Just food for thought here. I use those HP server power supplies. One that would suit your needs is the 450 watt HSTNS-PL14
Rated at 38 amp/12.0 volt.
They need a simple mod to turn them on, plus a simple mod to bring the output up to 13.6/13.8 volts. I derate them and call them 30 amp
continuous. On my bench, a 750 watt version has been running everything for four years,flawlessly.
The 30 amp job can run a 150 watt HF rig, probably for years. The noise it generates is just a small bit over a straight battery. There, but insignificant.
The size is 10 inches by 3.75 inches by 1.6 inches. Fully protected from overvoltage, current, and temperature.
Nice part is they can be had used for about $10.00 US. A couple $$ for binding posts, or even a nice project box for another $25.00
Best bang for the buck, I have ever found.
