SPECIFIATION NOTES

1 = The max. input range of 16 to 50 VDC is specified for 250 mS (Per

MIL-STD-704D).

2 = Total output power should not exceed 16W. The load on

any auxiliary output should not exceed 500 mA.

3 = Outputs are adjustable on single and dual output units only.

4 = Voltage balance is measured with balanced loads applied.

5 = Transient response is measured on the primary output for a 50%

load change (50% load to full load).

6 = Efficiency is specified at nominal input line and full load.

7 = These converters have a thermal resistance of 2.1 oC/W (Internally

dissipated). The internal thermal protection circuits are trigged if

the case temperature exceeds 95oC. Maintaining the module case

temp. below 95oC 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.
