Alinco DM-30E (20 Amp) Switch Mode Power Supply


This CE-Approved, affordable switching power supply packs a lot of features into an ultra-compact, lightweight design that features 9 – 15 VDC 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 80 MVP-p and triple circuit protection for short-circuit, over-temperature, and current limiting.

  • The output voltage is continuously adjustable from 9 to 15 Volts DC, or fix it at rated 13.8V
  • A highly visible, accurate digital Volt / Amp meter allows real-time monitoring of the output current
  • A pair of quick terminal on the front panel adds an extra versatility. Banana terminals for E, Anderson power Poles for T
  • The main output terminals are large enough to provide an efficient power transfer to your equipment
