March 19, 2020 by Paul Shepard

Bel Power Solutions announced the expansion of their high-power portfolio with the TXP4000, a maximum 4000W ac-dc power supply suitable for industrial, process and control, railway and machinery applications. Units can be used in parallel (8 units) or serial configurations (4 units), generating a maximum output power of 32kW.

The TXP4000 includes DSP technology which enables monitoring of electrical parameters (including input voltage of all 3-phases) and allows 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 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- to 528-Vrms at up to 63Hz, with active current share system available. The output voltage is adjustable, ranging from 30V to 137.5V optimized to 110V, fully protected against overvoltage, overcurrent, overtemperature and short circuit situations.

A 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°C 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.
