The voltmeter basic performance parameters are as follows:
Opening size: 45.5mm * 26.5mm
Dimensions: 48mm * 29mm * 21mm
Range: DC0-200V
Display: three 0.56 LED digital tube
Display color: green-red
Refresh rate: about 500ms / times
Accuracy: 0.5% (+/- 2 words)
Supply voltage: DC4.5-30V (independent power supply) with reverse polarity protection
Wiring instructions:
Red line: positive power supply, we need access to power within the positive range DC 4.5-30V
Black: negative public, both the negative power supply is measured with reference to the negative
Yellow line: positive measuring signal input
Description: Header requires a separate power supply, power supply range DC 4.5-30V, when access to the power supply line between the red and black,
Header will show 0.0, then you can access the yellow line and the black line between the measured voltage and the measured voltage range DC 0-200V
