Step Down With LED Voltmeter, LM2596S, 4-40v, out 1.25-37V
Non-returnable
BD 8.500
LED digital voltmeter tube, the accuracy is adjustable. Can be aimed at your multimeter adjustable accurate.
Updated Version: with reverse voltage protection, over-temperature and short-circuit protection, thus making it much safer to use.
Input:DC 4V to 40V ( input voltage should be 1.5V higher than the output voltage). Output: DC 1.25V to 37V voltage is continuously adjustable.
High conversion efficiency, simple regulating operation, rotate the top screw of potentiometer clockwise to boost, anti clockwise to reduce voltage.
This module can be applied to fields in the input voltage is higher than the step-down output voltage, such as batteries, power transformers, DIY adjustable power supply, 24V Car T of the power equipment industry buck, 12V switch 3.3V, 12V switch 5V, 24V switch 5V, 24V switch 12V, 36V 24V turn and so on.

ON BOARD VOLTMETER:
- Use on board switch to change display measurement between the input or output voltage, and a LED indicate which value(IN/OUT) is being measured. This setting is stored even after power off.
- Voltmeter can be turned off, just keep the switch pressed for 1 second and leave it.
- Adjust Input and output voltage measurement error offset - long press switch for 4 seconds or more, the digital display flashes, then short press the button to change the value of output (values range from -0.5 to 0.5, the unit is V), a positive number indicates an upward calibration, negative downward calibration. Now press the button again for adjust input offset in same manner.
