Bel Power Solutions Announces Expansion of High Power Portfolio with TXP4000 Series

Bel Power Solutions has announced the expansion of its high power portfolio with the TXP4000 Series, a maximum 4,000W 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 three-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 three-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 (135mm x 85mm x 465mm / 5.31in x 3.35in x 18.31in) and accommodate the worldwide 3-phase input voltage range of 350-528Vrms at up to 63Hz, with active current share system available. Units can be used in parallel (eight units) or serial configurations (four units), generating a maximum output power of 32kW. The output voltage is adjustable, ranging from 30 V to 137.5V optimized to 110V, fully protected against overvoltage, overcurrent, overtemperature and short circuit situations. 12V 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 using the enquiry form on this page.

Power in railway rolling stock originally involved traction, lighting and rudimentary signalling with typically raw 110VDC from the on-board batteries.
