We're to start with one..... Biggest problem the casing is metal,,, and its NOT directly connected to earth in fact if you measure the resistance its 1.6ohms but its being earthed through a very thin wire connected directly to the PCB, the track is running around the edge of the board and is touching the metal bracing inside holding the PCB in place, this is not a way to earth a piece of equipment and is DANGEROUS, under a fault condition the metal casing may become live!!!!! The plastics feel very cheap and some of the tracks on the secondary side of the transformer are a bit too close to tracks on the primary mains side.
That said it does work, and seems to provide 10A of current, its just that it needs the earth bonding tiding up, but given the cheapness of it I'm not sure how this will last.

Multiple protection The safety of our customers is our most important thing! K3010D DC power supply can provide a variety of protection, because •Constant current protection •Over temperature protection • Overvoltage protection •Current limit protection |
Intelligent Cooling Fan Cooling fan will intelligently turn on when the working temperature is more than 122℉/50℃, giving the device longer service life |
Compared with other competitors, Safety is our priority.We provide a high quality set of jumper or tester lines. Please refer to the main figure for detailed parameters. These are good sturdy leads with nice rubber insulation cover and the alligator clips made of copper.The clips had insulators to reduce the possibility of accidental shorting. Good quality leads that work great for moderate to low current testing. These wire are good for up to 15 amps maximum. They are fine for basic electrical testing for things like automotive accessories, as long as whatever you are testing uses a fuse of 15 amps or smaller. |
