Universal Compact Bench Power Supply - 30 Amp Regulated Home Lab Benchtop AC-to-DC Converter for CB/HAM/Amateur Radio with 13.8V Fixed OutputScrew-Type Terminals, Cooling Fan - SPS-1330

This is a great power supply for ham radio! No fan noise, and no RF hash in my radios! A very cost effective power supply with Anderson power poles which make it very easy to hook up to my radios, unlike my other power supply's that have banana jacks. This is now my go to supply.

I DECIDED TO PURCHASE THIS INVERTER FOR TWO REASONS ONE IF IT EVER GETS HOT ENOUGH IT HAS A FAN THAT WILL COME ON AUTOMATICALLY AND TWO FOR IT BEING 30 AMPS. I GOT IT TO POWER MY CB RADIOS AT 13.8 DC VOLTS AND IT DOES ABOUT 14.1VOLTS WHICH IS GREAT FOR WHAT I WANT IT TO POWER. I HAVE A 40 CHANNEL CB AND 100 WATT KICKER AND THE FAN HAS NEVER COME ON SINCE I PLUGGED IT IN TO USE IT. IT IS WHISPER QUIET AND NO INTERFERENCE COMING IN THE RADIO FROM IT. ALSO THE UNIT ITSELF HAS NEVER GOT WARM TO THE TOUCH EITHER, LIKE FROM OVER DRIVING IT. SO IF YOUR WANTING TO SET UP A CB BASE STATION IN THE HOUSE, DON'T OVER LOOK THIS INVERTER WHICH IS SMALL AND OF GOOD QUALITY GOOD VALUE AND PERFORMANCE AND WHISPER QUIET. IT DOES HAVE A FUSE AND THAT WILL LET YOU KNOW WHEN SOMETHING ISN'T RIGHT JUST IN CASE. OK THEN I'M DONE. 73'S--027TAMPABAY..

I like this little supply, and it is little, small and light. This is my first switching supply. I always liked the ones with the big, heavy power transformers. I am using it to power a vhf ham transceiver, which draws 20 amps on high power. The supply provides this effortlessly, does not get hot and the cooling fan has not kicked on at all. There is no radio noise from the unit. I can vary the voltage from 9 to 15 volts, but I just leave it on 13.8 and it stays there, with no lag under a 20 amp load. I like having separate voltage and current readings, and they are large, bright and easy to read. I really have no complaints, but it would have been nice to have a second pair of power jacks on the back panel. The single pair of back panel connectors do not appear to be particularly heavy duty for a 30 amp connection.

I've had this power supply for a few months and am very pleased with the purchase. My previous power supply for my ham radio was noisy. When I transmitted, you could hear the fan in the background. Not so with this power supply. In fact, it is so quiet that I forget that it is turned on. Fortunately, it does not draw much current when the load is off. I preferred Anderson Powerpoles on the back, but the banana plugs are OK.

For the money it's not a bad power supply it's not 100% completely noise free but it's much much better than most on the market say like pyramid. The power supply had before this was a 30 amp pyramid and man was it noisy all over the HF bands.

It works good

Great little PS. The PS I had for my transceiver was giving me birdies (harmonics) on certain frequencies. This PS (SPS-1332) is really clean as far as harmonics. I do have little ones on 80 meters, but just touch the noise offset knob and they are gone. Good value and build well. Best PS for Ham transceivers under 30 Amps.

The power of the product is very strong, great voltage stability. The functionality is very strong and it blends right in can’t even tell what it is..
