SS-30P 13.8V 30A DC Regulated Universal Compact Bench Power Supply, AC-DC Power Converter, 20W USB & Type-C Quick-Charge, Anderson Connectors & 1/4 inch Bingding Posts for HAM&Amateur Radio

This is probably one of the smallest 30 amp regulated supplies I have ever seen. That doesn't mean it isn't high quality. This thing is built like a tank and a peak inside shows very high quality parts that are laid out well. My first reaction was I can't believe this is made in China. Quality control was up there. Even the cabinet is made from thick steel. When you pick it up, it has some weight to it because of all of this. Most switching supplies feel fragile and light, not this thing.

The SS-30P is packaged in a glossy printed box. The PS is encased in a plastic bag and supported at each end by dense foam end plates for protection. The power cord is in its own plastic bag. The front panel is machined aluminum and the switch and connectors all fit perfectly. The fit and finish of the cabinet is first rate. The rear binding posts are robust and of very good quality. Upon power on there is an audible fan surge of about 2 seconds, and then silence. No load out of the box, the output measured 13.81 volts. It is powering my Icom IC-7300 and an MFJ-929 automatic antenna tuner. In receive mode, which draws a bit over 1 amp, the PS output measures 13.73 volts. In transmit mode, full key down CW at 100 watts output, the current draw is about 21 amps and the PS output measures 13.60 volts. I am a 100% CW operator, and the PS is extremely quiet. The fan has never run at a speed higher than a bare minimum, and it is essentially silent. It is quieter than my old Astron 35 amp linear power supply, which likes to hum constantly, even under no load, and is ten times the size and weight. The PS-30P is barely warm to the touch after operating sessions. I have about 60 hours of "burn in" time on the PS-30P. I have detected no switching noise or birdies on any of the amateur bands, 160 meters through 6 meters. It appears to be well filtered. I think this power supply would be hard to beat at this price point. Everything about it, including its packaging, exudes quality.

It's simple - buy this power supply if you want something small (I mean seriously, its TINY) that puts out EXACTLY the described voltage - no fuss, no nonsense, no fluff.A fellow ham and I both purchased this product in early November, and it was changed shortly after we purchased it to a version that includes 2 USB ports on the front. This is a great little addition, but it really doesn't add a ton of value IMO. I chose this PSU over others primarily because I couldn't find many others that offered power pole connectors in the front, along with banana plugs/ring terminals. If balanced correctly, one could run 4 different radios from this PSU (of course, only transmitting on one at a time to prevent overloading it).The ONLY minor (tiny) gripe I have, and this is more a gripe about powerpoles, is if you have two cables stacked on top of each other with the black sheating on them, it is pretty hard to take them out of their socket without jiggling the cable above or below. I think this product could be improved by just adding 1 or 2mm of vertical spacing between the two ports, if possible. That would make it a 10 out of 5 star product, seriously.I have yet to hear the fan on this PSU turn on even once, except during startup, and it handles everything I throw at it. If and when my ham shack expands, I will absolutely come back to buy the latest offering from this brand - please keep putting out your excellent product!

As u can see, it's actually smaller than my gmrs radio. So far no rf interference for 11 meter.

Using this to power a 50 watt radio and a 100 watt radio. Been working really well even when both radios are on. I have not transmitted on both at the same time, but no interference or issues with either radio when transmitting on the other radio.

I've been running two VHF/UHF radios on this power supply, with my HF rig sitting within two feet. So far, I haven't experienced any unwanted noise with the exception of the fan spinning up and down on power up. I have had it hooked up to my HF rig recently just to double check for noise and I still haven't had any noise coming from the power supply. I haven't had a long QSO with the HF rig to heat up the power supply, but I have talked on one of my VHF radios that outputs 80 watts for an extended period of time and I didn't notice the power supply getting more than slightly warm (the radio got very warm! All heat sink, no fan.). So far, I have been impressed enough with this power supply that I have ordered another one to run my HF rig.If I start having any issues with the power supply, I will add an update.Oh, yes... read the fine print, this is a 25 amp continuous power supply, 30 amp max. I have noticed a small voltage drop in mine when transmitting at 80 watts FM. The voltage drop was very minimal (0.1 volt) at the connection point when measured with a volt meter. The actual voltage reading was 13.80 volt no load, and 13.69 volt with a load from the 80 watt FM key up. That is about a 14 amp power draw.Having the power pole connectors was a great bonus, they allowed me to have both 2m/70cm radios hooked up and scanning while still having the rear connector available for other uses as needed.Good luck on your power supply quest, mine has ended here and with satisfaction! 73s...I've been so impress with the first one I bought, that I bought a second one as a spare/backup.I have it inline "cooking in" as they say.The voltage output is spot on at 13.8 volts according to my VOM and running two VHF radios.Now if I can just find an excuse to purchase a third one... 73s...

Used it to power an Apache G2 SDR radio, hoping it would not generate spurious radio signals that many switching power supplies do. Tested on 14 MHz, a complete test over the whole shortwave spectrum, but there was no detectable RFI.
