The PYD20-72WS05 is a 20W isolated DC-DC converter in a 2 x 1 x 0.4 inch plastic case, designed for industrial and railway applications. It operates from an 8.5 to 160Vdc input range, delivering a 5V output at up to 4A with 86% efficiency at 72Vdc input. The unit features 3000Vac input-to-output isolation, remote on/off control with positive logic, and an adjustable output from -20% to +15%. It complies with IEC 62368-1 safety standards and meets EN 50155 for railway use. Operating temperature ranges from -40 to 105°C, with a maximum case temperature of 105°C. Ripple and noise are specified at 75mVp-p, and it supports up to 6800µF external load capacitance. The converter is potted for shock and vibration resistance and has a typical weight of 28.5g.
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.
