This combination of safety, performance, and adaptability positions the Samlex power supply as a highly reliable choice for powering various electronic appliances.
Had to replace a 35 yo Astron Linear PS that was making to much buzzing noise from the transformer and taking too much space. This unit is small, very silent, and I did not find any switching RFI in my radio. (TS590SG) When the fan kicks in, it’s a bitter louder than what I’d like, but it really does not happen very often. For the price, you cant ask much more.
The fan comes on in this unit after about 20 minutes and only drawing 150ma. When it does come on, it very noisy and the volume on the receiver must be turned up. While the unit does put out the correct voltage, and has not failed, the cheap noisy fan makes me wonder if the rest of the unit is also cheaply made.

Love it
I bought this power supply to power my Yaesu ft710 in my ham radio station. I’ve put countless hours in with it, and it hasn’t as so much hiccupped. For a switching power supply, you really can’t go wrong with this one. Even running digital modes like FT-8, it simply does not care.

Great Power Supply
I had previously been running a cheap power supply with my GMRS base station. Tightened up my installation and added this power supply. Good clean power for ham or GMRS radios. Will pick another one of these up soon.

This is a really good power supply.

Overpriced on amazon
Nice unit, but realized after I bought it that the price is far above what you can buy it for new from many other online retailers. Typical.

Nice and quiet
Very quiet, nice meters, and powers my 991a easily.

Odd DC Power Connections
Read the reviews on Amazon and elsewhere. Seemed like a good choice for a power supply. Spent 10 minutes fiddling with the DC power connections and decided to return for something more traditional and more user-friendly.
Howard Denton –
Highly recommend.
Arrived quickly. Performs as advertised. Rock solid.

Nice compact supply and well built.
I’ve had this since my Icom PS125 gave up on me. Since I was already using a switching supply this was an easy choice and recommended highly by a friend. Over 2 years in service and not a blip. The fan never kicked in at my old location, but recently it has on occasion, and sensitive radio mics may pick up the fan noise. Due to the slim case they obviously can’t use a bigger one that would be quieter. As for switching noise, none has been noted, and I’ve used it with rigs from HF through UHF. One minor thing is the strange posts used for the DC output, but I believe someone makes a pigtail that adapts them to the popular Anderson PowerPole connectors. Minor gripe and I’d almost forgotten about it. If I remember right Samlex did include connectors for bare wire at least.

Workhorse
I consistently run this at a 15-20 amp load. Fantastic power supply. I will strongly advise to run this device in a moderate temperature evironment as the instructions state. I found that if used at 80 degrees or above, the fan continues to run with no load and until the room cools down. Nothing wrong with device. You won’t be disappointed.

Excellent for Ham Radio use.
High quality build and very HF quiet for ham radio use.

Excellent Power Supply – No RF Hash!
Great Power Supply. I have have four of them for various radios. No RF hash at all. Stable voltage and current. Highly recommend for Amateur Radio Applications.

Very loud
The fan is very loud. I wish I had read more of the reviews before buying but for the price I guess I can live with it.
BobS –
Small is not always best. In my case the size of this power supply was perfect.
I have always been told that switching power supplies have a lot of noise in some receivers. I now have 3 of these power supplies on my HF radio, my VHF/UHF radio and a separate UHF radio. The HF radio is used exclusively on FT8 and has no problem except for atmospheric noise that I have no control on. The other 2 power supplies are used on FM radios who have some noise discrimination already. There are working very well for me.

Current meter does not get damaged when using.
Current meter does not jump around when operating a SSB ham radio.

Good power supply, low noise
I have seen several people complain about loud fan noise, but compared to the fan on my radio this is nearly silent. Under heavy duty cycle it will spin up, but I do not find it to be bothersome at all. The 12V supply has been stable and reliable for the last year, and I do not have any complaints of noise at all from receiving parties. In fact several have commented on sound quality, so no interference noted so far. It would be nice if the meters had a back light, but I have not found that a necessity. I’m glad I listened to an experienced Elmer and bought a Samlex.

Bastante silenciosa, fácil de usar
Compré la fuente para ser usada en 220V, las instrucciones y facilidad de conversión de configuración de 110V a 220V las encontré maravillosas. Arroja los 13.8V en forma precisa y con un nivel de ruido bastante bueno, solo tiene ciertos picks de ruido al encender el ventilador cuando alcanza mucha temperatura. No me ha hecho pensar en el hack para dejar el ventilador continuo.

My goto power supply for ham radio
I have three of these power supplies. I use them to power my ham radios. these power supplies are quiet, easy to use and do not introduce a lot of RF noise into my radios. the voltage is stable, all the way to 25-30 amps. If you need a 12 volt fixed voltage power supply, i recommend these.

Decent Switcher…
Have not pushed it or scanned for harmonics but it seems to be a decent supply for the $$’s, power posts stink, so a mod is in order, non lighted meters, such simple things to give it 5 stars.

Good unit
No noise found in any band, not to mention zero audible noise. Runs cool. Replaced an RS35 at 25% of the space. Even came with crimp on pins (that I didn’t use) good for 8ga stranded.

Very well made
The meters are accurate, verified both V and A with multimeter. Expensive, but I think worth the money, at least that’s my first impression.
