Continuous short circuit protection ! Six-sided shielding T he 18-Watt TUC/TUM Series operates over an ultra wide input range of 9-36 Vdc or 20-72 Vdc. Efficiencies of 77% are typical over varying load conditions of 25% to 100%. Additional features include input reverse polarity protection, short circuit protection with auto restart, overvoltage protection, and an operating temperature range of -25C to +71C with no derating. Applications These units are ideally suited for telecommunications and applications having a widely varying input voltage such as automotive test equipment, process control, minicomputers, and geosurvey equipment. 1 TUM/TUC Series Ordering Information Input Voltage Range Output Voltage Output Current Model Number Model Number 9-36 Vdc 20-72 Vdc 5 Vdc 5 Vdc 3500mA 3500mA TUM11-350-18 TUM11-350-48 TUC11-350-18 TUC11-350-48 9-36 Vdc 20-72 Vdc 12 Vdc 12 Vdc 1500mA 1500mA TUM12-150-18 TUM12-150-48 TUC12-150-18 TUC12-150-48 9-36 Vdc 20-72 Vdc 15 Vdc 15 Vdc 1200mA 1200mA TUM13-120-18 TUM13-120-48 TUC13-120-18 TUC13-120-48 Dimensions and Connections PIN CONNECTIONS Pin / Terminal 1. +Input 2. -Input 3. + Output 4.
