current protection and control: Designed as a diode controller for solar and DC power systems, it reliably handles up to 15A and manages current across a wide operating range of 328V so your system stays protected under typical PV, battery and DC distribution conditions. Minimized energy loss and heat: When active the device exhibits a very low forward voltage drop of just 20mV, significantly reducing conduction losses and heat generation compared with standard Schottky diodes. That improves overall system efficiency and lowers thermal stress on nearby components. Fast, reliable backflow prevention: The controller turns the diode off instantly whenever the output voltage exceeds the input, preventing reverse current flow and eliminating unwanted backfeed from batteries or downstream sources. This behavior helps protect panels, batteries and power electronics and improves system reliability. Simple integration and broad compatibility: Built to work with common solar setups and DC power systems operating between 328V and up to 15A. Use it anywhere you need a lowloss, automatic blocking diode function without the drawbacks of forwarddrop solutions. Practical performance advantages: Low conduction loss (20mV) reduces wasted energy and cooling requirements. Instantoff backflow protection reduces risk of battery discharge into panels or other sources. Robust 15A capability supports midrange PV arrays and battery systems. Typical applications Solar panel to battery systems: Prevents nighttime backflow from batteries into solar panels while minimizing losses during charging. Multisource or redundant supply systems: Automatically blocks reverse currents when one source voltage rises above another, enabling safe power combining or switchover without mechanical relays. Offgrid and mobile DC power setups: Protects batteries and sensitive loads in RVs, boats, or microgrids where efficient, compact, and automatic blocking is required. Key specifications Function: Diode controller with instant turnoff when output > input Voltage range: 328V Current capacity: up to 15A Forward voltage drop when on: approximately 20mV Why choose this device Solves the common tradeoff between efficiency and protection by combining very low forward voltage drop with dependable backflow blocking. Ideal when you need to preserve battery charge, reduce heat and improve the reliability of solar or DC power installations.
