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

I have had this power supply now for several months and it works as advertised. I like that it has two LED lit dials, one for amps being drawn and one for voltage. I have mine set for 13.8 volts DC as recommended by most amateur radio gear. When transmitting with my HF or VHF transceiver at 100 watts, the voltage does not drop any nor does the needle even flicker. The amp meter does show the proper amount of amperage being used. The fan does NOT run constantly like a lot of the switching power supplies do. It is a very quiet power supply. The fan will come on if I am running high wattage on 100% duty cycle modes of transmission. The fan runs only until the unit cools back down and the fan is not very loud. The unit has a voltage adjust knob on the front along with an offset knob for moving any "birdies" that the power supply might generate, but I have not found that to be a problem. There are also two sets of Anderson Power Poles on the front along with a cigarette lighter type outlet. The main power is supplied through two heavy duty connectors on the back of the unit. I do highly recommend this power supply for a radio amateur and the price is the best around for a 50 amp supply.

Works great. Powers my solid state amp no issues. And quiet.

Works great, just what I needed to test out 2 reverse cameras in my living room before heading out to the truck. Always wanted one, and this is a nice unit.

I ran the output on my O scope and the waveform was smooth as glass and ripple free. I ran it up to 80% output power and it did not even slow down. No bogging down and no excess noise or spurious radiation interfering with other audio systems. Great Value. Will be buying another one soon. Five Stars

This power supply has worked great for my HAM shack. Powers 3 radios with no issue. Unit is quiet and produces no noise in my recieve or transmit signals.

Does the job. Accurate , quiet, dependable.

Running this on a Yaesu FT847, works well, plenty of reserve power at 50 amps. No noise, and otherwise works fine.One issue, also mentioned by others is when you shut it down you get the odd voltage pulsing as it turns off. I try to shut the radio off first, but I don't always remember. Does not seem to be a problem, but would be nice if it didn't do it just for piece of mind.

Needed it for my Electronics Laboratory Bench.
