LED Current Meter 50A is a compact DC current measurement module designed for real‑time monitoring in power electronics, robotics systems, and embedded projects. This panel‑mount digital ammeter measures currents from 0–50A with approximately 2% accuracy and uses an external shunt to maintain measurement stability under higher loads. A 3‑digit LED display provides clear numerical feedback for quick diagnostics during circuit testing or equipment operation. Built‑in reverse connection protection improves reliability during installation, making this current monitoring module suitable for experimental circuits, robot platforms, and general electronic instrumentation.
Note: The product has two kinds of chips (STM8S003F3P6 and STM8S003F3U6-QFN) and will be randomly selected for shipment.
Reverse Connection Protection for Safer Installation
This digital current monitoring module integrates reverse polarity protection to reduce the risk of damage caused by incorrect wiring. Such protection is especially valuable in prototype circuits, laboratory testing environments, and robotics development where wiring changes occur frequently. By preventing burn‑out during accidental polarity reversal, the panel current meter increases operational safety and helps maintain measurement stability in demanding electronics setups.
Direct Current Measurement with External Shunt
A precision shunt resistor enables measurement of DC current from 0–50A while keeping the display electronics protected from high current loads. This high‑current sensing approach ensures accurate readings with approximately 2% error across the measurement range. The design allows straightforward integration into power circuits, battery systems, and motor control setups where reliable monitoring of current consumption is required.
Clear Dual‑Color LED Display
A 3‑digit 0.56‑inch LED digital tube delivers clear current readings even in dim or cluttered environments. Available display colors include green or red, allowing flexible visual integration with different equipment panels or instrument enclosures. The bright numeric display improves readability during troubleshooting, system monitoring, or equipment calibration tasks.
This panel digital ammeter is well suited for circuit debugging, robotics projects, power supply monitoring, and laboratory electronics setups. Reliable high‑current sensing combined with simple four‑wire installation makes this current measurement device practical for hobby electronics, educational laboratories, and equipment panels requiring quick visual feedback of DC current levels.
