4.2.1.2.1 V_SNS+ and V_SNS-
The distance of the load and the module can create a voltage drop on the wires. To compensate for the
voltage drops on the wire, remote sense is employed.
The module has a positive return, V_SNS+ J2 Pin 1, and a negative return, V_SNS- J2 Pin 8, remotes sense to
compensate for ground drops and line drops respectively. Remote sense will be able to regulate out a
maximum of 200mV drop on each sense line. It is recommended for user to connect the remote sense either
on the load side or to the output terminals of the modules. The connection of the remote sense signal
determines the point at which the voltage will regulate. Remote sense is required to meet the regulation
specification of the module. Remote sense is required during voltage source configuration.
The module will protect itself if the polarity is incorrectly connected between the V_SNS+ and V_SNS- to
module’s output positive and negative terminal. It is recommended to use twisted and equal length wires for
V_SNS+ and V_SNS- for noise immunity.
For parallel module output operation, all module V_SNS+ should be star connected and all
module V_SNS- should be star connected as shown by examples in Figure 4-7. Star connection is
recommended to reduce the introduction of DC offset and noise to the signals.
