Introducing Single-Phase and Three-Phase Full-Wave Rectifier Stacks
We are pleased to introduce our line of standard stack products, which are equipped with single-phase and three-phase full-wave rectification circuits.
Main Applications
Rectifier Circuits for Various Power Supplies
Our products have a proven track record in a wide range of applications that require a stable supply of power and long-term reliability. These applications include DC power supplies for power plants, rectifiers for electric railways, uninterruptible power supplies, and shaft generators for ships.
Product Features
- Extensive Product Lineup
We offer a wide range of stack products equipped with our own devices, ranging from low current 36A to high current 3500A. - A Wide Range of Standard Products
In addition to three-phase half-wave rectification, we also stock standard products with single-phase full-wave and three-phase full-wave rectification. Our self-cooling high-current products are ideal for large power supplies that are difficult to maintain after installation, as they do not require fan replacement.
