$25 Each Band NEW, Never Used.

This is a dual channel heavy duty and powerful type of "SCHOTTKY RECTIFIER" or called "DIODE".

It works like a check valve, which lets the electric current go one way.

Usually, this should be place between the battery and wind turbine to prevent reverse current flowing back from a battery through your wind turbine when there is no wind.

Max 30V (reverse blocking), can be use with 12V or 24V system.

Max 220A (forward current) each channel, both channel will be 440A total.

Max 150ºC/302ºF working temperture.

Lower forward voltage drop compare with others, that means more efficiency.

110A 0.48V drop use single channel. As little drop as better.

Unlike other seller, they won't list the manufacture and specification information.

You will surprise to see some other blocking diode drop more than 1 volt.
