Ham Radio Power Supply - The Right Choice

There are a wide range of power supplies suitable for Ham Radio Transceivers. But it's important to make the right choice, particularly as it is an item that should be "fit and forget!"

always great information. Thank you!

Our pleasure!

Very well description.

[@robertallbright]

Thankyou Peter I have been thinking of buying the Nevada PS1335 especially after a recent mains failure where we were without mains for several hours. I connected up my big 12V leisure battery to run my Yaesu FT-710 So the PS 1335 could be very useful 😊 Useful to hear your comments about the quietness of modern switch mode units, I find various ones I’ve tried quiet also.

[@watersstanton]

Thanks Robert. Good to hear from you. 73 Peter

I bought one of the Nevada linear power supplies from you when the 40 amp one was on special offer. The fan is a bit noisy, but I put it on sound isolating blocks which made it more manageable. I also invested in the MFJ power pole distribution board. This really tidied things up. When I set it up I realized I will probably never need to buy another PSU. Makes me feel old .

[@watersstanton]

Forget getting old, just keep enjoying Ham Radio. Last week I worked a 93 year old G station. 73 Peter

@@watersstanton I have a long way to go. 55, but licensed for 41 years.

I'm rather partial to open frame switching supplies meant really for integration into commercial and industrial equipment. These are no nonsense, just works, inexpensive and efficient bricks for high quality DC power. Mean Well is a reputable manufacturer. Pick one up the next time you've a shopping cart with Mouser, Arrow, Digikey.

My concern is long-term reliability. More "advanced" (more Chinese components) has usually equaled less reliability.

[@watersstanton]

Try buying British, but I fear the "internals" will come from the geographic area you are trying to avoid. 73 Peter

Another good video, as always, Peter but I feel that both of those power supplies might be a bit of 'overkill' for someone who simply wants a decent power supply that works well (without the need to charge a back-up battery or to vary the output voltage). The Nevada PSW-30H, that I use myself, would possibly suit many people's needs perfecly well and is £30 cheaper than the PS-1335. (I bought mine from Waters & Stanton, so I'm not promoting any rival company here!)

[@watersstanton]

Yes you are correct, the simple fixed voltage with no frills is ideal for many ops. 73 Peter.

[@redstickham6394]

Another great video. I have a Jetstream JPS28 switching power supply and it works pretty well and as far as I can tell, it doesn't generate noise. It is also lighter than the Astron non -switching supply that it replaced. That Nevada supply with the battery charger is pretty clever. Are those available in the U.S.?

[@watersstanton]

Not under the Nevada brand name, but maybe available in USA under another name.

[@One-Eyed-Willly]

Pretty neat psu. I run a psu with a powergate, connected to a Biolenno LiFePo4 battery. What battery types does that support for whitch you own?

[@stevetelford2821]

Hi Peter, once again a really nice video. Must admit I like the sound of the Neverda with the trickle charger to charge my battery I use for portable use, but I have a question, does it trickle charge a sealed lead acid battery? Realising they like a constant voltage, and does it continue to change when the mains switch is off? Cheers

[@watersstanton]

Many thanks Steve.

HP ex-Server Power Supplies (e.g. DL380 HSTNS-PD18 or similar) are fairly common on the usual online marketplaces, sometimes aimed at crypto miners. As-delivered they provide ~12.5 volts, but that can be modified with one added resistor up to ~13.5 volts. This sort will typically accept any AC voltage and frequency (100-240vac, 50/60Hz). They do have a small fan, but it's regulated and usually slow and silent. They're designed to be top quality, seem to be no RF noise (haven't noticed any), and they have some good protective features (e.g. OVP, thus reportedly can't quite reach 13.8v reliably, without more complicated mods). There are quite a variety, so make sure you match the PN to the available mod instructions. Here are the two punchlines: 1) Rated at 62 amp output (maybe don't push it), and 2) around typically Cdn$20 or $25, + shipping (YMMV). I've never seen any other option that's even close to the price/performance ratio. I've got one (and three spares) for less than one-third the price of a commercial product that's not even as good. Runs my rig (purportedly up to 23A) easy peasy. Do your own homework of course.

[@watersstanton]

Many thanks.

[@alzag6hpr553]

Hi Peter, excellent video once again. Can the Nevada power supply be taken for portable use since it has battery backup facilities for mains failure, think this would be good for a steady 13.8 supply rather than running straight of the battery from the radio. Thanks Peter.

[@watersstanton]

I am not sure there is any benefit as with AC failure you are simply connected direct to the battery. 73 Peter

[@alzag6hpr553]

@@watersstanton Thanks Peter, I was just thinking if it acted as a 12v to 13.8 v DC converta that be nice.

[@jimcaddis9417]

Any update Peter on the Nevada PS? I own the nevada ps30m and that thing heats up rather fast to around 50c then the fan is on full blast, drops to say 48-9c goes off and the cycle continues. As you state the fan never came on I am wondering is this is a thing with Nevada?

[@danadkin8652]

The Nevada power supply may be a good addition to a Yaesu Dr1/Dr2 repeater. What's your thoughts?

[@watersstanton]

Perfect!

[@G0FUW]

Pete, I have had a W&S 'Power Mite' PSU for many years and it has given great service ay home and on holidays but it has recently developed a fault. Do W&S have a circuit diagram available?

[@watersstanton]

Try [e-mail], but I suspect not. These items are normally serviced by inspection as our guys know their way around this type of gear.

[@G0FUW]

Thanks Pete, I will get in touch.

[@Roddy1965]

My power supply always works. ALWAYS, because the on off button doesn't work, and it's always on!

[@watersstanton]

Can't argue with that!

[@gerl9869]

Nice video but not enough for me. I want to know more about the build quality and finish, why are there no shots of the inside? We only see closed boxes, also no measurements of any noise on the output voltage and a test of the stability under different loads. Too bad, a missed opportunity.

Linear Power Supply with twice the necessary capacity.
