Power supply for immerged computing applications

Powerbox has released its ‘industry-first’ power supply solution for immerged applications such as hyper loaded computing machines. The OFI600A12 is claimed to be the first commercial power supply created to satisfy immerged applications specifications and guarantee the highest level of safety for system and operators. With its built-in digital supervising functions, in just a few minutes, the solution can be factory reconfigured to satisfy specific tasks and demands.

The solution is based on an interleaved transition mode PFC design with an LLC converter as second stage. It is intended to have the lowest possible inrush current, less than 10A at 264VAC. The product has an input voltage of 187 to 265VAC, dual outputs including a master 12V/600W and an independent auxiliary of 5V/10W, and its efficiency is up to 93%.

The solution incorporates remote On/Off, remote reset, over-current and over-voltage protection and complies with safety and EMC regulations. Dependant on the application, output protection may be needed to be one of a variety of different configurations, satisfying this requirement, the solution can be reconfigured as appropriate. Based on firmware defined profiles and the output protection configuration, the mode of operation can be factory selected in a few minutes to satisfy the demands of particular applications. The unit is protected by a conformal coating and complies with the RoHS and REACH directives.

“With increased concerns for the environment and energy optimisation, immersed data centres are becoming widespread, and a number of industrial embedded applications have adopted immersed computers requiring compliant power supplies that are designed, tested and certified to work safely when immerged in a cooling fluid.” Said Patrick Le Fèvre, Powerbox’s chief marketing and communication officer.
