Description

Introducing the 0.28-inch Digital Voltmeter Ammeter DC 100V 50A, a compact yet powerful dual-display voltage and current monitoring solution for DC circuits. This meter is specially designed for DC power systems, battery packs, DIY power banks, solar projects, EV monitoring, and power tool testing, offering accurate and simultaneous display of voltage and current.

The device supports up to 100V DC voltage and up to 50A current (with included precision shunt), making it suitable for a wide range of electrical monitoring applications. The 0.28-inch red and blue LED display ensures clear visibility even in low-light environments. It includes a separate power supply input (630V DC) to avoid distortion in current readings, especially in high-power setups.

It comes with two harnesses:

• A 2-wire harness (RED & BLACK) to power the meter independently

• A 3-wire harness for voltage and current sensing, connecting directly to the load or battery system

Note: If your input voltage is above 5V, a buck converter is recommended for protection and accuracy. Avoid using the same power source for both meter and load to prevent reading errors.
