Thanks

Hello Roberto,

Thank you for your purchase and taking the time to leave a review. Have a great day!

Very loud hum

Unfortunately, this transformer hums louder than the hum I'm trying to eliminate from my amplifier. It actually made me a little nervous to use so I'm getting rid of it. It was on sale though, so that was a plus.

Thanks for taking the time to leave a honest review. Please look out for our email to see if we can resolve this issue. The isolation transformer usually would not have a hum unless it is defective or it is running near or at the rated wattage.

A Workbench Essential

I use this to isolate my Powerstat and Dimbulb on my workbench when testing electronic gear. 300 VA is all I need because of the Dimbulb limiter and it works as advertised.

Thank you for your review! We're thrilled to hear that our 300VA Isolation Transformer has become an essential tool on your workbench. We're glad it's working as advertised and meeting your needs.

Better than expected

For the price point, this is a great deal! The order was well packaged and not damaged at all, unlike some other vendors that I have bought from. The transformer was not advertized as a toroid, but it is which is a big plus. It is properly mounted to the case with a good bolt, and isn't going anywhere. The case itself is decently thick sheet metal. Solder connections on the inside were good, wiring was tidy, and nothing needed rework. Input side had a two-pole switch and a glass fuse. Output has a switched breaker. All in all, this is a really nice and well built unit and you can't beat the price.

Thank you for taking the time to leave such a positive review of our 1000VA Isolation Transformer. We are delighted to hear that it exceeded your expectations in terms of quality and packaging. We take pride in providing well-built products at a great price. Our team works hard to ensure that every detail, from the toroid design to the sturdy case and clean wiring, meets our high standards. We appreciate your business and hope to continue exceeding your expectations in the future.

Great customer service & speedy delivery!

Located needed items in a Google serach but had two quick technical questions – I called and got a live person who referred me to technical sales who returned my call within the hour – questions answered, ordered and items shipped the same day and delivered the next. A great customer experience all the way – I’ll be back with any future PS needs!

Ben is my boss who authorized the purchase. I'm Derrick "Senior Maintenance" that chose and uses the power supply, and it is functioning nicely. In addition: the customer service was great. Thank you.

DC Barrel Plug Adapter to 2.5 x 5.5mm RIGHT ANGLE plug from 2.1 x 5.5mm
Serves a need very well

This connector allows one to adapt a DC power need to a slightly different size. I had a Line 6 foot switching pedal power plug I needed to match up with a Strymon power cord connected to the Strymon Zuma power supply. This allowed me to match them up without stripping fine wires and soldering them together. It's maddening why companies continue to use different male and female connectors and it creates hassles. It's the same with computer USB names and varieties. Standardization would be appreciated.
