With an extra wide input range of 12:1 (14V to 160V) the PQB50U-72S delivers 50W in quarter-brick packaging, for power designers addressing EN50155 applications (one unit covering all bus voltages). In full brick packaging, the PFB600W-110S is a 600W unit within a 4:1 input voltage range of 43V to 160V, accommodating 72V, 96V and 110V bus voltages. Both products can be operated from -40°C up to +100°C case temperature, matching very demanding and ruggedized requirements such as in construction vehicles, mining equipment & heavy machinery process control.
Industry and railway power designers, Powerbox notes, always face challenges to optimize board power solutions when designing standardized equipment for worldwide operation on a very large variety of system bus voltages. In the railway industry, designers continuously seek the best power architecture to operate within the overall EN50155 input voltage range, from 24V up to 110V (including continuous operation in the 14.4V brownout condition and 154V transients). To guarantee board power designers the highest level of flexibility, the PQB50U-72S has been developed to deliver full and stable power within an extended input voltage range from 14V up to 160V.
In iIndustrial and the forthcoming Industry 4.0 applications, system designers have to guarantee full performance in a multitude of applications operating from 24V to 72V and fixed industrial battery backup systems using 110V in which the quality of line is often disturbed. In those applications, the PQB50U-72S is designed to sustain high level of line disturbance within a range as low as 14V to a 200V surge. In such environments, the PQB50U-72S guarantees full output performance, simplifying design for systems architects and by having only one power module covering all ranges of input voltage, thus reducing inventory.
PQB50U-72S comes in a standardized DOSA quarter-brick package. The module is available in four output voltages (5V/6A ; 12V/4.2A ; 24V/2.1A and 48V/1.05A). The device sustains 200V/100 msec surge input voltage, includes short circuit
