Single-output supplies come with small claims

Ultracompact low-power AC/DC power supplies are billed as the world's smallest 10 and 15W-rated devices.

Available now from XP Power, the ECL series of ultracompact low-power AC/DC power supplies are billed as the world's smallest 10 and 15W-rated devices.

Both ratings are available in three mechanical formats: open frame PCB mount, encapsulated PCB mount, and open frame chassis mount.

The ECL10 open frame PCB mount unit measures just 25.4 x 50.8 x 22.8mm, and has a power density of 5.6W/in3.

The ECL series is ideal for helping manufacturers meet the specifications for compact, portable or fixed end products.

In particular, the units are perfect for low cost, low power applications where the available space is at a premium.

The ECL10 and ECL15 are available with single output voltages of 3.3, 5, 9, 12, 15, 24 and 48V DC.

Full power is supplied across the whole input voltage range of 85-264V AC or 120-370V DC.

The units operate across a wide range of temperatures, from 20 to +70C, with derating above 50C.

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.
