I need to convert an Itech 8000 from 120v to220v, please advice, thanks
It should work fine at 220V. Verify the rating next to the power inlet : 120V~220V! or is it 240V???
No mod! The ITech SMPS amp supply will accept AC voltages from 120 to 240V.
For example, just replace the 120V AC plug on the original power cable and add the correct 220V plug to your needs and connect to a 220V AC source!
Basically, just replace the original 120V power cable for your appropriate 220V version.
Yes, a bit confusing : connect the power cable hot wire to one of the plug's hot terminal and connect the cable cold wire to the other plug's hot terminal. Both commons are connected together.
You had 120V between hot and cold and now 220 between the two hots.
