Installation Load Connection
connector's plastic backshell). This way, the output voltage is as programmed near
the module's output connector. Voltage drop may occur along the load lines due to
the load current and the cables resistance.
Local sensing connection is a convenient practice when using low load currents or
when the load regulation is not critical.
In remote voltage sensing connection, the +/-SENSE lines are connected to the
respective +/-VOUT lines near the load connections. This way, the output voltage is
as programmed near the load. The modules compensate for the load lines voltage
drop (up to 2V drop over the two lines together).
Remote sensing connection is a convenient practice when using high load currents
or when the load regulation is critical.
WARNING
Be careful to avoid +/-SENSE lines inverted connection. Inverted connection
may damage the corresponding module.
Open +/-SENSE lines will result in accuracy detriment of the
output voltage. Output voltage might be somewhat higher than
programmed!
It is recommended to use twisted pair wires for the +/-SENSE
lines, and to rout them closely in parallel to the +/-VOUT lines. In
noisy environments, it might be necessary to use twisted shielded
wires for the +/-SENSE lines. In this case, connect the shield to the
-VOUT line near the module's output connector, and leave the
other shield side open (Do not use the shield as the - VOUT or -
VSENSE wire).
Dual output
connector
modules
There are two load connectors in each module that provides over 40A: a main
connector (labeled M) with the output lines and the sense lines, and a secondary
connector (labeled S) with output lines only. Both connectors must be used, with
their output lines connected in parallel.
WARNING
Be careful to connect both the main and the secondary connectors, and make sure
they are in their right places. Interchanging between the connectors will leave
open sense lines!
