The harsh environment often found in railway or industrial applications is a real challenge for electronics, especially for power supplies. Wide temperature range, vibrations, wide input voltage variations require high quality power supplies to meet reliability requirements.

The  TEQ-40WIR converters are suitable for a wide range of applications but the product is designed particularly for industrial applications where it happens quite often that no PCB mounting is possible but the module has to be mounted on a chassis.

A very high efficiency along with the heatsink construction allow the operating temperature of up to +83°C with natural convection cooling without power derating and up to +92°C with power derating.
Further features include under voltage lockout, over-temperature protection and short circuit protection.
