Power Sources Unlimited announces the N2Power XL275 Series of ultra small, highly efficient (up to 90%) ac/dc power supplies which pack 275W of power into an industry leading 12.22W/cubic inch power density, fitting easily into industry standard 1U OEM applications or any application where space is critical.

The XL275 Series features a universal 90-264VAC input with active PFC. Four initial models provide single outputs from 12VDC to 56VDC, along with a secondary 12VDC/1A output, and a 5VDC/1A standby output. All outputs may be paralleled.

The XL275’s operation is ensured via digital microprocessor control to monitor output voltage, output current, auxiliary output voltages, ambient temperature and cooling fan speed. Comprehensive protection circuitry and remote on/off are also standard features of the power supply, with I2C based PMBus™ capability as an option.

Worldwide safety compliance to Information Technology Equipment safety standards, RoHS compliance, and an MTBF in excess of >200,000 hours make the XL275 Series ideal for any application, where reliability is of utmost importance.
