivos y négativos, asà cómo las coexiones de la corriente alterna.

Have to wire it yourself- so be prepared for some DIY- does not put out 12 volts- eleven only, but works for my use- needs a separate voltage gauge- be nice `
