Bel Power Solutions announced the expansion of their high power portfolio with the TXP3500 Series, a maximum 3500W ac-dc power supply suitable for industrial, process and control and machinery applications. The TXP3500 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 TXP3500 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.

TXP3500 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 180- to 528-Vrms at up to 63Hz, 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 28kW.

The output voltage is adjustable, ranging from 10V to 50V, fully protected against overvoltage, overcurrent, over temperature 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 -20 to +55 degrees C.

RoHS compliant, the power supplies are safety agency certified per CSA/UL60950-1 and meet the requirements of EN 60950-1. The product meets the conducted and radiated EMI requirements of EN 55022-A.
