  • I absolutely love this bench power supply
Size: 50II(5-19V 50A)
I am extremely impressed with the Universal Compact Bench Power Supply – 50 Amp Regulated Home Lab Benchtop AC-to-DC Converter! I actually purchased two of these units, though I’m currently using only one, and it has been performing flawlessly powering five radios simultaneously in my shack. This power supply is a game-changer for anyone running multiple devices or building a home lab setup. The build quality is excellent—it feels solid, well-engineered, and professional. The voltage and current regulation is very precise, which gives me complete confidence that my radios are receiving stable and reliable power. Even when all five radios are running at the same time, there’s no noticeable voltage drop or instability, which is incredible for a single supply. I also love how compact and user-friendly it is. The front panel controls are intuitive, the digital displays are clear, and adjustments can be made quickly without any guesswork. This makes it easy to monitor voltage and current in real-time, which is especially helpful when I’m experimenting with different setups or testing equipment. Another feature I appreciate is the versatility of this power supply. It handles a wide range of devices and loads without issue, and it provides clean, regulated DC power that’s essential for sensitive radio equipment. I’ve noticed no interference or noise being introduced into my setup, which is critical when running multiple transceivers at once. Overall, I absolutely love this bench power supply. It’s reliable, powerful, and built to last. For anyone running multiple radios, doing electronics projects, or needing a dependable regulated power source, this unit is a must-have. I highly recommend it—and honestly, I’m so satisfied that I’ll likely start using the second unit to expand my setup even further! Easy to connect, great quality, great value. ... show more

  • PROVIDES A LINEAR AMPLIFIER WITH A FULL FIFTY AMPS AT 12.5 VOLTS FOR A COOL 300 WATSS OUTPUT
Size: 50II(5-19V 50A)
THIS IS A NICE FIFTY AMP SUPPLY. TO LIKE} Attractive well made heavy weight Good design features Dual Meters for Voltage.... (adjustable) Lower current 12V. Cigar plug receptacle on front panel for Hand Held, or Other. Good heavy power cord. Solid attachment to supply good solid mating. I have been using this power supply everyday for twenty four hours a day at standby condition, and power up for at least one half hour for a weekday netcall. It has performed flawlessly. Stable, extremely accurate voltage control once set. It is a solid piece of gear for my VHF equipment in my Ham Radio Station. I know my equipment since I have been a radio amateur a bit longer than most, I once held an FCC First Class Radio Telephone license and was an FAA Certified engineer keeping all airborne heavies safe and happy. This is a very nice power supply. Gives up little warmth for a full demand load. For a HAM radio operator, or anyone wishing a good DC bench supply this Fifty Amp is great equipment for the price. You could not make one as nice for the price. I am certain of that. I am awarding the Supply a A GIANT FIVE STAR RATING. for performance and overall value. ... show more

  • Best 50 Amp Power Supply for the Money
Size: 50II(5-19V 50A)
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. ... show more

  • The 50 amp and 60 are great power supply’s
Size: 50II(5-19V 50A)
Received in new perfect condition. Works as advertised. Everything checked out. Using it now for my ham radio station. 40 amps continuous and 50 amps surge. Good size power supply and fits nicely on shelf. Very happy with my purchase. Would recommend this supply. Once again time will tell when I get some hours behind it. But for now it’s working great. I like how the meters have light on them. Light brightness is perfect not like looking into a flashlight. Also the layout of controls and connectors are very well planned out. Update, my 50 amp power supply is still working great! Plus I just received my 60 amp with LCD display. I needed more current for my two amplifiers I purchased. UHF 160 watts and VHF 350 watts. My antenna can only handle 330 watts. So I keep the High power setting at 300 watts. The 60 amp power supply works great. Just needed to update this because there were now reviews about this model. Only had this one day. But if it’s like my 50 amp, I expect it will hold up just fine. Beautiful power supply’s. Highly recommend!!!!! ... show more

  • Nice unit, quiet RF
Size: 50II(5-19V 50A)
So far it’s working great I power a couple of radios and a small hf amplifier. I have only drawn up to about 40 A but the unit itself is very nice. Very quiet rf wise and physically.

  • Works OK
Size: 50II(5-19V 50A)
Works OK and delivers 13.8 V at 25 A to my ham radio equiment. The volt meter worked at first but then appeared to stick. It read low at 13.8 V and would not return to zero. The power supply delivered 13.8 V as measured with a digital voltmeter. It now appears to be working correctly.

  • So far so good
Size: 50II(5-19V 50A)
Operates my old 1990s-era 100w transceiver without issue. I like that it generates so much less heat than my old Astron transformer-based power supplies. Time will tell if it lasts as long, but so far, so good.
