LOAD CONNECTION USING REMOTE SENSING
Figure 2-13 shows a typical configuration using remote sensing.
Use #22 AWG wire, twisted
pair for remote sense connections. Table 2-5 shows typical load wire length, AWG wire size
and load current required for a voltage drop of less than 1V. Table 1-1 lists the maximum
voltage drop compensation for each model that will allow voltage measured at the load to
be the same as the voltage shown on the front panel display.
CAUTION: CONNECT +S ONLY TO + AND –S ONLY TO –. CONNECTING +S TO –S, +V
TO –S, OR –V TO +S WILL DAMAGE THE UNIT.
