SPECIFICATIONS

Product Features
1. Sustained high current output, easily handling high-power solar panels, energy storage batteries, and industrial equipment—stable, reliable, and heat-free
2. Wide DC input voltage range of 5V–100V, fully compatible with 12V, 24V, 48V, and 72V systems, covering a wide range of applications
3. Effectively prevents reverse leakage from the battery to the solar panel at night, improving system efficiency and extending battery life
4. Automatically isolates reverse-connected batteries to prevent backflow of current that could damage equipment, providing a safety barrier for energy storage systems
5. Near-zero on-state voltage drop, enabling high current flow without the need for a heat sink

Precautions
1. GND must be connected to the negative terminal.
2. Do not connect to AC power; do not use as a substitute for a rectifier bridge in AC rectification circuits.
3. The input voltage must not be lower than 5V. When the input voltage is below 8V, power loss increases and heat generation rises; please reduce the current accordingly.
4. Do not reverse the input positive and negative terminals.

Main Applications (Four Core Scenarios)
1. High-Voltage Power Supply OR-ing (Multi-Power-Supply Parallel Redundancy)
48V/72V communication power supplies, server/base station multi-power-supply parallel configurations
Automatically isolates faulty power supplies to prevent backfeed, with ultra-fast 50 ns shutdown
Replaces multiple Schottky diodes while generating minimal heat even at high currents
2. Battery System Reverse Connection/Backfeed Protection
Electric vehicles (54V/72V/90V), energy storage battery packs
Prevents charger reverse connection, reverse current during plug insertion/removal, and battery interconnection
100V voltage rating covers most power battery voltages
3. Industrial/New Energy High-Voltage Reverse Current Protection
PV junction boxes, micro-inverters (prevents nighttime module reverse current)
20–80V power tool and industrial control power path protection
