Engineered Systems
Hybrid DC Power
800 VDC architectures, DC-link distribution, and electro-hydraulic drivetrains that replace 480 VAC with a DC bus.
The problem class
High-power mobile equipment traditionally runs a diesel engine sized for the worst five minutes of the duty cycle, idling through the rest. AC distribution adds transformers, switchgear, and conversion losses at every stage. A hybrid DC architecture sizes generation for the average load, covers peaks from storage, and moves power on a single DC bus, so the machine gets smaller, quieter, and cheaper to run.
The Envoltz architecture
- An 800 VDC bus as the backbone, with generation, storage, and loads all landing on the same DC link
- Variable-speed generation that runs at the efficient point instead of a fixed 1800 RPM
- Battery storage sized for peak shaving, transient response, and silent operation windows
- Electro-hydraulic drivetrains and e-drive enclosures for machines that used to take a PTO
- One controller architecture, one CAN protocol standard, commands in physical engineering units

The engineering artifacts behind it
Every program ships with a revision-controlled document set. This is what your bid evaluator gets to read, and what your technicians work from for the life of the system.
