I just had a heck of a time trying to source a half-wave brake rectifier module, suitable for 480VAC input. I had to have a brake coil on an induction motor rewound after it shorted and took out the rectifier pack. My motor re-wind shop wanted over $400 for a rectifier.
Amazon has lots for sale, all from dodgy third-party shippers which I'm sure totally aren't clone / knockoff parts - trust me, bro! I didn't feel like rolling the dice and trusting a maybe counterfeit part with 480VAC.
Practically no other websites like McMaster, Galco, or Zoro/Grainger sell them. I had to call my Mayr sales rep and order one direct from Mayr (they make electromagnetic brakes and clutches). Still overpriced, but not $400 overpriced.
It was honestly weird to have no trusted vendors sell a compatible part. It's not like I needed a particular model number either. Just a half wave rectifier with a 600VAC rating.
