Peltier (TEC) from C@$!0 XJ-A1*0 projector

[WonHungLow]

trying to start a new project and am having trouble finding info on the TEC used in the projector.
searched and have seen people use them at 5V@12.5W (or 2.5A) but i dont know if this was accurate (title was "semi-ghetto peltier-cooled handheld lab device" ???

anyone happen to know the voltage and amperage (or watts) that this uses????

any help is appreciated...

I drive them with constant current up to 2A, I don't know the limits.

P.S. You may want to edit the company name out of the post and title, they have caused legal issues for the forum in the past.

2A at what Voltage? 5? 12?

I don't recall, and I can't find where my peltiers are, sorry.

The LM317 diode driver set to 2A will work for this if you've got the parts

ive got tons of 317's and a couple of lm338 to drive it ~5A but to drive it efficiently, im trying to find the Vf for the TEC so all the extra voltage going into the regulator wont be converted into alot of heat.
