●High precision
●Low starting voltage, minimum 4.5V for red, 4.7V for green, and 5.0V for blue.
●With reverse connection protection, no burning if connected reversely.
Technical parameter:
Measuring range: red DC4.50-30.0V, green DC4.70-30.0V, blue DC5.00-30.0V
Power supply range: No need for additional power supply, directly use the measured voltage as the power supply, the range is the same as above
The highest input: DC30.0V. Note: The input voltage higher than 30V may be permanently damaged!
Allowable error: ±1%; when greater than or equal to 10V, the error is ±0.3V; when less than 10V, the error is ±0.10
