Excellent bit of gear
|
Time owned: 6 to 12 months
|
Bought it from R&L to replace a REALLY inexpensive switcher (PSV-200). No problems with the Pyramid, but I wanted a solid, regulated power supply, and this one fills the bill. Cool, quiet, dependable and looks serious on the bench.
If I were to discount the rating, I'd agree with the notion that the outputs belong on the back - BUT, that's not nearly a serious enough flaw to reduce a top grade.
This one's a keeper.

Wish they still made it

Not a lick of trouble, runs my HF rig, VHF amp, qrp rig, no problems. I still don't believe switchers can be super quiet and prefer a linear power supply.

I own 2 of these and both have never given me a lick of trouble. Bought them used at a hamfest. Best buy I ever made. Quiet fan and just keeps working. One powers a FT-897 and the other a FT-900AT. No birdies, no problems.

I bought mine used about 6 months ago and it's been in daily service since. Fan is quiet, no birdies anywhere, and it runs cool. I run an HF rig, an old Kenwood 2 meter all mode rig, a clearspeech, and a small computer fan to augment the fan in my amp. Never a hickup.

Takes a Lickin' n Keeps on Tickin'...
|
Time owned: more than 12 months

I jest gotta Add my Two-Cents worth since I have been using this Alinco DM-340MV CONTINUOUSLY "ON" for THREE Years except for local power outtages and extended trips away from the shack without a single Burp... now thatz Reliability... and itz Gud Lookin' too! First the Negatives: Output Power Access ONLY on Front makes for messy wires - Non-standard Sizing makes for tricky placement in shack... Picky picky. Now for the POSITIVES: Very Quiet fan cooling - Nice DUAL Metering of Volts/Amps - VARIABLE Voltage on Front Panel to make up for Line Loss to rigs to Insure Proper INPUT Voltages - Front Panel Fuse Holder for Easy Checking - Of course, since it is Conventional Transformer Design, there is NO NOISE coming from the supply - Did I say it's Good Looking too. Although I prefer Rear Output, this unit is awarded a deserved WV4R FIVE-Star Rating because it Does take a licking and keeps on ticking. 73 es God bless, murf.

Outstanding power supply
|
Time owned: 3 to 6 months
|
This is one very solid power supply. Good looking, quiet - electrically and mechanically, and well build. Huge transformer, 4 power transistors (each one rated at 15A - capable of 60A total current, although you can draw 30A continuous and 35A peak due to the overall design specifications). For what they are going for now (under $100), those power supplies are a bargain. The regulation is smooth - 0.00 to 15+ volts - if you need a voltage output of 0.65V for instance, you can dial it with no problem (more acurate DMM is needed)!
Took me an hour, 4 yellow ultra-bright LEDs, 4 resistors, a piece of wire, and a hot glue gun to add lighting to the volt and the amp meters - schematics of the power supply are available on the Alinco's web site.
I have 2 radios and some other equipment connected to it and it works very well for me.
The temperature controlled fan rarely kicks in.
This supply is going to stay in my shack! (I own a DM-330MV - another fine power supply from alinco which i use now for portable operation)

Rock solid performer!

Bought this beauty over three years ago. Hooked cables to it and stuffed it in the corner ( with some breathing room ) under the operating desk. The only way I know it's there is that all the rigs keep working fine ( currently have a FT-100D, FT-1500 and all kinds of gadgets hooked to it 24/7 ). No complaints!

Compré una de las únicas dos fuentes Alinco que llegaron a Argentina, y creo que fue la mejor compra que hicimos con Eduardo LW4EAP.
Sobra potencia. Tengo todos mis equipos conectados trabajando las 24 hs. del día y sin problema.
Tiene una ventilación que se imcrementa cuando toma temperatura, pero a máxima potencia no genera ruido molesto.
Muy buena. La recomiendo.

Real Workhorse!

I've been using the switching power supplies until purchasing the DM-340MVT for the IC-756 PRO. This is my first linear power supply. I did not realize how may birdies even the higher rated switcher power supplies generated. The DM-340 MVT is very well constructed, the fan is very quite and you do not even know for the most part that it is running. It's a real workhorse. I've had no problems with it. It is substantially built and I feel that for the price you get much more for your money than any other brand of power supply. If your looking for top quality power supply with a few extra amps to spare, this 35 AMP supply will probably exceed your expectation.

Nice supply, but fan noise fairly nasty with just 3 amp draw.
|
Time owned: 0 to 3 months

After trying the Icom PS-125 switching supply with a Icom IC-756 PRO II, with was not a good experence at all, I tried a Alinco DM-340MVT with the rig.
Generally well made (above average for this product from china). 4 nice hefty 2SC5200 pass transistor's and a fairly good sized heat sink are found inside, with a nice large set of main binding post terminals that you can totally remove to connect your spade lugs.
We indeed have a full size internal fan that has a thermostat control. With just a 3 amp draw from the PRO II in receive, the fan is quite noisy. Now at a lower current draw it's not as bad. I don't mind a noisy fan in transmit, but it bugs me when just in receiving mode.
I'm working on simple modification for this fan noise (resistor change of R30), and will post on my web page if it comes to be useful (web link below).
Only other comments are , I wish the main binding post were on the rear . A nice 3 wire detachable AC cord (only has a straight wired 2 wire cord), and lighted metering would have been nice.
But overall a nice supply and for the $$$'s spent is a OK supply for just about any radio.
