About this item

  • 【Voltage Control】The output voltage is continuously adjustable from 9V to 15V or set at a fixed 13.8V. The Noise Offset Circuit moves unwanted switching noise to another frequency.
  • 【Screw-type main terminals】The main output terminals ensure easy compatibility with all DC-powered devices and are large enough to provide an efficient power transfer to your equipment.
  • 【Auxiliary Output Terminals】2 pairs of auxiliary snap-in terminals and a cigarette lighter socket on the front panel for added convenience.
  • 【Analog V/A Meters】Highly visible V/A twin meters for real-time monitoring of the status.
  • 【Forced Air Cooling Fan & Protection】A built-in cooling fan that prevents overheating and keeps the unit running continuously under heavy loads. Advanced short circuit protection and automatic current limiting ensure the safety of operators and any connected electrical equipment.

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

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.

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.

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.
