3pcs 0.36 Inch DC0V-32V Red LED Digital Display Voltage Meter Voltmeter Reverse Connection Protection

Feature: ? Super high precision? Ultra-low startup voltage, red minimum 2.5V, green minimum 2.7V, blue minimum 3.0V. When the power supply voltage is lower than 3.5V, only the brightness is lowered, but the measurement accuracy is not affected. ? With reverse connection protection, it will not burn. Measuring range 0.00V - 32.0VP ower supply rangeRed DC 2.50 - 32.0V, green DC 2.70 - 32.0V, blue DC 3.00 - 30.0VH ighest inputDC 32.0V.
Note: If the input voltage is higher than 32V will damage. Allowable error 0.1 %, the decimal point is automatically shiftedMeasurement error is +/- 0.1V when measuring voltage >= 10.0VM easurement error is +/- 0.02V when measuring voltage <= 9.99VInput resistance> 100K ohmWorking currentRed < 23mA, green < 18mA, blue < 13mARefresh rateAbout 300mS onceDisplay methodThree 0.36" LED digital tubesDisplay colorredLead length15cmDimensions23 x 15 x 10 mm, (length X width x thickness) (without mounting ears)
