Digital controlled AC/DC power supplies meet space constraints
AC/DC power supplies from XP Power in the nanofleX series are configurable, digitally controlled, modular supplies.AC-DC power supplies. They are housed in a compact, low profile 1U mechanical chassis format, and can accommodate up to four single-slot plug-in customer selected output voltage modules.
The supplies are designed to minimise audible fan noise. They can deliver up to 850W from a universal input voltage or up to 1,200W from a high line source. Cooling fans are positioned in the centre to reduce audible noise; users can specify the airflow direction to suit an application. The full output power rating is available regardless of airflow direction.
The four output module slots provide 19 nominal output voltage options from 3.3 to 60V DC. Outputs are derived from one of four base, digitally controlled, module designs offering a wide voltage adjustment range, claims the company. As well as offering flexibility, users can adjust the supply to meet an end application. It also minimises individual inventory items and supports fast turnaround delivery of configured products, adds the company.
There is support for both analogue and digital control. The analogue signals include AC OK (global), DC OK (global and local module), remote on/off (global and local), voltage adjustment, remote sense and current share controls. The digital functions use a subset of the PMBus command protocol, with digital equivalents of all the analogue signals and controls, together with over-voltage, over-temperature, over-current and fan-fail warning functions.
A GUI can be used to control and configure the supply, via an I2C interface using the PMBus commands, to refine configuration during the system development phase, if needed.
Approvals include medical and IT safety approval standards IEC/EN/ANSI/AAMI 60601-1 and IEC/EN/UL60950-1. The series provides 2 x MOPP according to the 3rd edition of the medical safety standard. It is supplied with a three-year warranty.
