Product overview and key benefits efficiency replacement for current diodes: Designed for 3–28 V systems and continuous currents up to 15 A, this lowvoltage differential diode controller reduces energy loss and heat compared with standard diodes, improving overall system efficiency and component life. Prevents reverse current and protects batteries: The fast reaction mechanism detects millivoltlevel changes and immediately blocks reverse current when the output exceeds the input, preventing backflow that can discharge batteries or damage solar panels. Low power draw for batterypowered systems: With only 11 uA static current independent of load, it preserves stored energy and is ideal for lowenergy or batterybacked systems. Low forward voltage drop for minimal heat: Typical forward drop around 20 mV when active significantly reduces dissipation versus Schottky diodes, lowering thermal stress and helping systems run cooler and longer. What it does and why you need it Reliable antirefill protection: Automatically prevents reverse charging of batteries and reverse feeding into panels or supplies, improving safety and reliability in mixedsource setups. Improves energy harvest: Lower forward voltage drop and minimal standby current mean more usable energy reaches your battery or load, which is critical for offgrid, marine, or remote installations. Stable under varied conditions: Fast detection of millivoltlevel differences maintains protection and performance as sunlight, load, or source voltages change. Compatibility and typical applications Designed for solar panel systems, AC/DC adapters, and battery charging schemes that operate between 3 V and 28 V and require up to 15 A continuous current. Use scenarios: 1) Small offgrid solar system: Prevents battery discharge into panels at night, maximizes charging efficiency during the day, and reduces heat in the controller circuitry. 2) Multisource power setups: Protects batteries and loads when switching between solar, grid, and generator sources to avoid crossfeeding or backflow. 3) Batterybacked AC/DC adapter or UPS: Minimizes standby drain and heat while ensuring fast isolation when adapter output falls below battery voltage. Performance and operating limits Input voltage: 3–28 V Maximum current: 15 A ( current controller suitable for solar/battery applications) Typical forward voltage drop: 20 mV when active Static current draw: 11 uA (independent of load) Fast reaction to millivoltlevel changes to prevent reverse current Operating temperature range: 40 C to 125 C Why this product stands out Combines ultralow forward drop and very low quiescent current for measurable energy savings versus traditional and Schottky diodes. Fast, millivoltlevel detection ensures prompt antirefill action and stable performance in changing environmental or load conditions. Straightforward compatibility with common solar, adapter, and battery charging systems without requiring complex configuration. Note: Designed to standard current diodes in compatible 3–28 V, up to 15 A applications; verify system voltage and current requirements before installation.
