1W AC-DC Power Supplies Housed in Ultra-Compact SiPs

CUI’s Power Group today announced the addition of two models to its PBO family of ultra-compact AC-DC power supplies. Outputting 1W of continuous power, the open frame PBO‑1 and PBO‑1‑B series are housed in vertical and right-angle system in packages (SiP), respectively. The vertical PBO‑1 series measures as small as 35 x 11 x 18 mm (1.38 x 0.43 x 0.71 in), while the low profile, right-angle PBO‑1‑B series measures as small as 35 x 18 x 11 mm (1.38 x 0.71 x 0.43 in), making them ideal for industrial systems, automation equipment, security, telecommunications and smart home devices where limited board real-estate is a factor.

These high-density power supplies feature wide input voltage ranges from 85 to 305 Vac or 70 to 430 Vdc for high voltage dc-dc applications. The PBO‑1 and PBO‑1‑B come available with single output voltages of 5, 9, 12, 15, and 24 Vdc and offer 3000 Vac input to output isolation. Both series also offer a wide operating temperature range from -40 to +85°C at full load as well as overcurrent and continuous short circuit protection with auto recovery.

All models further feature class II construction, carry UL 60950-1 safety approvals, and bear the CE safety mark.

The PBO‑1 and PBO‑1‑B series are both available immediately with prices starting at $4.74 per unit at 100 pieces through distribution.
