About this product
The B3606 is a non-isolated buck DC-DC converter module with a digital display and adjustable output from 0 to 36 V at up to 6 A. It accepts a 6 to 40 V DC input and includes short-circuit protection. It is suitable for stepping down battery or DC supply voltages for bench use and for powering projects with adjustable voltage.

Frequently asked questions
Can this module step up voltage as well as step down?
No. It is a buck (step-down) converter, so the output must stay below the input voltage. Keep the input at least a little above the set output voltage to maintain regulation.
How do I wire the input and output terminals?
Connect the positive and negative supply to the input terminals, observing the polarity marked on the board, and take the regulated output from the output terminals. Set the output voltage with the digital controls before connecting a load, and make sure the load current stays within 6 A.
