7 LAYOUT AND CONNECTION OF THE ARE28XXS-D
It is recommended to connect the input power and the load to the ARE28XXS-D converter
with as short wires as possible for best results. It is recommended that TEFLON coated
stranded copper wires of correct AWG gauge be employed to meet current capacity and
insulation requirements for high reliability. Input Positive and Return wires can be twisted
and likewise output Positive and Return wires can be twisted. If shielded wires are
employed, shields can be connected to input return for input wires. Likewise, shield can be
connected to output return for connections to load. The case of the ARE28XXS-D converter
can be grounded (i.e. earthed).
8 CONCLUSION
The Rad Hard ARE28XXS-D converters have been well designed and thoroughly tested
products destined for use on satellites and variety of critical space missions, where size and
weight are real constraints, but reliability and long life can’t be compromised. This
Application Note is prepared with objectives to help designers and product planners for such
critical missions by providing insight into four aspects of their use:
1. Systematic explanation of the overload and short circuit behavior
2. Remote Sense Operation
3. Enhancing Output filtering by use of an external filter.
4. Checking and ensuring full stable performance while using external filters in
conjunction with Remote Sense facility.
