XP Power has the ECL25 series of single output, ultra compact, low power AC-DC power supplies.

Extending the current ECL product line-up of 10W and 15W units, the 25W output family is available in chassis, PCB or encapsulated PCB mount formats.

Starting at only 76.2x35.6x26.7mm for the PCB mount version.

With a power density of 5.7W per cubic inch, the supplies are believed to offer the highest power density and be the smallest of any similar 25-30W products on the market.

The ECL25 series consists of 21 single output models across the three formats providing output voltages of 3.3, 5, 9, 12, 15, 24 or 48Vdc.

The 48Vdc unit is rated at 82% power efficiency. No additional heat sinking or forced airflow is required, making the supplies ideal for most operating environments. They operate at full power from -20 to +50 degrees C and derate linearly to 50% output at +70 degrees C.

For applications where a higher peak output is required for short periods the supplier offers the ECL25 series. All models have a peak load capability that can provide 130% of rated output power for a maximum of 30 seconds.
