Traco Power launched its TPP 450 series two years ago, and the series now offers a major expansion with Protection Class II models (TPP 450BA-M Open-Frame Models and TPP 450B-M Enclosed with Fan Models). These products are well suited for non-stationary requirements where connection to ground is not possible.

Key approvals on the original series remain on the expanded the class II versions, including medical IEC/EN/ES 60601-1 and industrial IEC/EN/UL 62368-1 safety approval. Features for the medical market include a double, reinforced 4000 VAC I/O isolation system low leakage current (<100µA) for a two MOPP rating and BF compliance.

A high efficiency up to 94% supports a convection cooled operation up to 320W at +50°C and 450W operation at +65°C with 20cfm airflow. Additional features include 5VDC standby; 12 VDC variable speed fan output; Remote On/Off and Power Good Signal.

Industrial grade components and advanced thermal management ensure high reliability and the TPP 450 series is backed by a five-year warranty. Potential applications include portable medical equipment, home health care devices and any space limited application where a superior power rating is required.
