The Alinco DM-330FX 30 Amp Switch Mode Power Supply With USB Ports, This switching power supply packs a lot of features into a compact, lightweight design that features 9-15VDC variable output and delivers up to 25amps, 30 peaks. Unlike other "switchers", it's electrically quiet. But if you should find noise, don't worry! The patented Noise Offset Circuit lets you move the switching noise you might find to another frequency. Other features include a large illuminated "instrument-class" Volt/Amp meter, rear panel binding posts (30A peak), front panel cigar outlet (10A), two pairs of snap-in terminals (5A max.) and USB ports (2A max.), front panel voltage adjust, customer-defined output voltage "memory", ripple less than 50 MVP-p and triple circuit protection for short-circuit, over-temperature, and current limiting.
