The CUI Inc. PSK-5D-9 is an internal AC-DC power supply designed for various applications. It provides a stable 9Vdc output with a maximum current of 555mA, delivering up to 5W of power. The unit operates with a wide input voltage range, accepting both AC (85-305 Vac) and DC (100-430 Vdc) sources.
Key electrical specifications include a typical efficiency of 80.5% at 230 Vac, a maximum ripple and noise of 100 mVp-p, and tight load and line regulation of ±1.0% and ±0.5% respectively. Protections such as over-voltage, over-current, and short-circuit are integrated for reliability.
This power supply is housed in a compact 1 x 1 inch encapsulated package, making it suitable for space-constrained designs. It operates across a wide temperature range of -40°C to +85°C. The PSK-5D-9 meets Class B emissions standards and is certified to safety standards including 62368, 61558, and 60335.
Mounting is via through-hole, and the package type is a 5-DIP module with 4 leads. Applications include ITE (Commercial) and Household Appliances.
