Dual Led 0.28 ” Display for DC0-100V Voltage and Current Digital Meter Red and Black 0-50A with Shunt

Description

This is 0.28-inch Digital Voltmeter Ammeter DC 100V 50A LED Amp Volt Meter With Shunt. This meter will measure up to 100 VDC with a 0.1-volt resolution.
One thing to note is, this meter has 2 wiring harnesses. One harness is to provide power for the meters, that’s the 2 poles with a RED and a BLACK lead. Small size, portable, the magnitudes of voltage and current are displayed on the same screen at the same time.
This can be supplied anywhere from 6 volts DC up to 30 VDC. This is a separate power supply that is isolated from the source, it is possible to use the same supply but it seems to affect the amp meter reading. The 3 wire harness is used for a ground that connects directly to the battery or supply ground of the load.

Application:
– Battery Voltage Monitoring: Effortlessly assess battery voltage levels (Li-ion, lead-acid, etc.) in real-time to prevent over-discharge or failure.
– Power Supply Testing: Monitor both voltage and current outputs in DC power supplies, adapters, or DIY power systems to ensure stable operation.
– DIY Electronics & IoT Projects: Integrate this module into projects (like Raspberry Pi systems, robotics, or automation setups) to display live power consumption without the need for programming a display.
– Automotive & Vehicle Applications: Ideal for use in cars, bikes, or electric vehicles to monitor battery health and charging system performance.
– Circuit Debugging & Troubleshooting: Facilitates the detection of faults by verifying whether voltage and current flow correctly in a circuit during testing and debugging.
– Embedded System Panels / Enclosures: Can be panel-mounted in control boxes, inverter systems, or laboratory setups to provide continuous real-time electrical readings.
