Load Considerations - Agilent Technologies N8700 User Manual

NOTE

Load Considerations

Multiple Loads
Series N8700 User's Guide
If the power supply is operated with remote sensing and either the positive or
negative load wire is not connected, an internal protection circuit will activate
and shut down the power supply. To resume operation, turn the power supply
off, connect the open load wire, and turn on the power supply.
The following figure shows multiple loads connected to one power
supply. Each load should be connected to the power supply's output
terminals using separate pairs of wires. It is recommended that each
pair of wires will be as short as possible and twisted or shielded to
minimize noise pick-up and radiation. The sense wires should be
connected to the power supply output terminals or to the load with
the most critical load regulation requirement.

If remotely located distribution terminals are used, as shown in the
following figure, the power supply output terminals should be
connected to the remote distribution terminals by a pair of twisted
and/or shielded wires. Connect each load to the distribution
terminals separately. Remote voltage sensing is recommended under
these circumstances. Sense either at the remote distribution
terminals or, if one load is more sensitive than the others, directly at
the critical load.
