Adjustable Potentiometer Design LED Digital 2line Voltmeter Red Blue Green

Features: *Use our digital voltage gauge to accurately measure voltage, 2-line design, which is convenient for wiring and reverse connection protection. *No external power supply -use measurement voltage as a power supply. Measurement range: DC4.5V-30V. *Bright and clear LED display panel for easy reading. The automatic movement display is convenient. *When there are a small amount of errors, the potentiometer on the circuit board is calibrated. *High measurement accuracy, good stability, and convenient installation. Meet most application requirements. *Low starting working voltage, red is as low as 4.5V, green is as low as 4.7V, blue is as low as 5.0V

Specification: Model: DSN-DVML-568-2 Measurement range: Red DC4.50-30.0V, Green DC4.70-30.0V, Blue DC5.00-30.0V Power supply scope: No need to supply a power supply, directly use the test voltage as the power supply, the range is the same as above Maximum input: DC30.0V. Note: Input voltage higher than 30V may be permanently damaged Allow error: ±1%; when greater than or equal to 10V, the error is ±0.3V; when less than 10V, the error is ±0.10 Input impedance:> 100KΩ Work current: red
