DC/DC Converter THD 12WI Series, 12 Watt Ultra-wide 4:1 input range Very high efficiency up to 85% I/O isolation 1500V Input filter meets EN 55032, class A without ext. Components Remote On/Off UL 62368-1 IEC 62368-1 Under voltage lock-out circuit The THD 12WI series is a range of high performance, isolated 12W DC/DC converter modules featuring ultra wide 4:1 input voltage ranges in a DIP-24 Shielded metal case with insulated package with industry-standard footprint. Overload and overvoltage protection Baseplate as well as remote On/Off are included as standard. Built-in filters for both input Continuous short-circuit protection and output minimizes the need of external filtering. Full SMD-design with exclu- sive use of ceramic capacitors guarantees a high reliability and long product Operating temp. range 40C to +85C lifetime. Typical applications for these converters are industrial electronics, in- 3-year product warranty strumentation, data communication 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.
