Universal Compact Bench Power Supply- 30 Amp Regulated Home Lab Benchtop AC-to-DC Converter 13.8 Volt/9-15Volt, Cooling Fan, Screw Type Terminals - Jesverty SPS-30II

Good power supply. I ran 3 radios on it, a DB-40G GMRS, Yaesu FT3185Rasp, and a Yaesu FT-710. Works well, the FT710 at 100 watts is all it wants with the other 2 radios sitting idle. Very stable voltage, and not much switching noise... which you can move around with the knob on the front panel if needed. Meters are very sensitive and accurate... and the voltage control is very stable, less than .1 volt deviation when transmitting SSB at 100 watts. I replaced it with an Astron RS-35M since I'm partial to Linear power supplies, but I'll keep this one as a spare. Definitely would buy another.

I've had this power supply for a little while now and has worked well. I had purchased it to replace a more expensive one that went out. It has done a great job so far powering a radio bench with several radios. I get no power supply noise on any of my gear so it was compatible even though it has an adjustable offset. Runs cool and fan is pretty quiet and the price was in my low budget wallet range.

Very nice for your 100 wat hf radio , gives stable power out put, you can adj voltage out from 9v to 15 volts or you can put it in 13.8 v always. I recommend this to anyone wanting a power supply for the radio equipment. Also no noise into radio this is great as I had one ps that I could not use while back because of noise.

Wonderful Power Supply, does exactly what it says. All of the things work on it, the lights, the meters. The back has a 13.8V switch for HAM Radio purposes as well. Super easy to set up and use, and is extremely accurate on the product. Great value for the money, and makes close to no noise. Sits well on the table and is about the same dimensions as a radio, so fits well on the table for it's size.

Never had this brand of a power supply before but is just works very perfectly and better than I expectedIt has plenty of Amps to run 2 or 3 radios and very good on the voltage meter and the Amp metersI also like the white LED lights on the meters so you can see it quite well , and didn’t need a separate power cord to run the lights in the both meters on the front of the power supply, for the voltage and the Amperage metersI am very satisfied with this product and does more than I thought it wouldIt’s built very well and not that heavy at all and does just what I want it to doI would give it 5 stars and has more than amperage than I need

The 30 amp power supply has worked well for it's first day. The variable voltage works and is approx 9-15v, the fixed is 13.8v. The voltage meter is right at 13.8v when it's on the fixed voltage. The ammeter reads low. I have a 20 watt transceiver that I know draws a bit over 4 amps. I had never measured it before. The ammeter read 2.25 amps. So I went and measured it with my ammeter and I got 4.55 amps. So that's not very accurate and I'm not sure if it's just a low current error or if it'll be similar on larger draws. I purchased this because I am getting a 50 watt transceiver and my 4 amp power supply will be insufficient to power it. I also have issues with my former power supply when I get gabby because it draws a bit more than the power supply is designed to supply. It overheats and shuts down. I'm sure I won't have that issue with my current or new radios. Just wish the ammeter was more accurate. 3.5 stars

Runs a ic7000 no issues on 100w doesn't make any noise that I have noticed would buy again. At first I wasn't too concerned about the front power hookups but its nice to be able to charge a phone off it

Works great to power an Alpine MRP-M500 amp for a garage subwoofer! No noise, excellent quality.

Funktioniert nicht in der EU. Funktioniert mit 110 V.

Very pleased with this item. Im using it to run a ham radio transceiver. Build is high quality and the chassis stays cool, no excessive heat. It is also quiet, not generating radio noise.

All kinds of choices for power supplies . I picked this one here it seems to meet my needs. Meters all work , fairly light can handle a good load .PS again my opinion only thanks for stopping in .

My primary concern was if this power supply would create electrical noise powering my HF radio-it does not!Edit: Having used this power supply daily for about a month, I have noticed there is some switching noise on 17M, 12M, and 10M bands. The other bands from 80M to 6M are clean though. The switching noise is about 3 kHz wide, spaced approximately every 35kHz. The "Noise Offset" knob moves the noise easily if it's in the way of a signal. In practice, I have no concerns and would still buy this supply for the price.

Bought this to replace my ICOM power supply. Wanted something with meters but didn't want to break the bank. Measured voltage drop from 13.85V down to 13.44V when transmitting 100W into a dummy load. Totally acceptable. No indication of any switching noise across the HF bands.
