TEC 3UI DC-DC Converters

TRACO Power TEC 3UI DC-DC Converters are designed to replace the existing 2:1 and 4:1 input converters. These cost-efficient, isolated converters have an ultra-wide 9VDC to 75VDC input voltage range and offer up to 81% typical efficiency. The TEC 3UI DC-DC converters are equipped with short circuit protection, under voltage lockout, over-current limitation, and feature remote control functions. These converters are available in single- and dual-output models in a compact SIP-8 plastic case. The TEC 3UI series are safety approved to IEC/EN/UL 62368-1 standards and are rated for full load operation from -40°C to 80°C. These DC-DC converters are suitable for space-constrained and industrial applications.
