Common Questions
Is it possible to adjust the voltage up to 16v after plugging in, because the device voltage drops to half of my set voltage?
plarity is correct, make sure it's correct.
Is it normal for it to spark when I plug it in?
It's normal if the knob isn't in the off position, but I recommend you plug in in in the following order: make sure the knob is in the off position.
Can it charge a 24v 2400 mah battery?
It's a power supply, not a charger, and if you're trying to charge a battery by connecting it directly to the battery, it doesn't have the proper logic or current control.
Is there an output setting for 3a 22v or 66W or does it only go from 20v to 24v?
You can choose between 3V to 24V max, and I use it for my pond pump which is max 18V, and I typically run it at 10V or so.
Is it possible to change polarity?
There is an adapter for that.
