THN 20-2411WI-A1 TRACO Power

DC/DC Converter THN 20WI Series, 20 Watt Ultra compact size: 1.0 x 1.0 x 0.4 Shielded metal casing with isolated baseplate Ultrawide 4:1 input voltage ranges Very high efficiency up to 90% Output voltage adjustable UL 62368-1 IEC 62368-1 Remote On/Off control The THN 20WI series models are high performance DC/DC converters. They achieve 20 W output power and come in a small size metal casing (1.0 x 1.0 Operating temp. range 40C to +75C x 0.4 ). The models feature an ultra-wide 4:1 input voltage range while the out- and up to 85 C with heat-sink put voltages are precisely regulated even under no load conditions. Highest ef- I/O isolation voltage 1600 VDC ficiency of up to 90% makes this product very reliable and applicable in tem- perature ranges of up to 85C. The low no-load input current characteristics Input filter meets EN 55032 class A and the remote On/Off control make these converters an ideal solution for bat- without external components tery operated systems. Typical applications are in mobile equipment, instru- 3-year product warranty mentation, distributed power architectures in communication and industrial electronics and everywhere where space on the PCB is critical.
