CUI’s Power Group added 3W and 5W models to its line of low power, encapsulated AC-DC power supplies. Available in board mount, chassis mount, wire lead, and DIN-rail configurations, the single-output PSK‑S3 and PSK‑S5B series are as small as 37 x 24.5 x 18 mm.

The wire lead PSK‑S3‑L and PSK‑S5B‑L series, chassis mount PSK‑S3‑T and PSK‑S5B‑T series, and DIN rail mount PSK‑S3‑DIN and PSK‑S5B‑DIN series feature 4 kVac input-to-output isolation, an input voltage from 85 to 264 Vac, and an operating temperature range from -40 to +70°C. Available in single-output version delivering 3.3, 5, 9, 12, 15, and 24 Vdc, with over current, over voltage, and continuous short-circuit protections.

All models are certified to the new IEC 62368-1 safety standard for ICT and AV equipment, while meeting CISPR32/EN55032 Class A limits for conducted and radiated emissions. Featuring class II construction, these encapsulated AC-DC power supplies carry a minimum MTBF of 300,000 hours at +25°C ambient, per MIL‑HDBK‑217F.
