    FlexMod P3 problems

    I did. I'm supplying V+ with 9V. I am able to adjust the zero bias to the output that I desire, however, when I add any voltage to the M+ signal, the fault LED blinks after 7 seconds and then after another 7 seconds, it stays on and the driver does not give out any current. We are measuring...

    FlexMod P3 problems

    Thanks for the reply. The DMM is measuring at the 500mA range. We shouldn't have an output of over 500mA. I think there is something wrong with the driver. When I set the M+ to GND, there are no issues and it runs at the preset 0Bias setting. However, when I connect it to the modulation...

    FlexMod P3 problems

    Since I'm just testing it for now, I'm using an old M140 diode that is burned out (hardly puts out 30mW). Ultimately I want it to power a S60J diode at 450mA max. The power supply I'm using now is just a DC power supply at 5V and the driver has the heat sink that came with it. I figured it...

    FlexMod P3 problems

    Hey all I'm using a Flexmod p3 driver to provide current to my laser diode but I cannot get it to even provide any output. There was only one instance where I was able to set the 0Bias and Gain where it worked perfectly and could be driven by a PWM signal afterward. However, the next day...
