PYQ75-36WS48 is a PYQ75 series 75W, 1/4 brick single output DC-DC converter that operates from an ultra-wide with a single output. The output voltage can be adjusted between -20% to +15% by using the trim terminal. Sense lines for the output voltage ensure a stable output voltage even with changing loads. It has efficiency and can operate in ambient temperatures of -40 to 105°C. The input-to-output isolation is 3,000VDC and the units are potted to provide a high resistance to shock and vibration. It includes overcurrent, overvoltage, and overtemperature protection. The converter is certified according to the 62368-1 safety standards and with additional circuits, it is also tested according to the EN 50155 railroad standard for electronic equipment in railroad vehicles.
