The PYQ75-36WS28 is a 75W isolated DC-DC converter in a quarter-brick package measuring 57.9 x 36.8 x 12.7 mm, designed for industrial and railway applications. It operates from a 9 to 75Vdc input range with a 28V output, adjustable between 22.4V and 32.2V, and delivers up to 2.67A at 90% efficiency. The unit features 3000Vac input-to-output isolation, remote on/off control with positive logic, and output sense lines for voltage regulation. It meets IEC 62368-1 safety standards and is tested to EN 50155 for railroad use. Operating temperature ranges from -40°C to 105°C, with a maximum case temperature of 105°C. The converter is potted for shock and vibration resistance, complies with MIL-STD-810F and EN61373 for environmental durability, and has an MTBF of 780,000 hours at full load. No minimum load is required.
The PY family are pcb-mountable DC-DC converters in various package sizes with output powers ranging from 20 to 200W.
The family's ultra-wide input voltage range (from 8.5 to 160V - model dependent) enables a single converter to be used in multiple applications. With its approval to EN 50155, it is also suitable for railway applications.
Its high efficiency results in low heat generation and the potted construction promises high shock and vibration performance which together with the wide operating temperature range make these devices suitable for nearly any situation.
Additionally, heat sink kits are available to simplify integration when contact cooling is not possible.
