Description
90 Amp, 3 Phase 1200 Volt Rectifier
EMP Hardened (When properly grounded)
3 Phase AC to DC Rectifier
Works with 12 volt to 1200 volt systems
This unit will handle a massive amount of power. Perfect for medium to large residential and commercial turbines and generators. This AC to DC, three phase rectifier uses six, 30 amp continuous duty (at 90c), 120A surge (per diode) at 1200 volts. The diodes are fully embedded in a electrically non-conductive epoxy/mortar mix. This mortar allows for even heat distribution to the box itself to allow for proper cooling at high amps. A high temperature epoxy is then used to encase the entire assembly of diodes, copper and mortar and bond it securely to the Hoffman outdoor enclosure.
The Hoffman Nema 3R, enclosure measures 4.1″ wide, by 6.5″ high by 4.1″ deep. It has 2 knockouts on the bottom for easy access. Has a lockable cover. The unit weighs 5 lbs.
The rectifier is capable of running at 90 amps continuous and 720 amps surge at nearly any voltage a wind turbine might produce. A 48v wind turbine will probably produce around 75 volts with a strong to moderate wind.
This rectifier at 75 amps would allow more than 5625 watts of power at 75 volts.
The rectifier itself uses 6 diodes rated at 50 amps each at 25c. Theoretically, it could handle even more than 90 amps but cooling must be taken into account and is actually the limiting factor. Please see the diode specification sheet below.
A/C power is terminated to the 3 screws in the middle.
Outgoing D/C is provided on the two screws on each side.
