MPN: KA3005D. Item model number: KA3005D. Manufacturer: Korad Technology. The built-in quiet variable fan reduces the operational noise and prolongs the life of product. There is also a lock button to prevent accidental changes.
I have several power supplies at my disposal already, and I very impressed with the quality of this unit, model KA3005D, it's very solid, with a sleek view, but most important still, it's performance.
I tested its output, and it remain constant within just one tenth of a volt, from .5 to 30 volt range, current also held up just fine, all within its specs.
The only thing I found to be NOT true, is the claim that the cooling fan is automatically controlled by temperature changes, when in fact, the fan starts running the second the power is turned on, it does run at a slow, quiet speed, so it is not much of a nuisance.
Other than that, it is a great unit for the price.
Works great, no problems so far. Fan is a little noisy when it first comes on. The output on/off switch on this model is the reason I bought it instead of the other cheaper models that are listed.
