Models
The TEQ-160WIR 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, sealed metal case.
These converters are suitable for a wide range of applications,
but the product is designed particularly also for industrial appli-
cations 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 temperature
up to +75°C with natural convection cooling without power derating
and up to +90ºC with power derating. Further features include output
voltage trimming, Remote On/Off and under voltage lockout. The
very wide input voltage range and reverse input voltage protection
make these converters also an interesting solution for battery operated
systems.
