Convection cooled miniature PSU increases reliability and reduces noise
The new convection cooling option delivers 260 W of output power across all output voltages and eliminates the fans and fan controllers required to cool conventional power supplies. The convection cooling option reduces costs and frees-up valuable system real-estate. As the Powerstax N-03751-PFC does not require forced air for full 260 W operation, the system designer no longer has to be concerned with channelling air over the PSU, simplifying thermal design. Removing the fans also significantly increases the reliability of the Powerstax N-03751-PFC and reduces audible noise of end products, making them ideal for office environments.
Where an end system may be used in different environments, customers can simplify system level design by specifying the convection cooled Powerstax N-03751-PFC and if required substituting the forced-air cooled version which offers the same very compact, low profile 5 x 7.7 x 2.3 mm (3.3 x 5 x 1.5 inches), packaging, connectors and layout, saving design time and costs.
The synchronous rectification technique of the Powerstax N-03751-PFC Series delivers exceptionally high efficiency, up to 93% in some models and all models feature active current sharing allowing up to four power supplies to be operated in parallel for high output power applications. An optional active OR-ing mosfet board is also available for N+1 redundant applications. Both 5 V standby and 12 V auxiliary outputs can be wired OR-able when the main output is disabled.
The Powerstax N-03751-PFC Series has a compact footprint of 3.3 inch x 5.0 inch (83.8 mm x 127.0 mm) and low profile of 1.5 inch (38.1 mm) suitable for use in 1U racks, an active PFC input over the range 90–264 VAC, an operating temperature range of –25 to +50ºC and meets a full range of international agency requirements, including RoHS, UL, DEMKO, CE Mark and FCC Class B. Output is protected against overvoltage, overpower, short circuit and over temperature.
