Input Terminal Connector; Local Sense Configuration - Ametek Amrel PLA Series Operation Manual

INPUT TERMINAL CONNECTOR

WARNING
JJJJJJ
There is a shock hazard at the load when using an electronic load with a rated output greater than 40V. To
protect personnel against contact with hazardous voltages, ensure that the load, including connections, has no live
parts, which are accessible. Also ensure that the insulation rating of the source wiring and circuitry is greater than
or equal to the maximum output voltage of the electronic lo ad.
CAUTION
When making connections to the bus bars. Ensure that each terminal's mounting hardware and wiring assembly
are placed to avoid touching the other terminal and shorting the electronic load input. Heavy connecting cables
must have some form of strain relief to avoid loosening the connections or bending the bus bars.

LOCAL SENSE CONFIGURATION

When the Electronic Load is strapped for local sensing, an unavoidable voltage drop is incurred in the load leads and this
adds to the load regulation. Hence, local sensing is usually used in applications where the lead lengths are relatively short,
or loa d regu lation is not critical.
CONTROL→REMOTE SENSE → LOCAL and pressing enter button to confirm.
To meet safety requirement, load wire size should be large enough to carry electric current of the source to the Electronic
Load without overheating. Stranded, copper wires are recommended. The wires should be large enough to limit the
voltage drop to less than 1V per lead. Refer to Table 2.4 for proper wire size selection. Input wire connections are made
to the "+" and "-" terminals on the rear panel of the Load.
USE THE LARGEST GAUGE,
LOWEST INDUCTANCE AND
SHORTEST LENGTH POSSIBLE
