TRACO Power TPP 450A-M Features & Benefits

TRACO Power’s TPP 450A series is a 3x5 inch open frame power supply for medical devices and demanding space critical applications. The TPP 450A series has a high power density and is rated for up to 450 watts of output power with only 21 CFM external forced air. When convection cooled, the TPP 450A-M has an output rating of 320 watts without derating up to 50 degrees Celcius. The TPP 450A-M series has an AC input range of 85~264Vac which is then converted into 12V, 15V, 24V, 36V or 48V DC outputs. The TPP 450A series is extremely efficient, reaching up to 94% efficiency.


Approved for both medical and industrial applications, the TPP 450A series is a versatile 450 watt 3x5 power supply solution. The TPP 450A is medically approved for ANSI/AAMI ES 60601-1: 2005(R) and IEC/EN 60601-1 3rd edition, 2xMOPP. It is suitable for BF applications with less than 100uA leakage current where the patient could come in contact with the output of the power supply. The TPP 450A is also in compliance with latest EMC emissions specification: IEC 60601-1-2 4th edition. Furthermore, TRACO Power TPP 450A series maintains the latest hazard based standard, UL 62368-1 safety approval. The UL 62368-1 is the agency safety approval for audio/video and information/communication technology equipment. The new UL 62368-1 standard is scheduled to globally replace UL 60950-1 by the end of 2019.


Additional features of the TRACO Power TPP 450A series include: 5V standby output, 12V aux output, remote On/Off, power good signal, adjustable output voltage, built-in Power Factor Correction, operation up to 5000m altitude and an integrated variable fan speed controller for convenient use of an external cooling fan.


The TPP 450A-M series is also available with a built-in fan and chassis version.
