THN 20-2412WI

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