Silicone Bed Heater

[Gort]

Hi all, I've just bought a 20x20 Silicone heater trying to solve the heating issue of rapide lite printer.

What's your opinion about the best method to install into the bed?

I'd glue the silicone heater to a brand new 20x20 alu plate with th e same specs as the rapide one (but without the heating part of course) and add a glass on top of it.

Then power it using a relay from the 125/220v line.

But its a 12v heater not high voltage its low dc current

Did you check the amps required to heat it up prior ordering it?

[Gort]

well no, its not on the specs
I bought it from E3D

What about the Watts?

[Gort]

I thinks it's 10 Amps, on the specs it tells 1.1 Ohm internal resistence so:

I = V / R
I = 12 /1.1

So its a 120 Watt - 10 amps heater

Any idea where I can get a new alumium plate? I would like to use a new one instead of the original

[update]

well the silicone heater its a way better it's really fast but the problem I've found it's the mosfet gets really hot and after 1 min of heating it shut off, I Think I'll need a SSR DC-DC

Thats the issue, too much wattage required from your board....
