Ultra-low cost and high precision meet most application requirements.
● High precision
● Low start working voltage, Red 4.5V, Green 4.7V, Blue 5.0V.
● With reverse connection protection, it will not burn when connected in reverse.

Technical Parameter:
Measuring range :Red DC4.50-30.0V, Green DC4.70-30.0V, Blue DC5.00-30.0V
