Power supplies can be used in parallel or serial configurations

Bel Power Solutions has 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 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 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. The power supplies feature a compact footprint (135mm x 85mm x 465mm) and accommodate the worldwide three-phase input voltage range of 180Vrms - 528Vrms at up to 63Hz, with active current share system available. Units can be used in parallel (8 units) or serial configurations (four 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. 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 -20C to +55C. 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.
