Available exclusively from DT Electronics, N2 Power’s XL250 is the world’s smallest 250W AC/DC power supply with a footprint of 3in x 6in or 3in x 7in and a height of 1.5in, less than 1U. The open-frame switcher has a power density of up to 9.25W/in3. and is up to 88% efficient. It has a universal AC input and up to 5 single outputs between 5VDC and 48VDC as well as multi-output variants. Other features include remote on-off, remote sense, built in O-ring diodes for parallel connection in N+1 power architectures, and active power factor correction. A major feature is the low in-rush current rating, which at 12A at 240VAC is the lowest in the industry - an important factor in current share applications.

Auxiliary outputs of 10W, 5V standby and 12V 2.5A are standard on all single-output units, as well as being part of the multi-output configuration. The power supply will operate without a load and will run at up to 150W output at 50 °C with convection cooling or at full rated power with only 10CFM forced-air cooling. Under- and over-shoot are limited to less than 10% of nominal output voltage at switch-on and hold-up time is at least 22ms. The power supply delivers full output from -25 °C to +50 °C ambient, de-rating at 2.5%/°C between 50 °C and 70 °C. The XL250 has a calculated MTBF of greater than 200,000 hours and leakage current below 0.75mA. It has integral over-voltage, over-power, over-temperature and short-circuit protection. The unit has full agency approvals with respect to EMC and safety.

Custom configurations are also available, depending on the project requirements.

Prices start at approximately £75 each for 100 piece quantities.
