150 Amp, 12V - 400V Three phase rectifier - AC to DC Wieggman 3R Rain tight box

150 Amp, 3 phase Rectifier Center

3 Phase AC to DC Rectifier

Works with 12 volt to 400 volt systems

This unit will handle a massive amount of power. Perfect for medium to large residential turbines and generators. This AC to DC, three phase rectifier uses six 70 amp, 400 volt stud diodes press mounted into aluminum plates. The aluminum plates are fully embedded in a electrically non-conductive epoxy/mortar. 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 aluminum and mortar and bond it securely to the Wiegmann enclosure. Not shown are the nuts and washers included for wire termination.

The Wiegmann Nema 3R screw enclosure measures 6" wide, by 6" high by 4" deep. It has 3 knockouts on the bottom for easy access. Has a lockable cover. The unit weighs 9 lbs.

The rectifier is capable of running at 75 amps continuous and 150 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 70 amps each. Theoretically, it could handle even more than 150 amps but cooling must be taken into account and is actually the limiting factor.

A/C power is terminated to the 3 screws in the middle.

Outgoing D/C is provided on the two screws on each side.

Not shown are the washers and nuts for termination.

Brackets with 1/4" holes are on both top and bottom for easy mounting.

Shown with cover flipped to allow for lock.

Cover flipped with lockable slot upwards under top lip.

How to compare this three phase rectifier with others

  • Does it provide the capacity you need?
  • Do they include a convenient method of installation?
  • Will it allow termination of large wire?
  • Is the rectifier insulated (lightning proof)?
  • Does the rectifier have adequate heat dissipation?
  • Is the enclosure weather resistant, and rain tight?
