Great - thanks for this. It isn't obvious that you need to turn the tiny screw a lot before the output voltage changes. Thought mine must be DOA until I looked at your demo.

Mine looks the same as yours but to alter the output you press the right button until the output led lights then hold the right button for 2 secs let it go then use both buttons to hire or lower the out put voltage. you use the same method to calibrate if the input is wrong just press the right button the input led lights hold for 2 secs and adjust as necessary

IF THE "OUT "VOLTAGE DOES NOT WORKS (DO NOT CHANGE) THEN DO THIS:
TURN THE DIAL COUNTER-CLOCKWISE AT LAST 10 TIMES AND IT WILL START WORKING AGAIN !

i ve a battery in 36v 20ah, i ve a 12v dc 600w 52amp motor (for boat). the question is: if i use a step down power can i use this battery for have much ah? in theory 36x20 720ah. is correct?
thx for response.

[@samacochan]

Do you know you have to calibrate first ? What are you trying to tell ?
No explanation. weird.
