Delta Electronics Q48SR manual Features

Delphi Series Q48SR, 165W Quarter Brick Family DC/DC Power Modules: 48V in, 1.8V/40A out

The Delphi Series Q48SR Quarter Brick, 48V input, adjustable single output, isolated, open frame DC/DC converters are the latest offering from a world leader in power systems technology and manufacturing — Delta Electronics, Inc. This product family provides up to 165 watts of power or up to 60A of output current in an industry standard footprint. This product represents the next generation of design technology which may be utilized to provide high levels of current at very low output voltages required by today’s leading-edge circuitry. Utilizing an advanced patented thermal and electrical design technology; the Delphi Series Q48SR converters are capable of providing higher output current capability with excellent transient response and lower common mode noise. Featuring a wide operating output voltage range and high current at low output voltages, these units offer more useable power over a wide range of ambient operating conditions. The wide range trimmable output feature allows the user to both reduce and standardize part numbers across different and/or migrating voltage requirements. This model covers the output range of 0.8V to 1.9V at 40A.
