In summary, the TPP 450 is an ideal solution for space limited applications that require maximum power in a small space regardless of the end market. The product is designed to help engineers meet both thermal and compliance challenges. The product family supports thermally challenged industrial applications where the operating ambient temperature within the system can exceed +50°C, having an extended operating temperature range and usable power up to +85°C for the open frame version and +80°C for the enclosed with fan version. Medical requirements often require a low level of audible fan noise, whether external or internal to the power supply. The TPP 450 open frame models have both conduction and convection ratings to support low noise environments where fan noise is not tolerated. The TPP 450 has an integrated 12 V fan output with variable speed control to minimize fan noise when using system provided fans or the enclosed with fan model.
