I'm very satisfied
product is crap. works good for low voltage aplications such LED strips and so on.. For my 6000W inverter does not work because device is dimensionate for 500A 1,5V not for 75V Internal has 2 parallel irfp4368 MOSFETs. Opened datasheet on this transistors you see its safe operational area. And safely this device works with pulsed curent. With DC curent it has a small operational area.. Sory, but for that price i await quality.
