MP710086 change input voltage from 110V to 240V

rsjawale24

As the title suggests, I need to change the input AC voltage of Multicomp Pro MP710086 bench top power supply from 110V to 240V AC.

I received this power supply as one of the prizes in the Hackster holidays giveaway but they sent me a model with 110V AC operating supply. 

I tried taking a look at the back panel and there doesn't seem to be a voltage change switch. Is there any switch inside the supply? Or any other way to change the input voltage?

I cannot use it as the supply in my country is 240V AC.

Pictures for reference below.

    You may need to open it up and see if there's any way to rewire it, but it's risky since there's no information on how to do this. Personally, I would rather return it, or request them to send another, since it will cost a lot to return.

    You could use a step-down transformer, but keep an eye on it, and always unplug from mains after use, because some of the low-cost ones run hot, and you don't want that to become a fire hazard.

    Thanks, I opened it up but there is no voltage change switch or anything mentioned inside. I'm guessing, they have specifically designed it (the transformer inside) for 110V AC. Unfortunately, this was a grand prize winning of over 5000 USD and most of the items they shipped are rated for 110V. 

    This power supply,  MULTICOMP PRO Rework Station (MP740131) and MULTICOMP PRO Soldering Fume Extractor (MP740146)
    all arrived with 110V AC rating. 

    So far, the best possible solution for me would be to contact Hackster and ask what can be done. I don't think test many prizes can be replaced Disappointed
    Or will have to buy a voltage converter.
