DC/DC Converter THN 20 Series, 20 Watt Smallest encapsulated 20 W Converter Ultra compact size: 1.0 x 1.0 x 0.4 Shielded metal case with isolated baseplate Wide 2:1 input voltage ranges Very high efficiency up to 90% UL 62368-1 IEC 62368-1 Output voltage adjustable The THN 20 series is the latest generation of high performance DC/DC con- Remote On/Off control verter modules with highest power density. The product achieves 20 W output power while it comes in a metal case with dimensions of only 1.0 x 1.0 x Operating temp. range 40C to +75C 0.4 . All models have a wide 2:1 input voltage range and precisely regulated and up to 85 C with heat-sink output voltages, even under no load conditions. Highest efficiency of up to I/O isolation voltage 1500 VDC 90% makes this product very reliable and applicable in temperature ranges of up to 75C or 85C with optional mounted heat sink. Together with low input Input filter meets EN 55022 class A current characteristics at minimal load and remote On/Off control these con- without external components verters are the ideal solution for battery-operated systems. Typical applications 3-year product warranty are in mobile equipment, instrumentation, distributed power architectures in communication and industrial electronics and everywhere where space on the PCB is critical.
