{"title":"LED Current Meter 50A (Green)","handle":"led-current-meter-50a-green","url":"/products/led-current-meter-50a-green","description":"This panel-mount LED current meter displays DC current readings from 0 to 50A on a bright green 3-digit LED display. It features reverse connection protection to prevent damage, and requires just four wires to install — no additional circuitry or components needed.\n\nWith a 4–30V DC power supply range and 2% accuracy, it's a practical solution for monitoring current in robotics, power supplies, battery systems, and other DC circuits.\n\nSpecifications\n\n\nMeasurement Range – 0–50A DC\n\nPower Supply Voltage – 4–30V DC\n\nDisplay – 3-digit 0.56\" green LED\n\nAccuracy – 2%\n\nPanel Cutout – 45.5 × 26.5 mm (1.79 × 1.04 in)\n\nOverall Dimensions – 48 × 29 × 21 mm (1.89 × 1.14 × 0.83 in)\n\n\nKey Features\n\n\nReverse Connection Protection – Prevents damage from incorrect wiring\n\nSimple 4-Wire Installation – No extra circuitry required\n\nPanel Mount Design – Standard cutout for easy enclosure integration\n\nIncludes Shunt Resistor – External shunt for high-current measurement\n\n\nIdeal For\n\nRobotics and motor current monitoring\nPower supply and battery systems\nSolar and charging circuits\nBench power supply builds\n\n\nPackage Contents\n\n1× LED Current Meter 50A (Green)\n1× Shunt Resistor\n\n\nResources\n\nWiki Documentation\n\n\n\nWarning: The power supply and measurement terminals share a common ground. The measurement terminal must be connected in series after the load on the ground side. Do NOT connect the measurement terminal to the positive side — this will permanently damage the meter.\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":10814,"title":"Default Title","sku":"DF-DFR0245-G","price":12.68,"on_sale":false,"in_stock":true,"available_quantity":52,"option1":"Default Title"}]}
