PSV300

Rated at 13.8, but when tested it gives 13.9-14, using this to power a mobile quad band HAM radio as a base station and it is approx 2 feet away from the radio and I get no noise from this power supply. I used my HT while on a HAM net to test and with the antenna right on the power supply got no interference from it. I tried other power supplies, but this one was the best. My radio can go up to 50W and the power supply handles it like a champ. I would def recommend this power supply to others. When powered on it is silent, when I turn on my radio I hear the fan turn on, but still pretty silent, when I tested that it could handle all the power settings on my radio the fan would start to run faster as I pulled more power, but even at max it is still pretty quiet. You can hear the fan, but it is not overly noisy. When used for an hour straight the case was still cool and the radio was a little warm. I am happy with this power supply and if I need another I would get another one of these. EDIT: I rearranged my ham area and now the pyramid is behind my radio and since moving it I still get no interference, I tried max watts on my radio and it Didn’t get warm, the fan ran no louder then when using 10W so still very happy buying this, after trying a few others before I wish I just had spent the extra money and bought this one, an internal(not for outdoors) power supply had the save rate with variable voltage preset to 12.1 and even setting it to 13.8 it even couldn’t handle 5 watts.

First of all, for all you saying the fan is too loud...you have a strange version of loud. My cooling fan turned on full blast when I turned it on for the first time, and my amp went into protect mode. What did I do? Cry about it and return it? No. I turned it off and back on and it worked like a charm. :) I don't what yours is doing but my cooling fan is running at a very quiet, slow speed that you can barely hear. I am using the power supply to power a 1600 watt max amp and two Pioneer subs with 600 watts rms each. They are the 3003 with whatever identifying letters. DVC. Search "Pioneer 3003" and you'll find them. When I have the music turned up loud enough to shake things on the wall, my Kill-A-Watt meter plugged into the wall shows that the power supply is drawing about 100 watts. I must have an extremely efficient amp? This power supply works great for subs if you have an amp that doesn't suck power. I figure that I can go up to about 300 watts drawn before I start to worry about the power supply. Very very happy with the purchase. I will follow up if anything bad happens to the power supply, but it is working like a charm. I'm saddened by all the bad reviews on this. It is BY FAR the best deal on the market for power supplies. Thank you for such a great product!!!

I have purchased a few power supplies and thie PV300 is what I'll stick with, specs, price, size, weight, quality and customer service all on pont.

I have been happy with this product over the 4 years I have owned it. I have not noticed problematic acoustic or RF noise. I have used it indoors and have not had an issue with overheating when powering a 20 watt mobile radio.

Mine came with a loose screw in the case. I opened the case, and it looks like it was one of the screws that holds the board down. I tried to reinstall it, but it looks like the hole was stripped out. So I just removed it and the power supply appears to be working just fine. I use it to power a car radio with 2 speakers and a 12" subwoofer in my garage. So far, so good! I can annoy my neighbors without any issues haha. In all seriousness, I actually keep it pretty low, but it is definitely loud enough to fill the garage :) The fan is a little audible if the room is quiet, but once i turn the radio on, you can't hear it. It might be annoying if you're planning on leaving it on all the time and it's on the desk right next to you.

I put this into service in 6/2016. I am updating this review in June of 2019 to say that this has been an EXCELLENT power supply. I wired an hour meter to it from day one to track the time I spend testing equipment. We are at 2001 total hours with no issues, and many of these it was operating at 5-15 amps and above! I added a digital gauge to measure the current draw and voltage out of it just because I was curious to see what the products I test use for juice! It's quiet and puts out CLEAN power with no interference. I don't know why so many people think it's loud. I never really hear it. I suppose if I was locked in a dungeon doing HAM radio in complete silence, I might notice the fan a little more, but that's not my deal. Even when I push it, I can only barely hear the fan over background noise. 👍🏻 I own two of these and would buy another if I need it.

