TUALATIN, Ore. — CUI’s Power Group announced the addition of 3 W and 5 W 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 housed in compact packages measuring as small as 1.46 x 0.97 x 0.71 inches (37 x 24.5 x 18 mm), making them well suited for space-constrained low power ITE, industrial control, automation, and consumer electronics applications. Designed for easy installation, 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 afford engineers additional options for simpler design implementation.
These encapsulated modules feature 4 kVac input to output isolation, a universal input voltage range of 85 to 264 Vac, and a wide operating temperature range from -40 up to +70°C. The series also offer single output voltages of 3.3, 5, 9, 12, 15, and 24 Vdc, along 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 further carry a minimum MTBF of 300,000 hours at +25°C ambient, per MIL‑HDBK‑217F.
The PSK‑S3 and PSK‑S5B series are available immediately with prices starting at $8.01 per unit at 120 pieces through distribution.
