Bel Launches TLP5000 Series Liquid-Cooled 3-Phase AC-DC Converters for High-Power Industrial Applications

Bel Fuse Inc., a leading global manufacturer of trusted components, systems, and solutions for mission-critical applications across industrial, aerospace and defense, and data solutions markets, launched its TLP5000 Series, a new generation of liquid-cooled, high-power 3-phase AC-DC converters designed to meet the growing demands of industrial systems operating in extreme conditions. Built for applications such as high-power laser cutting, winding machines, and spinning mills, the platform delivers the reliability and robustness engineers need in demanding environments.

"The shift to liquid cooling is enabling a new class of high-power systems to operate reliably in environments where conventional solutions fall short," said Fabio Luconi, Business Development Manager Industrial & Medical. "With the TLP5000 Series, we're simplifying integration while giving engineers the scalability and control they need for next-generation industrial applications."

While traditional power supplies use forced-air cooling, the rugged AC-DC converter integrates a liquid cooling system with a built-in cooling plate, which eliminates the need for fans and significantly improves reliability, thermal efficiency, and product lifespan. The TLP5000 Series is a robust solution that can operate effectively in polluted environments, making it ideal for defense, industrial automation, and other harsh-condition deployments.

The converter's adjustable output voltage provides added design flexibility, allowing engineers to implement it across a wide range of high-power use cases and withstand continuous high-performance for a long lifetime. The TLP5000 Series also supports parallel operation with active current sharing, enabling scalable configurations up to 60 kW.

To support modern industrial architectures, the series includes CAN bus communication for real-time monitoring, control, and diagnostics. Hot-plug connectors further enhance system uptime by allowing maintenance or replacement without requiring a full system shutdown, which is essential for automated environments and smart infrastructure where continuous operation is critical.
