Default Flexmod P3. Please help

Hi,

I bought 2 new Flexmod P3 drivers for the purpose of building another 2 watt+ 445nm laser system using a PBS.

When I drive a single diode if works perfectly. I can use the modulation with my software or simply using a 3v battery...

When I put two diodes in series it works fine until I try modulate it. The diodes turn off and a little red led lights up on the driver.. This happens whether I use a battery or ILDA software for modulation.

Don't know why??

Default Re: Flexmod P3. Please help

Well. just in case anyone was wondering there is a solution. 12V regulated power was not enough voltage to drive both diodes in series. I used 18V and it worked perfectly
