  • Compact design with integrated control system
  • Air-cooled power section
  • Easy commissioning and service

Add to compare

The Innomotics PR150 Double 6-pulse rectifier is a thyristor-based rectifier system designed for green hydrogen production via electrolysis. It converts Alternating Current (AC) from the grid into Direct Current (DC) and provides higher current capacity compared to the single configuration. The system achieves efficiency up to 99% and is built with rugged thyristor technology to ensure high reliability. It features a compact cabinet design with integrated control, eliminating the need for an external control cabinet. The air-cooled design minimizes cooling complexity and utilizes proven SINAMICS components for consistent performance.

Use Cases
