Safety and Installation Instruction
Fusing Consideration
Caution: This power module is not internally fused. An input line fuse must always be used.
This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone
operation to an integrated part of sophisticated power architecture. To maximum exibility, internal fusing is not
included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety
agencies require a normal-blow fuse in 5Vin with maximum rating of 1000mA, in 12Vin with maximum rating of
500mA, in 24Vin with maximum rating of 200mA. Based on the information provided in this data sheet on Inrush
energy and maximum dc input current; the same type of fuse with lower rating can be used. Refer to the fuse
manufacturer’s data for further information.
MTBF and Reliability
The MTBF of TES 2M series of DC/DC converters has been calculated using
