Description
The 75 watt single HE series DC/DC converters provide
precisely regulated dc outputs. All outputs are fully isolated
from the inputs, allowing the output to be used with positive or
negative polarity and various grounding options. The HE
series meets the most rigorous requirements in an industry
standard case size for industrial process control and telecom
applications.

(4) Optimum performance is obtained when this power supply is
operated within the minimum to maximum load specifications.
No damage to module will occur, when the output is operated at
less than minimum load, but the output voltage may contain a
low frequency component that may exceed output noise
specifications.

(8) Noise is measured per the CALEX Application Notes. Output
noise is measured with a 10µF tantalum capacitor in parallel with
a 0.1 µF ceramic capacitor connected across the output to CMN.
Measurement bandwidth is 0-20 MHz.
Output Voltage Remote Sensing
(9) When an external On/Off switch is used, such as open collector
switch, logic high requires the switch to be high-impedance.
Switch leakage currents greater than 10 uA may be sufficient to
trigger the ON/Off to the logic-low state.

there is a problem, you can make following estimations and then
leave some margins.
