Hi everyone,
I am using USB-6009 in order to control the voltage across 5 identical LEDs in parallel through using labview which will be later on used for PID temperature control ( the connection can be changed to series if u suggest any other solutions). Each LED needs 30mA and 5V. The USB only provide a maximum voltage of 5V and 5mA. Is there any alternative NI control hardware that I can use instead of the USB-6009 that is more efficient for generating enough voltage and current for my application? Or if you know of any alternative circuit connection for fulfilling my application?
Thanks 🙂

Just use some op-amps in a voltage follower configuration.
