The TEQ 300WIR Series is a family of isolated high performance DC/DC con-
verter modules with ultra-wide 4:1 input voltage ranges which come in a
rugged, sealed metal case.
These converters are suitable for a wide range of applications, but the product
is designed particularly also for industrial applications where often no PCB
mounting is possible but the module has to be mounted on a chassis. A very
high efficiency and the overall heatsink construction allows an operating tem-
perature up to +55°C with natural convection cooling without power derating
and up to +80°C with power derating. Further features include output voltage
trimming, Remote On/Off and under voltage lockout. The ultra wide input volt-
age range and reverse input voltage protection make these converters also an
interesting solution for battery operated systems.
