power supply survey

[piggin]

Please post the power supply you use for your home station. And if you can the voltage and current supplied.

 I have various supplies here but primarily use Astron 35m power supplies. I have a couple of them for ham and gmrs use.

  I heavily prefer linear supplies because I can service and repair them. YMMV so what do you use?

I use a Samlex SEC-1235P-M:

13.8 volts at whatever current the radio plus other accessories plugged into a powerpole distribution panel require at the time (up to 30 A continuous).  It’s small and lightweight. When my ham radio is set to 100 watts the power supply current meter shows 23 amps.  It has a fan that comes on sometimes that is louder than I would like (any fan would be) but that’s a minor whine.

I am running a R&L Electronics 30 Amp power supply for my GMRS and dual band radios and a Tel-Power 50 amp power supply for my 100 watt HF radio and LDG auto tuner.

I leave both set at a constant 13.8 V output. The 30 Amp power supply is fine for both 50 watt radios since I never transmit on both radios at the same time. I had to go with the 50 amp power supply for my HF setup. I was running a n Astron 30 amp power supply but it wasn't enough for the radio and auto tuner and would go into protection mode.

For those looking at getting a power supply, remember that most manufacturers rate them at the maximum amp draw and not the constant amp draw. So a 30 Amp power supply will really only give you between 22 and 24 amps of continuous  power.

I would like to switch to linear power supplies but they are definitely more expensive.

80amp continuous rv power supply. Adjustable voltage from 12-16volts. I run it at 14.1 all day. I can transmit on a 50w a 40w and a 20w radio all at the same time as well as a 12v led light strip and have no loss of power.  Been running it for years, good clean power zero noise.  and at $100 I can toss it in the garbage if something happens to it.

I'm running Mean Well LMRs with a 30 and 50A outputs

I use DuraComm because they offer a wide variety of mounting types and their supplys are stable.  The last Maxon repeater i built i used their chassis mount supply

Alinco DM-30tr here...it has a switch for straight 13.8v or variable that I leave set to 13.8. rated for 20a continuous, 30 peak; it's been powering my shack since 2020, and at one point had 3 radios hooked up (2 single band Vertex for 2m & 70cm, and a BTech for GMRS).  Currently I just have a dual band yaesu hooked up. I also occasionally use the power poles on the front, either adapted to a 12v socket or direct, for low power needs.

  It's also not quite enough to run the HF radio at full power (which wants 22a, per the manufacturer), but I haven't gotten around to setting up a permanent antenna for that so I don't use it indoors anyway; have a couple batteries I use for that.

As @WRYZ926 mentioned, watch the ratings; most manufacturers just list the "peak" rating, and the continuous is a bit lower once you dig into the specs (and they vary how much lower), but a few actually list the continuous number.

You can figure that the continuous power output is between 75% and 80% of the advertised peak output. This will differ from one manufacturer to another. Some are 75% while others are 80%.

Astron 35 with updated digital amp/volt meter.  35 amp, up to 15 volts, run it normally around 13.6v. Powers my FT-450D and DB-20G.

Nothing special here Pyramid Universal Compact Bench Power Supply - 4.5 Amp Regulated Home Lab Benchtop

Not sure how accurate the output voltage is because my radio says 14.0 volts.  But it seems to be pretty stable.  I've seen 14.1 on occasion.  Just enough for my 20 watt Wouxun XS-KG20+
