Miniature SIP AC-DC Supplies Maximize Board Space Deliver up to 5W

CUI Inc. has launched their smallest ac-dc power supplies yet with the release of the PBK SIP series. Available in 1W, 3W, and 5W 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 and 264 Vac.

For high-voltage dc-dc applications, the modules also provide a dc input range spanning 100 to 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.
