Highly qualified power supplies offer extended temperature ranges

Traco Power has released their TPP 15A-D and TPP 30A-D series of medical and industrial approved 15W and 30W PCB-mount, open-frame power supplies measuring only 1.5" x 1" x 0.8” (15W) or 2.74" x 1.36" x 0.95” (30W) highlighting an extended operating temperature range of -40C to +85C and safety qualified for industrial and medical applications as well as smart homes and buildings for IoT challenges. The families provide eight single output models ranging 3.3-48Vout. High efficiency up to 91.5% and industrial grade components allow an extended temperature range of -40C to +85C, with outstanding full-load convection operation up to 60C ~ 75C (depending on model) and a working altitude to 5000m. These models offer double reinforced I/O isolation, less than 75µA earth leakage current and Class I/Class II protection. Safety certifications include IEC/EN/ES 60601-1 3rd edition for 2xMOPP and Type BF medical applications; UL/IEC/EN 60950-1 and UL/IEC/EN 62368-1 for ITE/Industrial applications; and IEC/EN 61558 and IEC/EN 60335-1 for household appliances. All models are EMC compliant to EN 55032 class B and EN 60601-1-2 4th Edition. Reliability of >3 million hours per MIL-HDBK-217F @ 25C is further demonstrated with compliance to IEC 60068-2-6 (Vibration), IEC 60068-2-27 (Shock) and MIL-STD-810F (Thermal Shock).
