AC/DC power supplies offer two mounting choices
Littleton, Mass. — XP Power has introduced the ECL series of ultra-compact, low-power AC/DC power supplies. Available in two series, the 10-W ECL10 and the 15-W ECL15 are offered in three mechanical formats: open frame PCB mount, encapsulated PCB mount and open frame chassis mount. The units target low-cost, low-power applications where available space is at a premium.

The ECL10 open frame PCB mount unit measures 1.0 x 2.0 x 0.9 inches (25.4 x 50.8 x 22.8 mm), and offers a power density of 5.6 W per cubic inch. The company believes it is the industry's smallest 10-W AC/DC power supply in this type of package.

Both the ECL10 and ECL15 AC/DC power supplies are available with single output voltages of 3.3, 5, 9, 12, 15, 24 and 48 Vdc. Full power is supplied across the whole input voltage range of 85 to 264 Vac or 120 to 370 Vdc. The units operate across a wide temperature range of 20°C to +70°C, with derating above 50°C.

The units operate at full power with convection cooling so there is no need for additional thermal components or fan cooling. The peak load capability of the supplies is 130% of nominal, for up to 30 seconds. This feature means that, for applications that require higher peak power, the ECL series can be specified in place of higher power, more expensive devices.

The ECL10 and ECL15 are suitable for use in both Class I and II isolation systems, meaning they can be used with or without an earth connection. This makes it ideal for portable equipment or where a reliable ground source is not available. External filtering is not required since the power supplies already meet EN55022, level B for conducted and radiated EMC.

Pricing: As low as $19.50 for 1,000 units.
