0.28 inch Digital Voltmeter Ammeter DC 100V 50A LED Amp Volt Meter With Shunt
[Ammeter and Voltmeter] The 0.28 Inch Digital DC Voltmeter Ammeter 100V 50A with Shunt is a compact and high-accuracy dual LED panel meter designed to measure DC voltage and current simultaneously on a single display. With a measurement range of up to 100V DC and 50A, this meter is ideal for monitoring battery systems, power supplies, solar setups, chargers, and DIY electronics projects. This panel meter features a bright dual LED display that clearly shows voltage and current values at the same time, making real-time monitoring easy and convenient. Its small size and lightweight design allow easy installation in panels, enclosures, and control boxes. The module comes with two wiring harnesses — one for powering the meter (red and black pair) and another for measurement and shunt connection. The meter operates from an independent 5V power supply (recommended) for best accuracy. While it can be powered from 6–30V DC, using the same supply as the measured source may slightly affect current readings. A 50A external shunt is included for accurate current measurement. Different wiring variants may be shipped, but functionality remains the same. This meter is an excellent choice for battery packs, solar systems, DC power supplies, electric vehicles, inverters, and lab projects. ⭐ KEY FEATURES ✔ Measures DC Voltage up to 100V✔ Measures DC Current up to 50A (with included shunt)✔ Dual LED Display – Shows volts & amps simultaneously✔ 0.28 Inch Compact Panel Size✔ High resolution 0.1V measurement✔ Small, lightweight & easy to install✔ Separate power input harness for stable readings✔ Ideal for battery & DC system monitoring✔ Brand new, high-quality module 🔧 TECHNICAL SPECIFICATIONS Display Size: 0.28 inch LED Voltage Measurement Range: 0 – 100V DC Current Measurement Range: 0 – 50A DC Voltage Resolution: 0.1V Meter Power Supply: 5V DC (recommended) Supply Range: 6V – 30V DC (separate supply preferred) Display Type: Dual LED (Volt + Amp) Shunt: External 50A shunt included Mounting Type: Panel mount Wiring: Dual harness (power + measurement) ⚠️ IMPORTANT NOTES Use a separate 5V supply for best accuracy If input voltage is above 5V, use a buck converter Wiring color/order variants may differ but function is same Incorrect wiring can damage the module 🎯 APPLICATIONS Battery monitoring systems Solar power setups DC power supplies EV & e-bike systems Inverter projects DIY electronics labs Charging stations 📦 PACKAGE INCLUDES 1 × 0.28″ Dual LED DC Volt Ammeter Panel Meter 1 × 50A Current Shunt
LM358P PDIP-8 High Gain Operational Amplifier
[Logic Gates IC] Description These devices consist of two independent, high-gain, frequency-compensated operational amplifiers designed to operate from a single supply over a wide range of voltages. Operation from split supplies also is possible if the difference between the two supplies is 3 V to 32 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. The low supply-current drain is independent of the magnitude of the supply voltage. Note: Product may vary from images shown in terms of brand name according to the availability. Package Includes: 1 x LM358P PDIP-8 High Gain Operational Amplifier
