Buy DROK® DC Digital Multimeter 0-100V Voltmeter 100A Ammeter 4 Digits Dual Display Panel Voltage Meter Testing The Current Volt Amp Monitor Test Gauge Car Multimeter with 100A Shunt

Description:

Power supply: DC 3.8-30V

Power consumption: <= 20mA
Refresh rate: about 3 times/s

Voltage range: 100V

Voltage internal resistance: 400K

Current range: 100A

Current internal resistance: 75mV shunt

Test accuracy: ± 0.2% + 2 words

Current resolution: when within 100A, 00.00-99.00; when 100A, 100.0.

Overload capacity: 120A, one minute

(when within the overload capacity, the display still can show but please don’t over the specified time. we suggest the average current be about half of the range)

Display color: red voltage + blue current

Hole size: 45.5mm * 26mm

Dimensions: 48mm * 29mm * 20mm

With reverse polarity protection, but the input still can’t over 30V when connecting reversely.

The meter can measure positive voltage and positive/negative current, the decimal point will flash when measuring negative current, and it will automatically move when less than 1A, unit is mA.

Current sampling uses an independent AD conversion chip, more stable and accurate. Very suitable for monitoring battery.

 

Note:

The meter must be powered by an isolated and not common ground power supply, or it will cause large errors when measuring current, and the best is DC 5V. You can also make an isolated power supply by an isolated module.

The meter should be connected to the negative to measure current, or it will be burnt.

 

Package Includes:

1 x Volt&Amp Meter

1 x 100A/75mV Shunt

• Can measure positive voltage and positive/negative current; the decimal point will flash when measuring negative current, and it will automatically move when less than 1A, unit is mA
• Current sampling uses an independent AD conversion chip, more stable and accurate, which is suitable for monitoring battery
• With reverse polarity protection, but the input still can’t over 30V when connecting reversely
• The control segment of this meter adopts CPU chip, so there are 20 pins which can make better performance
