FAQs

Can this module handle a 72V battery?

No, this module is not suitable for an unregulated 72V battery as the voltage can exceed the safe working range.

How do I adjust the voltage and current?

Use the VADJ knob to adjust output voltage and the IADJ knob to set the current limit—both turn clockwise to increase.

Is the fan always running?

The fan operates automatically based on load and temperature conditions to ensure efficient cooling.
