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.
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 .
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.
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!)
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.
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.
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
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.
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.?
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?
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?
