Harley Benton PowerPlant ISO-3AC SAG Modular

The brushed aluminum casing certainly draws your attention. It looks really good. Looks can be deceiving, but it this case, it's not! ;-)

I have used Harley Benton Powerplant power-supplies before...

I used the Powerplant Junior before, also for gigging. NEVER problems. No noise, no hissing, no buzzing..100% silent. No issues at all in 9 YEARS..
That is how good it is.

I wanted to replace it because the powercable is not easility replaceable.. if during a gig the cable has a problem, then you are scr*wed.

I replaced it with the Powerplant ISO-3AC SAG, which has a detachable cable.

The 12V LINK can be used for pedals / preamps too. No noise or other issues with my 650mA preamp.

If you are gigging quite a lot like me, 1-4 times a month, i advice to use the Harley Benton Power Supplies with the detachable cable. Do not use versions that have the 12v wall adapter,, if you want reliablitiy, use the versions that have the replaceable cables.

The price is crazy cheap compared to other decent noiseless power-supplies.. Many 150-300+ power supplies have less isolation/noise preventing measures.. And they are more expensive!!

Besides that, the brushed aluminum casings of the "Harley Benton Power-Plant ISO series" alone should be enough to buy one, quality craftmanship, it's beautiful.

Thank you Harley Benton.

Fine little power supply. I'm using the voltage adjustment to run my Warm Audio Foxy Tone Box fuzz at around 7 volts with good results. It gives me more defined but still gutsy tones and a bit more headroom before individual notes drown in fuzz mayhem.

The only small thing I can criticize is that one of the 4-9V outputs seem to max out just shy of 9V on my sample (I measured around 8.8V) but that's close enough to not make any noticeable difference in use.

Keep in mind that this has a 12V output and two 6-18V outputs that you should be a bit careful with before hooking it up to something rated for 9V. The markings are not super easy to read and I would recommend checking the voltages with a multimeter before connecting your pedals since too much voltage could potentially harm some equipment.

So, after many gigs of fighting with chunky power adapters for my LD Systems IEM and Wireless Instrument, along with my bass amp (all together in a 4u rack) I was sick of detangling all those whilst the guitar player was already out of the door.

This device has worked great. I can alter the voltage for the rack equipment and with a couple of polarity-reverse cables, it's all done and plumbed in permanently in a 4u shallow rack with my bass head.

It's actually fantastic as I can also power my Bass Fly Rig, which I only use for tuner and compression so I don't need it by my feet. I plonk it on top of the rack and power lead from this can reach it. My whole set up is now one plug, that splits for bass head and then all the rack gear from this powerplant. Don't think there was any documentation of people using it like this but it works so well! I'm now back to curling up a single long lead and being out of the wedding gigs before I realise I hate people.

Was searching for a reliable and noise free unit (under a tight budget) to power my pedal board, which consists of a hotone mp100 (18V @ 500mA), OBNE MAW xlr (9V @ 210mA), sennheiser xsw (12V @ 300mA) - everything plugged in works perfectly. The only problem was the hotone, which requires i think about 1.2A at the initial startup, so the adjustable outlets didn’t work with it. That’s where the additional 4A outlet on this powerplant comes in handy - rigged up a conector that goes from there to the original ampero power adaptor - success. The powerplant is also built like a tank, and looks very aesthetic. Used it in many rehersals and live gigs, so far no problems. I’d say i’m not going to need another power source ever again after this, very versatile.
