Saftronics Battery Monitor Shunt 50mV 20A

The Saftronics Battery Monitor Shunt 50mV 20A is a precision current sensing resistor designed for accurate measurement of DC currents in industrial and battery monitoring applications. This shunt operates by producing a small voltage drop (50mV) proportional to the current flow (up to 20A), allowing integration with voltmeters or monitoring systems to calculate current via Ohm's law. It is commonly used in battery management systems, DC motor controls, power supplies, and industrial equipment like stacker reclaimers, as indicated by the associated labeling. Key features include high accuracy, low resistance (approximately 2.5 mOhm), and robust construction for reliable performance in harsh environments. Advantages over similar products include its compact size for easy installation, durability in high-vibration settings, and compatibility with Saftronics drive systems. Drawbacks may include the need for precise calibration and potential heat generation at maximum loads, requiring adequate ventilation. This device enhances system efficiency by enabling real-time current monitoring, preventing overloads, and supporting predictive maintenance. Based on image analysis, the unit appears new or unused, still in original packaging, though the packaging shows signs of age and dust. No parent/child assets are visible. For detailed model decoding, Saftronics shunts follow a simple rating scheme (mV/A), with no complex alphanumeric codes found in searches. Comparable products from manufacturers like Vishay or Eaton offer similar specs but may lack Saftronics' integration with proprietary drives.
