Low-profile AC/DC power supplies offer convection for medical and industrial applications

XP Power today announces a new series of low-profile 550W AC-DC power supplies rated for convection, conduction, and forced-air cooling. Approved for use in medical and industrial applications, the new PSUs are ideal for a wide range of applications, including sealed enclosure environments.

In the medical arena, CCP550 units will be found in various medical devices, including ventilators, patient monitors, imaging systems, and laboratory equipment. Industrial applications include test equipment, instrumentation, process control, industrial printing, and UV curing. They are also suited for factory automation, audio/video, and IoT equipment.

The series comprises six different single-rail outputs covering 12V, 15V, 18V, 24V, 36V, and 48VDC. All units, excluding the 15V model, include a 12V, 0.5A fan output, and a 5V/2A standby output and remote on/off capability are offered as an option.

The double-decker aluminium substrate baseplate construction, conduction-cooled power magnetics, and high efficiency ZVS topology combine to ensure high-efficiency and exceptional thermal performance. As a result, operation up to 300W is possible with convection cooling, and 400W is attainable with conduction cooling, allowing operation in sealed environments, silent running, and high levels of reliability.

When used with forced air of 20CFM, CCP550 units offer the full 550W output, providing excellent levels of power density in their low profile (37.5mm [1.48”]), 127.0mm x 76.2mm [5” x 3”] footprint.

These devices are approved for medical applications to IEC60601-1 Ed.3 with 2 x MOPP from primary to secondary and 1 x MOPP from primary to earth and secondary to earth. With low earth and patient leakage currents, they are ideal for BF patient contact medical devices.

A wide input voltage range (80-264VAC) ensures suitability for global usage, including home healthcare applications. Additionally, CCP550 devices can operate in ambient temperatures as high as +70C and as low as -30C. When the main output is inhibited, the units draw less than 0.5W, ensuring they meet challenging energy efficiency requirements.

The series is an easy-to-integrate, high-power density, high-efficiency solution for a wide range of fan-less and fan-cooled applications, including medical devices, industrial electronics, and test and measurement. Sealed, semi-sealed, and another high IP-rating usage is supported with the ability to operate when conduction-cooled.
