Performance. Trust. Innovation
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.
