New digitally controlled 1U configurable power platform

XP Power has announced the nanofleX series of configurable digitally controlled AC/DC power supplies. This modular supply 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 customer selected output voltage modules. Designed to maximise efficiency and minimise audible fan noise, the nanofleX series can deliver up to 850W from a universal input voltage or up to 1,200W from a high line source. The four output module slots provide nineteen nominal output voltage options in the range +3.3VDC to +60VDC. Outputs are derived from one of four base, digitally controlled, module designs offering a wide voltage adjustment range. This approach provides ultimate 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 our 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 platform supports both analogue and digital control. The analogue 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 analogue signals and controls together with over voltage, over temperature, over current and fan fail warning functions. A 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. The series 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 3rd edition of the medical safety standard.
