Bel Power Solutions Announces Expansion of High Power Portfolio with TXP4000 Series for Industrial Applications

Fan-cooled PSU Offers a Maximum of 4000 W and Adjustable Output Voltage

Santa Clara, CA [March 19, 2020] - Bel Power Solutions today announced the expansion of their high power portfolio with the TXP4000 Series, a maximum 4000 W AC-DC power supply suitable for industrial, process and control, railway and machinery applications.

The TXP4000 Series of AC-DC converters employs a PFC front-end stage and an isolated DC-DC stage to convert the 3-phase input voltage to a low DC output voltage in a broad array of industrial applications where high efficiency is a requirement, with emphasis on both reliability and long product life. The TXP4000 Series also include DSP technologies which enable monitoring of electrical parameters (including input voltage of all 3-phases) and allow control of the PSU from a system controller. RS485 / CAN bus communication is available to command, monitor and provide diagnostic information that can be used to interface with a system controller.

TXP4000 Series power supplies feature a compact footprint (135 x 85 x 465 mm / 5.31 x 3.35 x 18.31 inches) and accommodate the worldwide 3-phase input voltage range of 350-528 Vrms at up to 63 Hz, with active current share system available. Units can be used in parallel (8 units) or serial configurations (4 units), generating a maximum output power of 32 kW. The output voltage is adjustable, ranging from 30 V to 137.5 V optimized to 110 V, fully protected against overvoltage, overcurrent, overtemperature and short circuit situations. 12 V auxiliary output is also available. A highly efficient thermal design with an internal fan cooling system permits their use over a wide operating temperature range of -25° to +55°C.

RoHS compliant, the power supplies are safety agency certified per CSA/UL60950-1 and meet the requirements of EN60950-1. The product meets the conducted and radiated EMI requirements of EN 55022-A

The TXP4000 is available from Digi-Key and Mouser. Customers can also request a quote through Bel’s website. For more detailed product information, download the TXP4000 Series datasheet.
