Why doesn't the current limiting function work?

Why doesn't the current limiting function work?

Post by himmelsteht » Thu Mar 01, 2018 7:04 am

Is there a fix?

12VDC max 1.5A power suppy connected, 8.2 Ohm load. I have the current limiter set to 0.6A.

Draws 1.15A at full PWM, which seems to indicate the current is being limited to 1.2A (this load would otherwise draw 1.45A).

This is not ideal as I am driving an expensive peltier at max 0.8A, and would like that 0.6A current limit to work.

Any ideas?

Cheers
