Electrochromic film / Switchable glass ¯\_(ツ)_/¯

I’m trying to power PDLC Electrochromic film / Switchable glass from 12vdc . The film runs on 60vac.

Is there a neater/smaller way of powering this than having a 12vdc to 240vac inverter with the supplied transformer stepping it down to 60vac?

apparently the film works between 30-400hz and 60-75vac

It’s for a 12vdc car installation.

Any help would be much appreciated

Hi Charlie,

Have a look at our EL inverters and see if any of them might be suitable. From a quick look, it seems that EL panels operate on a similar principle to your film. Here’s some more info on how EL inverters work. I have never personally used electrochromic glass before, so I’m not sure if this will work, but at least it’s a starting point.

Putting this in a car is a very interesting concept, I’d love to see how you get on with it!

Hi Charlie,

A transformer which transit 12vdc to 60vac should be applied for your application.

PDLC film don’t work with 12vdc. So you need use this device to help the film work.

Hope it will help you.
