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.
