Product Features
1. Supports continuous high current; easily handles high-power solar panels, energy storage batteries, and industrial equipment with stable, reliable, and cool operation.
2. Wide input voltage range (DC 5V–100V); perfectly compatible with 12V, 24V, 48V, and 72V systems, covering diverse application scenarios.
3. Effectively prevents reverse leakage from the battery back to the solar panel at night, improving system efficiency and extending battery lifespan.
4. Automatically isolates reverse-connected batteries and prevents backflow current from damaging equipment, providing a safety barrier for energy storage systems.
5. Near-zero conduction voltage drop; allows high current flow without the need for heat sinks.

Precautions
1. GND must be connected to the negative terminal.
2. Do not connect to AC power; cannot be used as a substitute for a rectifier bridge in AC rectification.
3. Input voltage must not be lower than 5V. When input voltage is below 8V, power loss and heat generation increase; please reduce the operating current.
4. Do not reverse the input positive and negative polarities.
Main Applications (Four Core Scenarios)
1. High-voltage power supply OR-ing (multi-power supply parallel redundancy)
48V/72V telecom power supplies, server/base station multi-power supply paralleling
Automatically isolates faulty power supplies and prevents backflow; ultra-fast 50ns turn-off
Replaces multiple Schottky diodes; minimal heat generation during high-current operation
2. Battery system reverse-connection/backflow protection
Electric vehicles (54V/72V/90V), energy storage battery packs
Prevents charger reverse connection, backflow during plugging/unplugging, and cross-current between batteries
100V rating Voltage rating covers the voltage range of most power batteries
3. Industrial/New Energy High-Voltage Reverse-Current Protection
PV junction boxes, micro-inverters (preventing reverse current from modules at night)
20–80V power tools, industrial control power path protection
