DC 100V 10A Voltmeter Ammeter

Working voltage:4.5-30V DC Note: The maximum input voltage can not exceed 30V, otherwise Module fails. Working current:≤20mA Display: 0.28" Two color blue and red Measuring range: DC 0-100V 0-10A Minimum resolution (V): 0.1V Refresh rate: ≥100mS / times Measure accuracy: 1% (± 1 digit) Minimum resolution (A): 0.01A Operating temperature: -15 to 70° c size :48×29×21 mm The connection below 10A does not need to connect the shunt.
