Is there anyonve can help me to convert my recently bought light controllers from 120VAC to 240VAC. Unfortunately i have a big mistake when i bought it Online and forgot to request to convert it to 240VAC.

From the manual:

For 240 VAC operation, only one jumper on the center two pins of this header must be installed –

AND – the ghost loads must either not be present or of the correct value. Boards configured for 240VAC operation will be marked with a sticker specifying 240VAC operation allowed.

i am stuck with the ghost loads i don't know how to remove it atleast... :(, i am from Sydney Australia and to ship it to the factory will miss my light show display on Christmas.

If your board doesn't have the sticker saying it is capable of 240VAC, then it simply will not operate at 240VAC.

And yes, this is a change from the pre-G3 controllers. Unfortunately, there is more to 240VAC than changing a jumper on the G3 controllers.

Any other solution, is an electrician can help?

Unless you are going to covert your 240 down to 120, I don't think an electrician can help.

There is something, I forget exactly what, that is different on the new G3 boards for 240V. This would be a component on the board that would need to be replaced.

The circuit board said ctb16pcg2 - v4, do it make any difference

That is a "G3" controller. There was a silk screen error that caused the new controllers to have "G2" on the controllers.

Hi don, i read the enthusias manual to build the controller board, the difference is the resistors installed for 120 vac and 240vac (R7-R14, R20-R27). If I replace the resistor from the board do you think it will work?...

I'm just desperate to make it work i invested a lot for my Christmas lights and outdoor decoration and I don't want my Loraine controller waisted. I bought it online middle of this year no option for me to select 240vac setup :( so I forgot to mentioned it in my order. Big mistake on my part :(

Edwin, that sounds like it would work. However, I'm not a DIY expert by any stretch of the imagination. I have no idea what resistor goes where.

So, take what I'm saying with a grain of salt. I think it would work, but I could be wrong.