I was a bit skeptical about this supply due to the bad reviews. There were a lot of good reviews too so I thought I would take a chance being a cheap bast&%$. Anyway the supply arrived and the first thing I did was open up the top and check out the inside. I was impressed with the construction and very heavy DC leads inside that feed the 5 way binding posts. I powered it up and the fan is super quiet despite all the reviews. In my very quiet shack I can hear it but it is not anything to freak out over. Maybe Pyramid has been improving it over the years? I connected it to my Yaesu FT-2800 75 watt 2 meter mobile and ran it at full power with no issues. That is about a 15 amp draw according to the owners manual. I will update this review if I have any issues.

This is a rock solid power supply with a great low profile design, easy to reach terminals, and offers stable delivery of power to my radio's. This is the second PSV-300 in my ham shack and a reliable accessory on my bench.

I bought the PSV-300 30 Amp supply for my husband, he’s always used second hand Pyramid power supplies and even restored one about 8 years ago. So knowing that he’s had such good luck with the second hand Pyramid power supplies I pulled the trigger and bought him a new power supply. The shipping was quite fast, I ordered the power supply on November 26th/2020 and was due to arrive on November 30th/2020 but to my surprise it arrived the morning of November 28th/2020!! When the power supply arrived I sent my husband out to the porch to get the package and to open it, well he did and lit right up! When he took the power supply out of the Amazon shipping box he was quite shocked that it was so light in weight, he said it’s much lighter than the older PS-21KX 20 Amp power supply he restored and is currently in service. So far this new PSV-300 seems to be working flawlessly to power his 2m VHF AllStar node, he says that he is quite happy with it!! Both him and I would definitely recommend to any Amateur operator on a budget!! I give five stars!!

I needed a DC power supply to run some sensitive electronics. This unit appears to fit the need perfectly. The output voltage is exactly 13.8v, which is what it claims to output. While I did not run a 30A load on it, it seems like it would handle it, though like any supply, I would only run 80% continuously. For my purposes 30A is overkill, but nice to have more than too little. It is fan cooled, and the fan will run louder as load increases. If you find the fan loud I think it would be easy to replace with a better fan for only a couple dollars. For me it was not loud at my normal load. The overall build seems solid, and the output connectors will accommodate different types of connections like banana plugs or simple bare wire. I am happy with the purchase.

I am a ham radio operator and this power supply works great, can handle two hight power radios at a time, my 1 meter and my 10 meter. this is the second one of the power supply I have purchased

Is it supposed to take 24 days ship with in Canada/ US? Ordered: May 26 Received: June 18 You can actually purchase compact inverters in the automotive section of WalMart/ Canadian Tire. They function the same as this Pyramid PSV300 Heavy-duty 30 Amp Switching Power Supply. However, the small inverters (like in WalMart/ Canadian Tire) probably don't efficiently bridge-rectify power as nicely as the PSV300. Because, I'm into hobby electronics I've come to learn this. (Its the difference between full-wave rectification/ half-wave). The PSV300 likely has a higher amperage rating too. I don't know what other customers are using this for, but I am using this for my base station CB rig. Yes, it the PSV300 apparently works well. CB radio manufacturers refuse to offer an affordable base station radio that plugs into the 120VAC wall outlet. So, this creates complexity and cost to the customer. So, the solution is to purchase a Pyramid PSV300 to power a mobile CB radio. Oh, and if you're considering hooking up a linear amp to you base station CB, that is going to need a power supply too. (Just don't exceeds the legal power limit. wink wink) So, you might as well purchase two Pyramid PSV300s while you're at it. (I've watched videos on YouTube where a single power supply, like the PSV300, was insufficient to power both a mobile CB radio and linear amp.) Its frustrating, because good advice on setting up a base station is seemingly scarce. And, Amazon provides little in the way of affordable pre-conceived base station rigs. If one of the popular brands manufactured an affordable base station with built-in power supplies, hundreds of dollars in purchasing power supplies could be avoided. Thus, purchasing a Pyramid PSV300 would be unnecessary.

gets the job done. arrives well packed. 5 months ish update... you can beat the crap out of this power supply. I have been roasting it for 5 months. Even if it's a switching psu it is rather clean .. not much noise.. I used it to power an ham radio amplifier. I was skeptical of using a switching psu for it. I do not regret it for the different in weight and space. it is not ideal but you will never find better at this price range. good purchase. I still give it 5 stars
