TEC 3-2421UI

TEC 3-2421UI is a TEC 3UI series 3W, isolated DC/DC converter with ultra-wide input range. This new converter generation is designed to seamlessly replace and offer an alternative to existing 2:1 and 4:1 input converter, ensuring no compromise on performance or cost-effectiveness. With an input voltage ranging from 9 to 75VDC, the TEC 3UI covers a variety of standard bus voltages, minimizing the need for multiple model variants in an application. It is equipped with short circuit protection, over current limitation, under voltage lockout and feature remote control functions. The converter operates reliably up to a maximum temperature of +90°C, with an approved operating temperature range of -40°C to +80°C according to IEC/EN/UL 62368-1 and can operate at altitudes up to 5000 meters. The compact SIP8 plastic case makes the TEC 3UI series ideal for space-constrained applications.
