Compact SIP AC/DC power supply offers right angle versions

The low-profile PBK-B family is available in 1, 3 and 5W configurations. And measure 35 x 25 x 13mm for where board real estate is a premium.

Single output voltages are 3.3, 5, 9, 12, 15, and 24V DC and the supplies can operate at AC input voltages between 85 to 264V AC. For high voltage DC/DC applications, the modules also provide a DC input range spanning 100 to 400V DC. All models are designed for 3,000V AC/60s input to output isolation. They also have over current and continuous short circuit protection, and can function at a wide operating range from -40 to 85°C (1 and 3W models) and -25 to 85°C (the 5W model).

The supplies meet internationally recognized UL 60950-1/EN 60950-1 standards and comply with EN55022 Class B limits for conducted and radiated EMC with few additional external components required.  They can be used in automation equipment, industrial systems, security applications, and telecommunication equipment.
