Its programmable settings make switching between voltage and current requirements a breeze, while the overvoltage protection and current limiter features offer peace of mind. With its exceptional quality and value for money, this power supply has truly become an indispensable tool in my tinkering arsenal. So, fellow tinkerers, fear not! Embrace the power (supply) and let your creative projects flourish with the Hyelec by your side.

I understand from other reviews that the output on off doesn't really turn it off completely (looks like a capacitor is across the output after the on-off or something, couple 20-40mV with no load). In practice though it works very well and it's been really nice having a simple adjustable bench power supply in the typical form factor. Has been reliable so far and seems relatively accurate when measured with my HP 34401A

My go to Power Supply, even though I have many. Easy to use, and very versatile. I even use it to charge my 12V sealed lead acid batteries, set the current limit to a c10 rate and the voltage to 13.8V and it just works. Runs nice and cool and is easy to use. And with all this said, I am picky, I even have a $1200 HP lab supply and use this one much more often.

Device looked used due to cosmetic imperfections (white knobs had black marks) but close inspection indicates it’s just poor workmanship. Power up was fine. Initial voltage precision is always PLUS 0.010v. Doesn’t matter the voltage and that is an open test. I’ll add light and heavy loads later to validate. Using a 12v integrated current limiting diode, tested both C.V. And C.C and under 20ma it behaves properly and precisely. I did not verify the current surge notes by others upon “output” button activation. I’m sure it’s there. The fact I used a current limiting diode for test defeats all ability to detect a surge.Will be using exclusively for filament heater on vacuum tubes. It is far more precise than I really need.We will see how it behaves with a 4A load in a few days.

There are endless cheap power supplies on Amazon, but this is the only one I’ve found that actually works the right way. Most of the cheap switchers have a knob to set voltage and a knob to set current limit, but no markings to be able to see what they are set to. This means that flipping on the power supply will result in it outputting whatever the last voltage was set to. If you don’t remember, that might result in your device blowing up! Also, the current limit is set by shorting the leads, which means that they must be disconnected from the load to configure it.This power supply shows the set voltage and current - before the power is enabled. When the power supply is turned on, the set voltage and current is displayed, but the output is not enabled. This means that the risk of destroying whatever it’s connected to is minimized, because there is a visual confirmation of the values (just like my 60-year-old Q-Nobatron, which has voltage and current set pots - with scales).Once you are sure that the settings are correct, you simply push the output button, and watch the lights. The power supply has some bells and whistles (like settings memory), but I’ve never really seen them as being very useful.I like this power supply so much that I bought two of them.

I like almost everything about this power supply. The output voltage is extremely accurate throughout the range. Load regulation is good, noise is good enough, changing settings is intuitive. It's silent when not working hard, which is a relief compared to my noise Tektronix power supplies. The only downside is the turn-off voltage (a steady +17 mV on my unit), which isn't a problem once you know about it. At this price, it's an amazing value. I expect to buy more of these units.

After many months of testing and use at various voltages, this power supply meets all challenges with ease. Would definitely buy again.
