Product Description

Alinco DM-30 30A 13.8V Adjustable Digital Power Supply

Alinco's latest Digital Power Supply DM-30 , is an affordable switching power supply packs a lot of features including Anderson Powerpole® connectors, an ultra-compact, lightweight design that supports 9-15VDC variable output and delivers up to 30A peak power to 2-Way Radio communication products.

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, Anderson Powerpoles® connectors, 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!

 

  • The output voltage is continuously adjustable from 9 to 15Volts 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 Anderson Powerpoles connectors on the front panel quick plug-in/out as well as adds an extra versatility.
  • The Noise Offset Circuit moves unwanted switching noise to another frequency.
  • Designed with reliability in mind, a durable cooling fan keeps DM-30 running continuously under heavy loads.
  • The Rear main output terminals are large enough to provide an efficient Max 30A power transfer to your equipment.
  • Input voltage     120VAC 50/60Hz

  1. Seems like a good power supply for tor the money. 4 Star Review

    Posted by on 31st Jul 2018

    The DM-30T seems to work fine. I measured max voltage setting at 14.98 volts and min voltage at 7.92 volts. Preset 13.8 volts actually delivers 13.76 volts. Current metering accurate enough. Voltage regulation seems good. I checked for RF birdies on power leads using Rigol Spectrum Analyzer and seems clean but if there is an interference issue, there is a Noise Offset adjustment, however, probing inside with cover off, the switching frequency was measured at 27.4 kHz. Harmonics are generated a multiples of this frequency but should not radiate outside the box. Interesting, the Noise Offset control didn't change switching frequency until set fully clockwise when it abruptly changed to 33.1 kHz. Said another way, there was no gradual change in switching frequency with Noise Offset adjustment. Like another review, I had to re-configure the position of Anderson Power Pole connectors on front panel to match standard used by "Rig Runner" distribution panels and cabling I use in my shack. Fan noise did not seem objectionable.

    Seems like a good light weight, high capacity, power supply for the money but just a little concerned that switching frequency does not change gradually with rotation of Noise Offset adjustment. Is this the way it was designed to operate? With no birdies emanating, however, this should not be an issue.

    I am very pleased with the ALINCO power supply. The bright display of V and A is a real plus in my setup.
    MTC shipped within 24hrs and I am grateful for their super Customer Support.

  3. Excellent bench radio supply 5 Star Review

    Posted by on 25th Jul 2018

    The features of this power supply are excellent: fixed/variable voltage, noise offset circuit, Anderson PowerPoles on the front (reconfiguring is very easy: remove the front panel holder from the case, remove the roll-pin, remove the powerpoles from the front panel holder, correct the configuration, re-insert the powerpoles into the front panel holder, re-insert the roll-pin, re-insert the front panel holder into the case, & done...I painted over the "+" & "-" indicators, but that's just OCD me !!), & the meter, which to me is one of its absolute best features !! I personally have no problem whatsoever with regard to the fan noise, even at my 20A+ full load operation. I would definitely recommend this power supply to others, especially at the MTC price.
