THD 12-4811 TRACO Power

DC/DC Converter THD 12 Series, 12 Watt Wide 2:1 input range Very high efficiency up to 88% I/O isolation 1500V Input filter meets EN 55032, class A Remote On/Off UL 62368-1 IEC 62368-1 Under voltage lock-out circuit The THD 12 series is a range of high performance, isolated 12W DC/DC con- Shielded metal case with insulated verters. They come in a low profile, DIP-24 package with standard industry Baseplate pin-out. Overload and overvoltage protection as well as remote On/Off are in- Continuous short-circuit protection cluded as standard. Built-in filters for both input and output minimizes the need of external filtering. Full SMD-design with exclusive use of ceramic capacitors Operating temp. range 40C to +85C guarantees a high reliability and long product lifetime. Typical applications for (with derating) these converters are industrial electronics, instrumentation, data communica- 3-year product warranty tion systems and battery operated equipment with limited space available on the PCB Models Order Code Input Voltage Output 1 Output 2 Efficiency Range Vnom Imax Vnom Imax typ.
