Ultra-compact SIP AC-DC PSUs get low-profile versions

September 24, 2014 // By Graham Prophet
CUI’s PBK series of ultra-compact SIP AC-DC power supplies now has right-angle versions. The low-profile PBK-B family is available in 1W, 3W and 5W configurations. The power modules measure as little as 35 x 25 x 13 mm, to deliver on-board AC-DC power conversion where board real estate is at a premium.

The high density PBK-B outputs 3.3, 5, 9, 12, 15, or 24 Vdc and can operate at AC input voltages between 85~264 Vac. For high voltage DC-DC applications, the modules also come in 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 (1 W and 3 W) and -25 to +85°C (5 W) for use in challenging environments.

The low profile PBK-B series meets internationally recognised UL 60950-1/EN 60950-1 standards and complies with EN55022 Class B limits for conducted and radiated EMC with few additional external components required. Via distribution they cost from $11.29 (100).
