= The max. input range of 16 to 50 VDC is specified for 250 mS (Per
MIL-STD-704D).
= Total output power should not exceed 16W. The load on
any auxiliary output should not exceed 500 mA.
= Outputs are adjustable on single and dual output units only.
= Voltage balance is measured with balanced loads applied.
= Transient response is measured on the primary output for a 50%
load change (50% load to full load).
= Efficiency is specified at nominal input line and full load.
= These converters have a thermal resistance of 2.1
o
C/W (Internally
dissipated). The internal thermal protection circuits are trigged if
the case temperature exceeds 95
o
C. Maintaining the module case
temp. below 95
o
C can be accomplished by mounting a low
thermal resistance heat sink (with vertically orientated fins) to the
case with a thermally conductive compond. This will significantly
increase heat transfer from the module to the ambient. Forced
convection cooling can also be used. The amount of cooling will
depend upon the flow of air in linear feer per minute (LFM) over
the module.
