Frequently Asked Questions

  • Alta’s rectifiers are designed as part of integrated electrification systems, optimised for high power, continuous operation, and demanding environments rather than standalone industrial use.

  • Yes. Power rating, cooling method, control integration, and electrical characteristics can be configured to suit specific applications and system architectures.

  • Yes. Rectifiers can be integrated within regenerative braking architectures, enabling recovered energy to be stored in batteries or redistributed within the system.

Converting Power for
High-Demand Systems

Alta’s AC–DC rectifiers convert alternating current into stable direct current for use in high-demand electrification systems. Designed for industrial, rail, and heavy mobility applications, they form a critical part of traction power systems, charging infrastructure, and energy management architectures.

Beyond basic conversion, Alta’s rectifiers are engineered to deliver reliable, high-quality DC power under fluctuating loads, harsh operating conditions, and continuous duty cycles. Each system is configured to suit the specific electrical, thermal, and control requirements of the application.
