Appears to be nothing more than an aftermarket RE-Gen drive. If you read the PDF you'll see that it mentions all these companies that use this technology. Yep they all do. Just not THIS drive.
The logo has an maple leaf (Canada) and IPC. I researched IPC and they have several aftermarket regen drives. This is the same company that makes a lot of aftermarket products. Like Generator Field regulator to replace open loop control. 6970 close loop operator.
Last I heard Mike Salich was still on their engineering team, and he is one smart cookied.
All these aftermarket products are out there, but wedding them to the current system is the trick. Support from the manufacturer is critical when installing these components.
