These Product Tours are just a structured sequence of web pages. Click the ► button to step through them.
The navigation buttons have the following functions:
|◄ takes you back to the beginning of the current tour
◄ is the same as your browser back button
▲ takes you up a level in the hierarchy
► steps forward to the next page
The drop-lists give another way of accessing the same pages
shows and hides a map of the structure of the tour with links to each page.

CPX DC Supplies: Remote sense for precision regulation
Remote voltage sense for "true" load regulation
Most laboratory power supplies quote
impressive figures for load regulation.
Unfortunately, the impedance of the
connection leads can make this a nonsense for regulation at the
load.
If the current is high, the meter will show
a significantly higher voltage than the load is actually seeing.
(for example, two 0.02 Ohm connection leads will drop 120mV at
only 3 amps).
The CPX Series has easy access remote sense
terminals - unlike many general purpose laboratory power
supplies - to ensure perfect regulation and meter precision.
Remote or Local at the flick of a switch
Research shows that engineers choose not to
use remote sense for many applications.
The CPX Series makes the choice as easy as
possible with a front mounted local/remote sense switch.
