Greatest price ever. Excellent Product
The linear amp builders donât want you to know about these power supplies. They work great. I am using a 125 amp for my mobile 1×4 (2879câs) about 1000 watts. Believe me compared to the $400-500 price for a know amp builders, I encourage you to buy this instead. No hum, no noises and no issues. The fan is quiet. I attached another fan just for back up

Can’t deliver the 85% wattage without generating odor of over heating!
I liked the hardware and did not see any issues with external build. The issue was performance. I tested this with loads from 600 watts to 1000 watts. It was fine up to 800 watts, but when I increased the loading from 800 to 1000 watts, the fans turned on loud and my two car garage filled up with a pungent odor and haze cloud. It literally smelled like it was almost burning.
K.E.N. –
The 12v,125amp for long term use operate no higher than 80% by owner manual booklet.
I like it. Figured a way to use my grid tie. This 12v power source is great for it. my problem was using a 48v solar system and needing 12v for a grid tie, solution, use the output of the 48v system AC out to this power supply. Only wanted to assist the power coming in from the grid. This power supply is pumping in 30amps to the grid tie and giving about 360 watts to the grid. Needed to exercise the 48v batteries. It works.
