Help deciphering a Laserworld power supply specs

[HankLloydRight]

Hi Folks!

I'm taking the Laserworld RGB-PRO700 projector I got from Francis at FLEM, and planning to put larger analog diodes into it.

I need to figure out if the on-board 12V power supply is enough amperage. Adam says I'll need 3-4 amps to drive the green NDG700 700mW 520nm Diode as well as the 900mw 445nm (dr.lava build with flexdrive v3) blue diode I got from Laserguy.

I also have a 700mw 445nm (also from Laserguy) that seems to run fine on 12v, although I'm told red diodes need 5v and not 12v?

So here's what's inside the projector now -- see images below. I've photographed all markings on the device -- no 12V output rating at all. I'm not sure how to test it's maximum output and if it's enough to drive the above diodes.

Or should I just toss it and get a 12v PS with enough power?

thanks.

Followup: Projector seems to be running fine with stock PS, new 900mw blue, new 700mw red, and the stock TTL DPSS green.

I'm waiting for my 700mw green diode to arrive, hopefully it will still work with the stock PS.

Looking at the zfx-30 D01 type no.
It's most likely a 30 Watt supply, which makes it 2,5A @ 12V

5V is prefered for red drivers, 12V will work but will generate more heat.

I don't know what that Laserworld power supply is rated for, but I wouldn't take a chance. I'd just replace it (or worst case, pick up a cheap one and run them in parallel). Both the new direct-diode green and the direct diode blue will need to be run off 12 volts, and your total current draw will probably be something like 2.5 amps, if not a bit more. Then you've got a couple fans to run... So yeah, figure on a minimum of 3 amps.

The red driver *can* be run off 12 volts, but it really should be run off the 5 volt supply. As bart mentioned, it will run much cooler (the driver, that is). You already have a large 5 volt PSU in that case (it's powering the DPSS green), so you can re-use it to run the red driver.
