The CUI Inc. PSK-30D-3 is an internal AC-DC power supply designed for various applications. It features a wide input voltage range of 85 to 305 Vac and operates across a broad temperature range from -40°C to +85°C.
This power supply delivers a 3.3Vdc output voltage with a maximum current of 6A, providing up to 20W of power. Key electrical specifications include an efficiency of 85% at 230 Vac input, line regulation of ±0.5%, and load regulation of ±2% for the 3.3V model. It also includes over-voltage, over-current, and short-circuit protections.
The PSK-30D-3 is housed in a 4-DIP Module package and is designed for through-hole mounting. It is certified to safety standards such as 62368, 61558, and 60335, and meets Class B emissions standards.
