AUTOMATIC STEP DOWN - STEP UP MODULE 2A IN 5-30V OUT 0.5-30V

Used as a general step-up and step-down module with overcurrent protection capability

Instructions:

(1) Adjust the CV constant voltage potentiometer so that the output voltage reaches the value you want.

(2) with the multimeter 10A current measurement output short-circuit current (directly to the two test leads can be connected to the output), while adjusting the CC constant current potentiometer so that the output current to achieve a predetermined over-current protection value. (Such as multimeter shows the current value is 2A, then you use the module when the maximum current can only be 2A, the current to 2A when the red constant voltage constant current indicator light, otherwise the indicator light off)

Note: When used in this state, because the output has 0.05 ohm current sampling resistor, connected to the load will be 0 ~ 0.3V voltage drop, this is a normal phenomenon! This voltage drop is not pulled down by your load, but is reduced to the sampling resistor.
