Remote shutdown ! 100kHz switching frequency ! Continuous short circuit protection ! Six-sided shielding T he 18-Watt TA 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, remote on/ off control, logic compatible with CMOS or open collector TTL, short circuit protection with auto restart, overvoltage protection, and an operating temperature range of -25C to +71C with no derating. Units are packaged in a sixsided continuous shielded case for EMI/RFI protection and measure 2.5" x 3.0" x 0.83". 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 TA Series Ordering Information Input Voltage Range Output Voltage Output Current Model Number 9-36 Vdc 20-72 Vdc 5 Vdc 5 Vdc 3500mA 3500mA TA11-350-18 TA11-350-48 9-36 Vdc 20-72 Vdc 12 Vdc 12 Vdc 1500mA 1500mA TA12-150-18 TA12-150-48 9-36 Vdc 20-72 Vdc 15 Vdc 15 Vdc 1200mA 1200mA TA13-120-18 TA13-120-48 9-36 Vdc 20-72 Vdc 12 Vdc 12 Vdc 750mA 750mA TA22-150-18 TA22-150-48 9-36 Vdc 20-72 Vdc 15 Vdc 15 Vdc 600mA 600mA TA23-120-18 TA23-120-48 9-36 Vdc 20-72 Vdc +5 / 12Vdc +5 / 12Vdc 2000 / 310mA 2000 / 310mA TA34-260-18 TA34-260-48 9-36 Vdc 20-72 Vdc +5 / 15Vdc +5 / 15Vdc 2000 / 260mA 2000 / 260mA TA35-250-18 TA35-250-48 Dimensions and Connections NOTES: 1.
