CCR750 320W-750W AC-DC Power Supplies

Introduction

XP Power’s CCR750 series is an AC-DC power-supply range intended for medical and industrial equipment. Its technically notable feature is a common baseplate-cooled design that supports several thermal-management approaches: 320 W with convection cooling, 600 W with conduction cooling, or up to 750 W with fan cooling. This allows system designers to select a cooling strategy appropriate to the available airflow, enclosure design, and power requirement.

What it does

The CCR750 converts AC input power to regulated DC output options spanning 12.0 V to 54.0 V. Depending on the selected output voltage and cooling method, the series supports output currents from 5.92 A to 62.50 A.

Efficiency is specified from 92.0% to 94.0%, helping reduce the heat that must be managed at higher output powers. The supplies use a low-profile format measuring 154.8 mm × 83.5 mm × 25.4 mm, with a stated weight of 600 g.

For equipment with medical safety considerations, the series specifies 4000 VAC minimum input-to-output isolation with 2x MOPP, along with 1x MOPP ratings for input-to-ground and output-to-ground isolation. Maximum patient leakage current is specified as 90 μA, and the series is described as body floating (BF) rated. It also states Class B conducted and radiated emissions characteristics.

Applications

Potential applications based on the stated medical, industrial, power, and cooling characteristics include:

• Medical equipment requiring BF-rated power architecture and 2x MOPP input-to-output isolation
• Industrial equipment with a baseplate or chassis available for conduction cooling
• Systems designed for quiet or reduced-airflow operation at up to 320 W using convection cooling
• Higher-power equipment able to accommodate fan cooling for outputs up to 750 W
• Multi-voltage product platforms requiring DC outputs between 12.0 V and 54.0 V

Design considerations

Thermal integration is a primary consideration for the CCR750. Output capability changes substantially with the cooling method: convection-cooled operation is specified to 320 W, conduction-cooled operation to 600 W, and fan-cooled operation to 750 W. Designs should therefore account for the intended baseplate, conductive path, or fan arrangement rather than treating the maximum rating as independent of cooling conditions.

The 25.4 mm profile can assist where vertical space is limited, but the overall 154.8 mm × 83.5 mm footprint and 600 g weight remain relevant to mechanical layout and mounting design. Output voltage selection also affects available output current, so the required load voltage and current should be considered together.

For medical isolation architectures, the stated 2x MOPP input-to-output isolation and the separate 1x MOPP input-to-ground and output-to-ground ratings should be evaluated in the context of the complete equipment insulation system.
