I own 2 of these, 1 purchased from the big auction site, 2 from Amazon. The first one was DOA; popped a fuse as soon as I plugged it in. The second one had a dead fan controller (fan NEVER kicked in). I returned the first, but the second wasn't a deal breaker for me since I planned, and did, put a bigger quieter fan on right away which I let run full blast. The stock fans are VERY loud when being used for radio equipment.
One major thing to look out for; both of the units I purchased from Amazon were set in the 220v position by default, plug it in with the switch in that position and you WILL fry the power supply and potentially damage anything attached to it. Double check when you receive yours.
Thanks to Amazon's no hassle return policy, I will continue to purchase them knowing I can send them back if they're no good.
- Can handle short bursts above the maximum rated output.
- No discernible RFI.
- Easily adjustable between 11v and 15v; doesn't sweat running at 13.8v.
- Fan is loud.
- Line level switch is 220v by default.
- Quality control is poor.
It was also able to provide over 37 amps at 15.3v.
Fan is not variable speed on mine. Perhaps two speeds, but the slow speed is only with Zero load, put 0,03 amp load on it and the fan fires up to full speed which seems excessive at amp loads under 10 as the thing barely gets warm.
Will update if it does not stand the test of time, but I plan on improving fan.
it is much smaller than envisioned. Was set to 220 from the factory and before adjusting, the voltage pot was at 12.77V.
Pot range of motion is less than 180 degrees so it takes micro adjustments to get it to a desired single decimal place and to the hundredth of a volt is extremely difficult.
The Fan is 60MM, not sure of the thickness yet but suspect 15mm. Expect Edits if it fails.
Edit: When providing Over 36.2 amps the unit began to buzz. Reducing voltage on the trim pot would allow one to hold amperage under 36.2, but as battery voltage rose, amps tapered requiring moving the trim pot up to keep it close to 36 amps.
17 minutes of Buzzing and the magic smoke was released. There is no overload protection circuitry within.
I expect this would have been fine providing 20 amps all day long. It was barely warm at 15 amps, but a large depleted battery can overload this device easily, and did so, and I stress tested it to provide that 17 minute number. I had increased airflow and made the internal heatsinks mate the casing better and used thermal grease to extract heat from the 4 main transistors, so i expect 17 minutes was a bit more than the standard unit .
I'm replacing it with a Megawatt or a Mean well which claim to have overload protection circuitry to keep the magic blue smoke safely contained within.
