diymore 300w/500w 20A dc-dc converter buck step down constant current module led driver power step down voltage module electrolytic capacitor

 

 

Features:

 

With a wide input voltage range from 6v to 40v, the step-down converter can precisely adjust the output voltage and current.

 

Efficiency can be up to 96%, measured at 20a, converting 24v to 12v.

 

It is designed with 75v / 80a large double tube current mos.

 

High frequency low resistance electrolytic capacitor for input and output use, low ripple, stable output.

 

Wiring is convenient with these large current screw terminals 30a.

 

The buck module has 2 heatsinks that could increase heat dissipation.

 

When there is a big difference between the input and output voltage, please decrease the power and current.
