|I have several solid-state amplifiers that require 80 amp's at 13.8 volts, and have not used them because I have never had a power supply large enough to power them. I had tested them out with large tractor batteries, but I don't like the use of batteries, so my amplifiers remained unused.|
Last week, while browsing through Martin Lynch and sons website (London), I came across this power supply. It looked like it was just what I needed. I went ahead and bought one, and had it flown out with UPS. It arrived this morning - I was impressed with it's build quality, large and imposing, with two fans on the rear. I made up some heavy duty cables using welding cable, to go from the power supply to my Ameritron ALS-500 amplifier, and started testing into a dummy load. The power supply loafed along, supplying 70 amps with ease, which got the amplifier to 550 watts. I was really impressed how quite the power supply was, the two fans run simultaneously, but are whisper quite.
Next test was to scan the bands to check for any hash generated by the supply - nothing, I was unable to hear any noise generated by the supply on any band.
Although fairly large, it is not too heavy, being switch mode, and looks really neat on the operating desk. The front panel is un-cluttered, which I like - I don't like power supplies that have their outlets on the front, it makes for an untidy installation.
I am happy, and now I can make good use of my solid state amps that have been in the closet for so many years. I have only had this for one day, but on first impressions, and with test that I have done, I can recommend it.
