XP Power’s nanofleX series of configurable, modular, digitally controlled AC-DC power supplies is constructed in a compact, low-profile 1U mechanical chassis format that suits today’s space constrained designs, and can accommodate up to four single-slot plug-in output voltage modules. Designed to maximise efficiency and minimise audible fan noise, the nanofleX series can deliver up to 850 W from a universal input voltage or up to 1200 W from a high line source.

The four output module slots provide nineteen nominal output voltage options in the range +3,3 to +60 V d.c. Outputs are derived from one of four base, digitally controlled module designs offering a wide voltage adjustment range. This approach provides extensive flexibility and user adjustment to tailor the product to the end application, minimises individual inventory items and supports fast turnaround delivery of products configured to exact customer requirements in XP Power’s global configuration centres.

Cooling fans are positioned in the centre of the product, further reducing audible noise and allowing users to specify the airflow direction to suit their application. The full output power rating is available regardless of airflow direction.

The nanofleX platform supports both analog and digital control. The analog signals include AC OK (global), DC OK (global and local module) in addition to remote On/Off (global and local), voltage adjustment, remote sense and current share controls. The digital functions use a subset of the industry standard PMBus command protocol that include digital equivalents of all the analog signals and controls together with over-voltage, over-temperature, over-current and fan-fail warning functions.

A graphical user interface (GUI) facilitates the control and configuration of the nanofleX via an I2C interface using the PMBus commands, allowing users to interface with the power supply from day one and further refine the nanofleX configuration during the system development phase.

nanofleX complies with the internationally recognised medical and IT safety approval standards IEC/EN/ANSI/AAMI 60601-1 and IEC/EN/UL60950-1. It provides 2 x MOPP according to the third edition of the medical safety standard, and comes with a three-year warranty.
