| 694787 | 2008-08-04 02:31:00 | Hi, I have got a few US items here that I need to supply power to. I know that I need a stepdown transformer but what do all the other numbers mean? Like 50VA or 120W??? I have a US power strip that I can plug into the transformer and then plug other items into that as they have US plugs on them. There is only one item that needs a direct feed of 120VAC and all the others have a 12VDC adapter for them. I could just change the plug on these to a NZ plug but not all of them can take 110-240VAC so rather just leave them all as is. |

| 694790 | 2008-08-04 15:02:00 | If you add all the W and/or VA values, that will give the total value that your step-down transformer should be. When you price the step-down transformer you may need to step-back for a while until your head stops spinning. There are two common types of step down transformer. Auto transformers are cheaper, but if you wish to gain the benefits of any no-claim bonus on your (or other family member's) life insurance, the isolated secondary type is better value. |
