TPP450 (Enclosed package)

• Thermally efficient design allows fanless operation up to 320W at full load
• Variable fan speed controller allows quiet operation

TPP450A (Open-frame package)

• Thermally efficient design allows convection cooled operation up to 320W at full load
• An integrated variable fan speed controller allows for an easy use of an external fan

The TPP 450 Series of 450 Watt AC/DC power supplies feature a reinforced double I/O isolation system according to latest medical safety standards. The earth leakage current is below 100 μA what makes the units suitable for BF (body floating) applications. The excellent efficiency of up to 94% allows a high power density for the standard 3x5x1.58 inch packaging format.  

The forced air cooling full load operating temperature range is –40C to +50°C while it goes up to 85°C with 50% load derating. Natural convection cooled power is 320W up to +50°C and 150W at +85°C. Thus you can power your medical device in a quiet and hygienic way as you don’t need to run a fan to cool down the power supply. They come with an active power factor correction and the EMC characteristic is dedicated for applications in industrial and domestic fields. High reliability is provided by use of industrial quality grade components and an excellent thermal management. It makes the products an ideal solution for medical devices and for demanding safety and space critical applications.
