LED Dial Direct Power Supply 4.5~30.0V Voltage Panel Meter Accurate Measurement With Re Connection Protection

Points:1、Voltage Measure: This dial voltage meter can measure voltage between DC 3.5 to 30V.2、Accurate Measurement: The dial ’s measurement accuracy is 0.01V (3-10V); 0.1V (10-30V).3、LED Display: There are three dial LED tubes in the dial .4、Re Connection Protection: With re connection protection, this dial will not if connected rely.5、Direct Power Supply: No additional power supply is required. The measured voltage is directly d as the power supply.Features:1.Low-start working voltage, red 4.5V, green 4.7V, blue 5.0V.2.With re connection protection, it will not  if connected rely.3.Power supply range: no need for additional power supply, it directly  the measured voltage as the power supply, so the range is the same as above.4.Tolerance 1% 0.3; error is greater than or equal to 10v±0.10v; error is le than 10v ±.5.Update speed for once is about 300ms.6.Three-way led dial tube display mode.Specification:Model: DSN-DVML-568-2Input impedance:> 100K Working current: red
