The TEQ-20WIR Series is a family of isolated high performance dc-dc converter
modules with ultra-wide 4:1 input voltage ranges which come in a rugged 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 heatsink construction allows an operating temperature
up to +83°C with natural convection cooling without power derating and up to
+93ºC with power derating. Further features include under voltage lockout, over
temperature protection and short circuit protection.
