Description
DC 4.5v-30V 0-50A Dual LED Digital Voltmeter Ammeter Voltage AMP Power Meter
(connect with 50A/75mV shunt) Does not include)
Product Features:
1.The small size of the two-color dual instrument.Voltage and current can be displayed on the same screen at the same time
2.This instrument test voltage, current, power supply is taken from the test loop.No additional power supply
3.The the instrument test voltage supply range: DC4.5 ~ 30V,The reverse does not burn,
Note: The maximum input voltage can not exceed 30V, otherwise there is the danger of burned
4.The instrument is equipped with five wiring.Convenient access to car /
battery car / motorcycle car line,,Used to monitor the battery
voltage,,Grasp the battery voltage state,can also be used for other
products, the use of Voltage/current measurement.
Wiring Method:
The instrument with five lines:
Thin black line: Header supply ground
The Thin Red Line: Header powered regular (Note, thin red and black line between the voltage can not exceed 30V)
Thick black lines: public test end
Thick red line: measuring the positive voltage input terminal
Yellow lines: current input terminal; header uses of design, the
measuring end of the ground and the ground of the power supply side is
the same, it is only then measured the back of the device, as shown in
the following figure, the wrong will burn (such as single voltmeter, it
is recommended that the yellow line with black lines together, to
prevent outside interference cause ammeter digital flashing)Technical
parameters:
0.Supply voltage: 4.5 30V (wide range)
1.Test voltage: 0 ~ 100V; minimum resolution: 0.1V
2.Test current range: 50A resolution: 0.1A (requires an external shunt)(connect with 50A/75mV shunt) Does not include)
3.Operating Current: <60mA
4.Display: 0.28 "LED, two-color (red and blue) colors
5.Dimensions: 48 × 29 × 21 mm
6.Mounting cutout: 45.5 × 26.5 mm
7.Measurement rate: ≥ 500mS / times
8.Measurement accuracy: 1% (± 1 words)
9.Extreme working conditions:
9.1.The minimum Operating voltage: +4.5 V
9.2.Maximum working voltage: +30 V
9.3.Operating temperature: -10 to +65
9.4.Operating Humidity: 10 to 80% (non-condensing)
9.5.Working pressure: 80 ~ 106kPa
9.6.Sun exposure: no direct exposure
Note: The meter needs to connect with a 50A/75mV shunt.
If not, the current can not be displayed properly.
If to connect with other ranges' shunt, the current can not be displayed properly, either.
Whether or not connect with a shunt, voltage can be displayed properly.
