Describe:
Ultra-low cost, high precision meets most application requirements.
High precision
Low start working voltage, red low 4.5V, green low 4.7V, blue low 5.0V.
With reverse connection protection, it will not burn 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
High input: DC30.0V. Note: Input voltage higher than 30V may be 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
Input impedance:> 100K ohm
Working current: red <23mA, green <18mA, blue <13mA
Refresh speed: about 300mS-time
Display mode: three-digit 0.36"L ED digital tube
Lead length: 15cm
Mounting hole: hole distance: 28mm, aperture: 2.8mm
Working temperature: -10C~65C
packing list:
1*digital voltmeter
