TP30SWV 30 Amp DC 13.8V Digital Switching Power Supply with Noise Offset

I've been using this 24/7 for several months to power my HAM and CB radios. It has never faltered or lost it's set voltage of 13.8 even when drawing 10+ amps. Feels solid, looks good, heavy. I have this setting next to my radios and it has never induced noise that I can detect or a listener can detect. Great power supply. I will probably buy another one when I expand. I like that the voltage is adjustable or your can use the default set adjustment of 13.8. The digital display is easy to read and displays amps as well as voltage. Love this thing.

I was searching for a first power supply for my UHF/VHF mobile, this has the cigarette lighter port that allowed me to get the radio powered and on the air. The panel displaying the voltage (I used the selector for 13.8V fixed) and the amps simultaneously lets me see what my radio is drawing on each band and power setting. The binding posts on the back will be utilized with a ring to powerpole cable and dc distribution panel and new cable to radio setup. This will allow the power supply to supply all my device connections for current and future use. The cigarette lighter port will get a USB charger adapter to connect my 12dc laptop and charge my HT radios.Overall a great first power supply to get you going.

I bought this to power a sub/amp setup that I had taken out of my old car when I got rid of it. I was unsure if it would have enough juice. Two 300 watt rms alpine R-12s paired to a 600 watt rms alpine amp. Everywhere you read, people will tell you that the math does not work since this thing is only rated at 30 amps but I'm happy to say that it works like a charm. The subs slam hard enough to vibrate all of my doors in the basement and pictures on the wall in the rest of the house. And going by the digital readout on the front, the power normally stays in the 5-10 amp output range during bass heavy movie scenes and lower when listening to music at normal levels. So it clearly has the headroom to power an even more powerful setup if that's what you have. I highly recommend this to anyone looking to do a reliable, clean and SAFE conversion.

it runs my Stryker 955 just fine. the Stryker wants all the voltage it can get.

This appears to be a well built power supply. Using with a Yaesu FT-710. My first impression was that it was heavy enough to put out the amperage as advertised. You expect a 30 amp supply to have some weight to it. Some complain that it doesn't have USB ports. You can always get one of the 12 volt car adapters with up to 4 USB ports. The one pictured even shows the voltage out at the connector. It only has 2 ports but you can also get them with up to 4 ports as shown in the second photo. Happy with my purchase.

The TP30SWV was easy to set up and start using. It generates very little heat and is simple to use. I really like the switch on the back for 13.8v. This is how I would primarily be using it. There is also the option to have an adjustable power choice. It appears very easy to use and simply to adjust. It is silent in running other than the fan when it turns on which isn't often. It appears to be made with good quality, and is definitely a great value for the money.I would highly recommend this product.

The media could not be loaded. Another customer accurately described this power supply as good but "produces gobs and gobs of radio interference, so if you want to use it to power a receiver or a transceiver, prepare to be disappointed." He went on to say that "there was a knob in front that lets you shift the switching frequency of the PSU, but this doesn't really fix much, unless you want to be spinning that knob all the time."That said, I found a solution and wanted to share it here. Per common practice for some HAMs, I wound the output power cable through a Ferrite Ring, and it completely eliminated ALL of the noise and harmonics on every band. I included a before and after video for reference. I hope this helps someone...

I've owned mine since 2021 and I run two amateur radios with it. It's very quiet and reliable. I intend on purchasing another one to run another HF radio. Highly recommend it.
