DC Power Supply Variable, 30V 10A Adjustable Switching Regulated DC Bench Power Supply with Intelligent Charging Mode, 18W USB Interface, Precision Encoder Knob (Black)

I have used this a lot and I really like it. The value was good, and it seems to be holding up well to my occasional use. I do not use it every day. The voltage adjustment is easy on this unit. The cords seem like they are good quality, flexible, well made. The display is plenty bright and easy to read. I would recommend this to a friend and if mine ever goes bad, I would not hesitate to buy this again.

Perfecto. Muy buena calidad

Very useful and works just fine. Voltage is not exact even at just a few volts, but seems to be very stable. Lack of instructions is significant, but after spending some time with it things begin to make sense. Rated 4 instead of 5 because of the almost entire lack of instructions.

Fantastic power supply. Very easy to use and so far very accurate. I was suprised how light weight it was for its size, I guess I expected some heavier components.

Great Power Supply for its Operating Range.

To begin with, you're not going to find a power supply capable of supplying 60V at 5 Amperes anywhere below 4X the price this puppy is sold at !!! Hands down the best deal on the market. At $75 each, I'm actually looking to buy a second unit rated at 120V, 3A. Initially I was looking at Power supplies with dual or triple outputs, but they were all no less than $350 each - especially at current values of 5A or higher. This is the best deal for the $.There are a few small issues that I would hope the manufacturer will address quickly to make these units absolutely perfect. The dials are missing any VISIBLE tick marks (or at least the half way tick marks) on them - The tick marks that you see on my photo attached here - I had to paint-on myself after calibrating the ranges on both the voltage and current knobs. This is very important when setting an exact Voltage level or a Current Limiting value in CC mode or CV mode and always running out of the fine adjustment range because you have no idea where your fine or even coarse level marks are on the dials. Easy fix for the factory, but an important one for the customer.Secondly, the spacing between the ports are non-standard for any BNC-type banana plugs! This has absolutely no affect on the performance of the unit, but for those engineers and technicians who may have dozens of BNC banana connectors to re-use (instead of buying new ones) they will NOT fit as you may see on the picture! This would be a minor fix at the factory level, but an important one for many customers who have dozens of banana connectors to re-use.Finally, there is NO push-button to disable supply to all outputs if necessary without turning off the entire power supply. The only way to do that is to turn off the power supply. Presence of This option alone would make this unit an excellent supply for the money!Otherwise and excellent little power supply at a price that can't be beat for such high supply currents at high voltages !

Excellent product, I bought it for setting some relays and it works great, quite accurate! It has an extra feature that others may or may not have: It shows the AH capacity while charging the battery. I have a deeply depleted battery and trying to revive it by performing the trickle charging with constant low amperage (as shown in the picture).

Works great but took a bit to figure out how to recharge cordless batteries with it. It kept telling me it could not charge a battery until I figured out the button sequence. I was able to recharge and restore my non-chargeable Milwaukee M18 batteries.
