The PYD20-72WD15 is a 20W isolated DC-DC converter in a 2 x 1 x 0.4 inch plastic package, designed for rail and industrial applications. It provides dual ±15V outputs with a 3,000Vac input-to-output isolation, operates from an 8.5 to 160Vdc input range, and achieves up to 89% efficiency at 110Vdc input. The unit supports remote on/off control with positive or negative logic, has a 100mVp-p output ripple, and operates across -40 to +105°C ambient temperature. It meets IEC 62368-1 safety standards and is tested to EN 50155 for railway electronics. The case is potted for high shock and vibration resistance, and the device includes overcurrent, overvoltage, and overtemperature protection with automatic recovery.
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.
