Using a 16VDC power supply with a PWM charge controller

Re: Using a 16VDC power supply with a PWM charge controller The big problem is that a PWM controller does nothing to regulate the peak current drawn from the source. If the source is a PV array, that current will be limited by the available sunlight and no damage will occur.

Testing MPP Charge controller function with bench power supply?

I would not connect a regulated DC supply to an MPPT charge controller. MPPT charge controller are sophisticated devices that modify their apparent load to the supply (in this case a regulated supply) in order to identify the maximum point of the supply (in this case there isn''t one - maximum power is delivered on all loads, hence regulated).
