450W medical power supplies in a 3”x5”package
The TPP450 (Enclosed package) and TPP450A (Open-frame package) convection/conduction cooled medical AC/DC power supplies feature a reinforced double I/O isolation system according to latest medical safety standards.

The earth leakage current is below 100μA 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 -40 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.  The units 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. The power supplies deliver a 5VDC standby output, 12VDC auxiliary output and allows remote On/Off operation, with power good signal. An integrated variable fan speed controller allows for an easy use of an external fan.
