Feature Descriptions
Output Voltage Set-Point Adjustment (Trim)
(continued)
Although the output voltage can be increased by both
the remote sense and by the trim, the maximum
increase for the output voltage is not the sum of both.
The maximum increase is the larger of either the
remote sense or the trim. Consult the factory if you
need to increase the output voltage more than the
above limitation.
The amount of power delivered by the module is defined
as the voltage at the output terminals multiplied by the
output current. When using remote sense and trim, the
output voltage of the module can be increased, which at
the same output current would increase the power output
of the module. Care should be taken to ensure that the
maximum output power of the module remains at or
below the maximum rated power.

Output Overvoltage Protection
The output overvoltage clamp consists of control cir-
cuitry, independent of the primary regulation loop, that
monitors the voltage on the output terminals. The con-
trol loop of the clamp has a higher voltage set point
than the primary loop (see Feature Specifications
table). This provides a redundant voltage control that
reduces the risk of output overvoltage.
