CUI Inc launched their smallest AC/DC power supplies yet with the release of the PBK ultra-compact SIP series. Available in 1 W, 3 W, and 5 W families, the modules measure as small as 1.38 x 0.43 x 0.94 in. (35 x 11 x 24 mm), occupying less pcb real-estate than other conventional ac-dc power supplies, thus allowing designers to fully maximize space where on-board ac-dc power conversion is required.

Today, CUI Inc launched their smallest ac-dc power supplies yet with the release of the PBK ultra-compact SIP series. Available in 1 W, 3 W, and 5 W families, the modules measure as small as 1.38 x 0.43 x 0.94 in. (35 x 11 x 24 mm), occupying less pcb real-estate than other conventional ac-dc power supplies, thus allowing designers to fully maximize space where on-board ac-dc power conversion is required.

The high density PBK series is offered in single output voltages of 3.3, 5, 9, 12, 15, and 24 Vdc and can operate at ac input voltages between 85~264 Vac. For high voltage dc-dc applications, the modules also provide a dc input range spanning 100~400 Vdc. All models are designed for 3,000 Vac/1 Min input to output isolation, have over current and continuous short circuit protection, and can function at a wide operating range from -40 to +85°C (1W and 3W) and -25 to +85°C (5W) for use in challenging environments.

The SIP packaged PBK series meets internationally recognized UL 60950-1/EN 60950-1 standards and complies with EN55022 Class B limits for conducted and radiated EMC with few additional external components. They are ideally suited for a range of applications including automation systems, industrial systems, and telecommunication equipment.

The PBK Series is available through distribution starting at $9.00 for 100 pieces. Please contact CUI for OEM pricing.
