This CE-Approved, affordable switching power supply packs a lot of
features into an ultra-compact, lightweight design that features
9-15VDC variable output and delivers up to 20A continuous, 30A peak.


Convenient for radio users, the Noise Offset Circuit moves unwanted switching noise to another frequency. Other features include a large illuminated digital Volt/Amp meter, rear panel binding posts (30A peak/a pair), front panel quick
terminals (5A peak/a pair, banana for E, Anderson power Poles for T), voltage adjust (9-15V) or fixed at 13.8V, ripple less than 80mVp-p and triple circuit
protection for short-circuit, over temperature, and current limiting!
