3.2.22. +/- DC INPUT Terminal.
The positive (LOAD +) and negative (LOAD -) power input terminals are clearly
Marked. DO NOT confuse them with the smaller SENSE terminals.
Please ensure that the voltage and current rating of the DUT do not exceed the
Maximum rating of the 3350F Electronic load being used. Please also check the
output polarity of the DUT prior to connection and testing.
The negative load terminal should be connected to ground if testing a positive
Output power supply. This is normally achieved when the negative output of the
Power supply is grounded.
Similarly if a power supply with a negative output is to be tested then the positive
Load terminal should be grounded. This is normally achieved when the positive
Output of the power supply under test is grounded.
3.2.23. V-sense input terminal
The V-sense terminals can be used to compensate for a voltage drop in the load
Lines between the power supply and the 3350F series Electronic Load. This is a
useful feature useful when the load current is relatively high.
If remote sense is required the V-sense terminals are connected to the appropriate
Positive and negative terminals of the power supply as shown in Fig 3-3.
