AntiReverse Irrigation Diode Constant Current Power Module A compact electronic module that combines antireverse diode protection and constant current control for battery and solar charging systems. Designed to prevent backflow of current and to deliver steady current to loads, this module helps protect batteries and connected equipment while improving system reliability. Key benefits Prevents reverse current flow from batteries to solar panels or other sources, reducing unwanted discharge and protecting components. Provides constant current regulation to protect sensitive loads and stabilize charging, helping maintain predictable performance. Simple integration into DC systems for rapid deployment in solar, battery, and irrigation applications. Compact board form factor suitable for installation inside control boxes or small enclosures. Main functions Antireverse diode protection to stop backflow and prevent battery discharge through the charging circuit when the source is inactive. Constant current output to limit or stabilize current supplied to a load or battery during charging or operation. Passive boardlevel design for reliable longterm operation in DC power systems. Compatibility Compatible with DC battery systems and common smallscale solar photovoltaic setups. Suitable for irrigation controllers, solenoid valves, pumps, LED lighting, and other lowvoltage DC loads that need backflow prevention and current stabilization. Can be used with a range of battery types where constant current control and reverse current protection are required. Physical attributes and construction Boardlevel module designed for easy mounting inside enclosures and integration into existing wiring runs. Constructed with standard PCB materials and electronic components appropriate for lowvoltage DC use. Terminal or pad connections allow straightforward wiring to input source, output, and battery as required. Performance notes Provides reliable antireverse protection combined with steady current behavior to reduce stress on batteries and loads. Low voltage drop and stable response under typical operating conditions for smallscale solar and battery systems. Designed for continuous DC operation in charging and power delivery roles. Practical use scenarios 1) Solar battery charging: Install the module between a photovoltaic panel array and a battery bank to prevent nighttime backflow into the panels while providing a controlled charging current to protect the battery. 2) Irrigation control systems: Place the module in the power line to solenoid valves or controllers to prevent reverse current from batteries and to limit inrush current to valves and pumps. 3) Offgrid lighting and pump circuits: Use the module to deliver steady current to LED strings or DC pumps while preventing battery discharge through the power source when the supply is not active. Installation tips Observe correct polarity when wiring to ensure the antireverse function operates as intended. Mount inside a protected enclosure to avoid moisture and mechanical stress in field installations. Verify system voltages and current requirements before use to confirm compatibility with the module and connected components. This module offers a practical combination of reverse current protection and constant current behavior for small DC power systems, improving protection and predictability without complex configuration.
