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 remote control functions. The series is available in single- and dual-output models in a compact SIP-8 plastic case that is safety-approved to IEC/EN/UL 62368-1 standards and rated for full-load operation from -40°C to +80°C. TRACO Power TEC 3UI DC-DC Converters are suitable for space-constrained and industrial applications.
