XP Power Announces New Series Of Single 25W Output, Low Power AC-DC Power Supplies

XP Power announced the availability of its ECL25 series of single output, low power ac-dc power supplies. Extending the current ECL product line-up of 10 and 15W units, the new 25W output family is available in chassis, PCB or encapsulated PCB mount formats.

Starting at only 3.0 x 1.4 x 1.1" (76.2 x 35.6 x 26.7mm) for the pcb mount version, the units are said to suit low power, low cost applications where board or chassis space is limited. With a power density of 5.7W per cubic inch, the company believes that the supplies offer the highest power density and are 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 48 Vdc unit is rated at 82% power efficiency. No additional heat sinking or forced airflow is required, making the supplies suitable for most operating environments. They operate at full power from -20 to +50°C and derate linearly to 50% output at +70°C. For applications where a higher peak output is required for short periods the ECL25 series is suitable. All models have a peak load capability that can provide 130% of rated output power for a maximum of 30 seconds.

The series has a Class II input, meaning that no grounding is required. This suits portable equipment designs where a reliable ground source is not always available. Input to output isolation is rated at 3,000Vac. External filtering components are not required since the power supplies already meet EN55022, level B for conducted and radiated EMC. All models carry EN, UL, CSA and CE safety approvals.

The ECL25 is priced at $27.30 each for OEM quantities.
