85 Amp -- 600! Volt Blocking Diode
Prevents Reverse current flow (discharge), in Solar and DC wind turbines.
Works with 12 volt through 600 volt systems.
This is the same diode used in our B170 Unit.
Rated at 85 amps and nearly any voltage your energy system might produce, makes it a perfect candidate for medium to large solar arrays with high wattage outputs, and high wattage DC turbines. Combine multiple diodes in parallel for higher current flow. Please note: Proper mounting to a heat sink or metal plate is required for proper heat dissipation.
Here is the manufacture datasheet on this diode . 85hf60.pdf
Why do I need a blocking diode? Solar panels require some form of reverse flow protection or they will discharge your batteries at night. DC wind turbines require a blocking diode or the batteries will actually attempt to turn the turbine backwards in light or no wind conditions. If you have a three phase AC output wind turbine, you do not need a blocking diode, instead you need a 3 phase rectifier, please see our store listings for three phase rectifiers. Solid state solar charge controllers often have built in reverse current flow prevention and therefor you may not need a blocking diode with some solid state charge controllers. Most diversion controllers utilizing relays and/or solenoids do not prevent reverse current flow, and thus a blocking diode is required with many diversion controllers. This blocking diode is also useful for single phase AC hydro and wind turbines.
