XP Power plc today announced the CCL400 series of convection-cooled 400-Watt ac-dc power supplies. With a typical efficiency up to 94% and a flat efficiency curve over virtually the entire load range, the CCL400 does not require any forced air cooling. With little heat generated due to the high efficiency, the components within the CCL400 run at lower temperatures, leading to increased reliability and service life. The CCL400 can continuously deliver the full 400W output with convection cooling over the wide temperature range from -40 to +50 degrees C and across almost the entire input voltage range.
The CCL400 can also be conduction cooled, enabling the full 400W across the entire input range and up to +70 degrees C ambient temperature. Measuring 3.95 x 7.00 x 1.57 inches (100.3 x 177.8 x 39.9 mm) the CCL400 complies with the standard 1U chassis mount format. An optional enclosing cover is available to order.

Typical applications for the CCL400 include medical systems such as life support, imaging and blood processing equipment. In particular, since no cooling fans are used, the units are ideal for medical systems that stipulate low audible noise specifications. The series also suit use in a wide range of industrial and technology solutions that require a very high power density from a convection or conduction cooled power supply. The CCL400 series is priced at $206.70 for 500 pcs and comes with a 3 year warranty.
