Bel Fuse Inc. (United States) - Press Release: Ideal for Laser Applications with Parallel Operation up to 16 Units (57.6 kW).

Bel Power Solutions, a Bel group company (NASDAQ: BELFA and BELFB) and premier global manufacturer of power management devices, today announced the TCP4000 Series of fanless, three-phase 4000 W AC-DC converters, suitable for a variety of industrial applications, including semiconductor lasers and plasma generators, as well as process and control applications.

The TCP4000 Series converts worldwide three-phase input voltage (180 - 528 Vac) to an adjustable low voltage, from 30-100 Vdc, optimized at 90 V, which is ideal for semiconductor lasers. The TCP4000 also includes filtering and high specification output e-caps with high ripple current rating, high temperature rating and long life, making it ideal for semiconductor cutting, drilling, welding, marking, patterning and other processing techniques using lasers.

The TCP4000 Series’ fast output voltage set response time of less than 5 milliseconds can be used for direct regulation of the power for the whole laser system. It offers low voltage droop, which is important when powering laser drivers to maintain constant and consistent power to the laser diode, which impacts the regulation and quality of the light.

Conduction cooling makes this power supply series ideal for a wide variety of industrial applications that can use conduction or liquid cooling, where the environment may not be suitable for the use of fans. The TCP4000 Series offers active or passive current sharing of up to 16 units, for a total power output up to approximately 57.6 kW. Output bus bars are offered to reduce parasitic inductance, which can be an issue with a high pulse load operation. These power supplies also offer RS485 bus communication to command, monitor and provide diagnostic information that can be used to interface with a system controller.

The TCP4000 Series is SEMI F47 compliant, which defines requirements for input voltage sags (interruption), which are specified for industrial environments and are often required by semiconductor manufacturers. Other certifications include RoHS and EN62368-1, as well as the conducted and radiated EMI requirements of EN EN55011-A. The TCP4000 Series measures 400 x 85 x 103 mm.

The TCP4000 Series is an expansion of Bel Power’s enclosed high power portfolio, which offer single-phase and three-phase inputs to serve a wide variety industrial, broadcasting and telecom applications. Customers can request a quote through Bel’s website. For more detailed product information, download the TCP4000 datasheet. The TCP4000 is currently available from Digi-Key, Mouser, Avnet EU & Master Electronics.
