1.Introduction:
It is a DC-DC step-down module adjustable regulated power supply module with voltmeter display 10A high power 300W.

2.Feature:
1>.On-board voltmeter
2>.Display the status indicator
3>.High power adjustable voltage.
4>.With aluminum shell.

3.Parameter:
1>.Input voltage: DC3.5-30V
2>.Output voltage: DC0.8-29V
3>.Conversion efficiency: 92%
4>.Output Current: 10A(MAX)
5>.Digital tube display: Blue
6>.Digital tube quiescent current: 2-8mA
7>.Work Temperature:-20℃~85℃
8>.Work Humidity:0%~95%RH
9>.Size:85mm*58mm*33mm

4.Note:
1>.The voltmeter can be turned off, press and hold the switch for more than 1 second and less than 4 seconds, let go and turn it off, the voltage shows that the factory has been calibrated, no need to calibrate.
2>.It can display the input voltage/output voltage, short press the button below the digital tube to switch, the LED light of the standard IN measures the input voltage, and the LED light of the table OUT measures the output voltage.
3>.This is a step-down board, which requires the input voltage to be more than 1V higher than the output voltage.
