Digital Voltmeter and Ammeter for DC Voltage 100V/10A - EXDC10

Digital DC Voltmeter and Ammeter KWS - DC 121 is used for measuring DC voltage within the range of 4.5 - 100VDC. Below 4.5V the voltmeter does not work, above 100V - it will burn out. Reverse voltage protection is available. The device's power supply range is 4.5 - 30VDC. The power supply and measurement circuits are separate; please be careful when applying voltages!!! The device also measures DC current within the range of 0 - 10A. Idle consumption is approximately 20mA. Voltage is displayed on a 7-segment LED display, with a total of 3 digits per value. Installation is achieved by pressing into a hole with approximate dimensions of 46 x 27mm.

• Pin connections:

- Thin red wire: VCC, do not exceed 30VDC

- Thin yellow wire: VIN, measured voltage

- Thin black wire:GND, common ground

- Thick red wire: I+, positive current input

- Thick black wire: I-, negative current input

• Wiring diagrams:

• Advantages of the Digital DC Voltmeter and Ammeter

- Small module size allows for easy integration into devices

- Built-in shunt resistor in the module

- Reverse voltage protection

- Low current consumption

- Easy readability of readings         

• Applications of the Digital DC Voltmeter and Ammeter

- Applications in automotive and industry

- Monitoring and control of DC voltage and current

The device may measure only one of the two values!

The shunt resistor is built into the PCB!
