TEQ 300-4812WIR

The TEQ 300WIR series from Tracopower are 300W isolated high performance DC/DC converters. These converters with rugged, sealed metal case are suitable for industrial applications where often no PCB mounting is possible but module has to be mounted on a chassis. The ultra-wide 4:1 input voltage range and reverse input voltage protection make these converters also an interesting solution for battery operated systems. The TEQ 300WIR series features output voltage trimming, remote on/off, undervoltage lockout, soft start, remote ON/OFF, output current limitation, overvoltage protection and automatic recovery short circuit protection (hicc-up). Approved by IEC/EN 62368-1, IEC/EN 60950-1, UL 60950-1 and UL 508 safety standards.
