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!

Voltage Control
The output voltage is continuously adjustable from 9 to 15 Volts DC, or fix It at rated 13.8V.

Noise offset 
The Noise Offset Circuit moves unwanted switching noise to another frequency. 

Volt & Amp Meter 
A highly visible, accurate digital Volt / Amp meter allows real-time monitoring of the output current. 

Auxiliary Output Terminals (5A max.) 
A pair of quick terminal on the front panel adds an extra versatility. 
(Banana terminals for E, Anderson power Poles for T)

Forced Air Cooling 
Designed with realibility in mind, a durable cooling fan keeps DM-30 running continuously under heavy loads. 

Large Binding Posts
The main output terminals are large enough to provide an efficiente power transfer to your equipment.
