The series now offers Protection Class II models (TPP 450BA-M Open-Frame Models and TPP 450B-M Enclosed with Fan Models), designed for non-stationary requirements where connection to ground is not possible.
Key approvals on the original series remain on the expanded 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 with low leakage current (<100µA) for a 2 x MOPP rating and BF compliance. High efficiency up to 94% supports a convection-cooled operation up to 320 W at +50°C and 450W operation at +65°C with 20cfm airflow.
Additional features include 5 VDC standby; 12 VDC variable-speed fan output; remote on/off and power good signal. Industrial grade components and advanced thermal management offer high reliability. Potential applications include portable medical equipment, home healthcare devices and any space-limited application where a superior power rating is required.
