This power supply replaces one for a 32 inch fiber optic Christmas tree that belonged to my mother. When I unpacked the box this year, the old power supply fell out and broke. The new one is a perfect replacement, and I was pleased by the quick delivery. Thanks very much!
Appreciate the review Louie. So happy the correct power supply and plug size was a perfect match for your lights.
Arrived on time, I wish it worked because it cost me more to have it shipped then the cost for the Power Supply. Not a happy customer

I purchased this for my fiber optic Hummingbird lamp because it has a color wheel synchrous motor in which requires the above power adapter. This company is the only company I found that carries these adapters. I bought one, and now have bought 2 more, one for my sister who has the same lamp and another for me, because I recently purchased another fiber optic lamp. Hans was very helpful and I truly appreciate the help he provided. Thank you Hans!
Thank you for your kind words Marcia. I hope the 2 additional power supply with the modified plug works well with your wonderful lamps.
I bought this adapter for my Boss SE-50 since I did not want to spend $40+ on a giant brick known as the BRB-120. I had one of the original Roland power supplies back in the day and hated how much space it took up just for a half-1U rackmount. However the plug on the AC/AC adapter I bought here is 2.1mm x 5.5mm so I also got a converter on this website to adapt it to the 3.0mm x 6.3mm plug in the back of the SE-50. I have confirmed this to be operational, and a less expensive shoehorn for the BRB-120.

Good quality item. Good price. It came quickly. I expected these to be more expensive. There was no reason to make do without one for so long. Thanks guys.
This unit was a replacement for the transformer in my HVAC furnace. It delivers the required current and works properly. My system is back in service
AC-AC Power Supply 18V AC @ 3500mA; DC plug 1.35 x 3.5mm
I love it thank you very fast shipping also
This is a true technician's isolation transformer that does not carry the ground or the neutral through from the source. This is a crucial difference from most other isolation transformers on the market. It's a joy to have the flexibility to safely establish an arbitrary local ground reference anywhere in an active circuit for *one* oscilloscope probe (note that additional probes must use that same ground reference point to avoid the risk of a short circuit and personal injury or damage to the oscilloscope or the UUT). This product uses a toroidal transformer that is quiet, efficient and powerful. I'm pleased with the isolation transformer, the customer service and the shipping department who expertly and carefully packaged this heavy unit to prevent damage in transit.
Works great. Just a little concerned that the cord is a little flimsy so I added a 4ft heavier extension cord. Hope that’s OK
Excellent! Works perfectly! Thank you!

Shipped fast and sent the correct product.
Variable Transformer 10 Amp (1000 Watts); 0~130VAC Output w/ISOLATION
Sadly the 1.5V DC always gives me 3.5V output. 12VDC always gives around 20V output.
Hello Ning Yu,
Sorry the power supply wasn't what you were expecting. Please understand this is a AC-DC 'non-regulated' power supply. Therefore, a no load reading on a non-regulated supply typically is 1.5x higher. The voltage would drop to the intended setting once there is a load on it.
You would need a 'regulated' or a switching power supply which are always regulated. Our PHC-1000k and PHC-2200W models are regulated and would read about 0.2VDC higher on a no load meter reading. Hope that helps.
Regards,
Hans
