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.
Standard features include remote sensing, output trim, and
remote on/off. Threaded-through holes are provided to allow
easy mounting or to add a heat sink for extended temperature
use.
