The PYQ50-72WS48 is a 50W 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 14 to 160Vdc input range and delivers a 48V output with an efficiency of up to 85% at 110Vdc input. The unit features 3000Vdc input-to-output isolation, remote on/off control with positive logic, and an adjustable output voltage range of -20% to +10%. It is potted for shock and vibration resistance, certified to IEC 62368-1, and tested to EN 50155 for railway use. Operating temperature ranges from -40°C to +100°C with a maximum case temperature of 100°C.
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.
