Modular AC/DC supplies are low profile in 1U chassis

The modular supply is constructed in a compact, low profile, 1U mechanical chassis format which can accommodate up to four, single-slot, plug-in customer-selected output voltage modules.

They are designed to minimise audible fan noise, and 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 19 nominal output voltage options in the range 3.3 to 60V DC. Outputs are derived from one of four base, digitally controlled, module designs offering a wide voltage adjustment range.

The user can adjust and tailor the supply to the end application. The series minimises individual inventory items and supports fast turnaround delivery of products configured to exact customer requirements, claims the company.

Cooling fans in the centre of the supply further reduce audible noise and allow users to specify the airflow direction to suit the application. The full output power rating is available regardless of airflow direction.

The nanofleX 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 sub-set 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. Users can further refine the configuration during the system development phase.

The series complies with 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.

Supplies are covered with a three year warranty.
