Im using them in a security system that needs 24VDC and they works very fine, used to have more expensive PS installed but for just 14$ i have a nicer PS and more powerfull. With a 3A load (72W) the voltage drop is only 0.1VDC (Electronics equipment) With a 4.5A load (coneccted to my CNC) the voltage drop is only 0.3V and measured with a oscilloscope the supply still a flat line, so its perfect. It doesnt overheat, maybe 35ºC with heavy load, so will last a long time. Comes with a circle hole for ventilation, with a metal mesh, but not fan inside, just convection cooling. Does not come with 220VAC cable, but any cable from a PC power supply fits nice. DC cable is near 1m long, thick enough for 3-4 A currents and with a standard DC connector. Bought 7 and all works nice. Reselled some with nice benefits
ótimo produto
worked out of the boy. You can see a little LED inside. The fan won't turn on unless there is a heavy load.
Parece boa qualidade. Testei-o a 4A e a voltagem caiu para 22,1V, o que é aceitável. Veja a foto da placa de circuito
Bom produto. Funciona de acordo com as especificações. Chega sem o cabo de alimentação, mas a descrição não mostra que sim. A imagem em anexo mostra que fornece 23,7 VDC sem carga.
ótimo produto excelente quantidade.
Very Good, Susper Thanks
ok
Seems to work okay
Great little power supply for colloidal silver maker. 24 volts is great for this system, but if you use 30-32 volts it will cut down the process time buy a couple of hours. Still it will work fine, just set it and forget it. You just cant beat the price, 14.00 is a steal for this little power supply. I will grab another for the in laws, so they can make their own supply, instead of using my 300.00 bench power supply. Thanks banggood Stephan
