SLTS261B – MAY 2006 – REVISED NOVEMBER 2007
+VI: The positive input for the module with respect to –VI. When powering the module from a –48-V telecom
central office supply, this input is connected to the primary system ground.
–VI: The negative input supply for the module, and the 0 VDC reference for the Remote On/Off input. When
powering the module from a +48-V supply, this input is connected to the 48-V return.
Remote On/Off: This input controls the On/Off status of the output voltage. It is either driven low (–VI potential),
or left open-circuit. For units identified with the NEN option, applying a logic low to this pin will enable the output.
And for units identified with the PEN option, the output will be disabled.
VO Adjust: Allows the output voltage to be trimmed by up or down between +10% and –20% of its nominal
value. The adjustment method uses a single external resistor. Connecting the resistor between VO Adjust and
–VO adjusts the output voltage lower, and placing it between VO Adjust and +VO adjusts the output higher. The
calculations for the resistance value follows industry standard formulas. For further information consult the
application note on output voltage adustment.
+VO: The positive power output with respect to –VO, which is DC isolated from the input supply pins. If a negative
output voltage is desired, +VO should be connected to the secondary circuit common and the output taken from
–VO.
–VO: The negative power output with respect to +VO, which is DC isolated from the input supply pins. This output
is normally connected to the secondary circuit common when a positive output voltage is desired.
Sense(+): Provides the converter with an output sense capability to regulate the set-point voltage directly at the
load. When used with Sense(-), the regulation circuitry will compensate for voltage drop between the converter
and the load. The pin may be left open circuit, but connecting it to +VO improves load regulation.
Sense(–): Provides the converter with an output sense capability when used in conjunction with Sense(+) input.
For optimum output voltage accuracy this pin should always be connected to –VO.
