PR50 Time Owned: 0 to 3 months.
I recently purchased a PR50 Power supply used as the SEASIDE HAMFEST in Seaside OR. I thought I was buying a good power supply from a company that supported thier products.

I got the unit home and found that unit did not regulate well. The voltage swing was 1.5 to 2.5 volts. I figured that I could repair this unit since I have twenty years of experience as an Electronic Technician.

The next morning I called Tripp-Lite Technical Support asking for a power supply schematic, and was told that Tripp-Lite does not sell schematics for thier power supplies. I asked for help on trouble shooting this issue just to recieve a vague answer and got little or no help on where to get parts. I was told that I could replace the unit for 132.00 plus shipping.

After an hour of figuring out where the ground leak was in the supply I got power supply working with a .2 voltage swing under load.

I would not recommend this brand for the above mentioned reasons. I will never buy another product built by this company.

Poor customer service Time Owned: more than 12 months.
I had a PR-40 for about 5 years. It had a relatively light load of a single 100 watt transceiver that operated mostly CW. It started to make a noise every time I keyed the transceiver and the other day it began to overheat. I turned it off to open the case and disconnect the load. When I turned it on again to make measurements, it blew all four pass transistors and at least one transistor on the regulator board. When I contacted the manufacturer and asked to purchase a schematic, I was told that it was their policy not to supply service information or diagrams - it sure is a pain to work on these things without a circuit diagram. I informed them that it was my policy to buy another brand next time.

Great Time Owned: N.A.
I bought a PR25a 25 amp continuous in 1985. I have powered a Mirage B3016 ever since. It has not even burped. The automotive press in style diodes ar great. I opened it up this week, and noticed some leaking from the caps. I will replace them, but no hum yet. This thing has been through 3 moves, many trips to my beach house and even saved my rear when a 12 volt pwr supply went out on a Sunday night at my television transmitter where I was chief engineer. 18 years of flawless service is hard to beat.

PR-40A BTFL Time Owned: 0 to 3 months.
This power supply is very quiet and has a really cool hu-um, when it first powers up. The model I have is about ten years old and I just bought it from a guy in San Fransisco. The only draw back I can see is, this unit is a big, heavy, monster! The good news is I'll have power to spare running my HF, and VHF radios, and any thing else that comes along. Power to spare, that's my motto.

Tripp lite PR30 Time Owned: N.A.
I have used a PR30 for about 5 years now without incident. This is a big supply. About 4 times the size of my little 25amp switcher and considerably heavier. It's probably not my first choice to take along on trips, but for a shack power supply,it does the job just fine.

My only complaint is that if the supply is positioned too close to the HF rig that I am using it with, it will induce a hum on my signal. If I move the supply about three feet away, the hum disappears. It has done this since it was new. I just know not to place it right next to my rig and all is fine.

Do I recommend it? Yes

Solid performer Time Owned: more than 12 months.
I have a PR-10 that I've used most every day for the past 10 years. It's running a 12V bus in my shack that's feeding QRP gear, transverters, noise cancelers, amplifier relays, and even several back-lights behind meters in tuners. Average load current 5-8A depending upon what's running or transmitting. After a decade, it's still going strong without a hint of noise or trouble.

DIED AT 1 YEAR OLD Time Owned: 6 to 12 months.
I'm a long time fan of Tripp Lite products (surge protectors and power supplies), but my low amperage DC supply used in my shack for peripheral equipment (DSP processing, audio equalizing) died after 1 year. It took me a while to figure out that it was the power supply - -because I heard all sorts of audio pops and cracks. Then hooking up my VOM, I saw that the voltage out would jump between 12 volts down to 5 volts. Thank goodness it was a down voltage and not an over voltage situation! I'm still going to buy another Tripp Lite to replace it - - but wanted the group to be aware of this problem.

Rock solid after 8 years. Time Owned: more than 12 months.
Bought the PR25 back in 94. I have used it extensively for the past 8 years with all types of communications gear and accessories without any problems at all. Currently pushing a Kenwood 570SG and a Icom 2100H.

Over 10 years old and still rocking Time Owned: more than 12 months.
I've had a PR-40A for over 10 years. Simple, solid, quiet, reliable. I can key up all three of my rigs at full power and it doesn't even flinch.

I recently customized mine by adding volt and amp meters to the front panel. Now it's even better.

I don't know what the other reviewers are talking about -- maybe they got lemons, but mine is and has been rockin'. And, if I can remember, it was about $50 less then a comparable astron with about 10 extra amps to spare.

Don't hold up well Time Owned: 6 to 12 months.
I installed three of their 40-amp (yeah, right) power supplies on some packet nodes - running 110watt GE Delta S VHF radios. The peak current draw was 22-23 amps. The Tripp-Lites lasted anywhere from 5 to 9 months.

They are all gone now. And I certainly won't be buying any more! I have been using Alinco DM330's for the past six months or so, and haven't had any failures to date.
