REMOTE SENSING (REMOTE ERROR SENSING)

A means whereby a constant voltage power supply monitors and regulates its output voltage directly at the load terminals (instead of the power supply output terminals). Two low current sensing leads are connected between the load terminals and special sensing terminals located on the power supply, permitting the power supply output voltage to compensate for IR drops in the load leads (up to a specified limit).

RESOLUTION

The smallest change in output voltage or current that can be obtained using the front panel controls.

SOURCE EFFECT (LINE REGULATION)

Formerly known as line regulation, source effect is the change in the steady-state value of the dc output voltage (of a CV supply) or current (of a CC supply) due to a specified change in the source (ac line) voltage, with all other influence quantities maintained constant. Source effect is usually measured after a "complete" change in the ac line voltage; from low line to high line or vice-versa.
