1W Ac-Dc power supplies housed in ultra-compact SIP packages

Power supplies feature wide input voltage ranges from 85 to 305 Vac or 70 to 430 Vdc for high voltage dc-dc applications
CUI’s Power Group announces 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 SIP packages, respectively.

The vertical PBO‑1 series measures as small as 35 x 11 x 18 mm (1.38 x 0.43 x 0.71in), while the low profile, right-angle PBO‑1‑B series measures as small as 35 x 18 x 11mm (1.38 x 0.71 x 0.43in), 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 over current and continuous short circuit protections with auto recovery.

Wide operating temperature range

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