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 TLP5000-1048 is a 5 kW, 3-phase AC-DC converter with adjustable DC output. Liquid cooling (no fan) makes this power supply suitable for a wide variety of high power industrial applications. Emphasis is given on reliability and long life. Parallel operation is possible for up to 12 units (up to 60 kW). CAN bus communication interface is used for command, monitoring and diagnostic information that can be supplied to a system controller.
