Output Voltage Programming Information
Pin Descriptions
+Vin:
The positive input for the module with respect to
–V
in
. When powering the module from a –48V telecom
central office supply, this input is connected to the primary
system ground.
–Vin:
The negative input supply for the module, and the
0VDC reference for the Remote On/Off input. When
powering the module from a +48V supply, this input is
connected to the 48V(Return).
Remote On/Off:
A positive logic input that is referenced to
–V
in
. Pulling this input down to –V
in
potential disables
the module’s output. If this input is left open-circuit, the
module will produce an output whenever a valid input
source is applied.
VID0
–
VID4:
Selects the set-point output voltage of the
converter according to the applicable program code.
VID0 – VID4 must either be connected to (–)Remote
Sense or left open circuit.
Note: For the PT4402 & PT4403,
VID 4 is internally disabled and may be left open circuit.
+Vo:
The positive power output with respect to -V
o
, which
is DC isolated from the input supply pins. If a negative
output voltage is desired, +V
o
should be connected to the
secondary circuit common and the output taken from –V
o
.
–
Vo:
The negative power output with respect to +V
o
,
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.
+Remote Sense:
Provides the converter with remote sense
capability to regulate the set-point voltage directly at the
load. When used with –Remote 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 +V
o
will improve load regulation.
–
Remote Sense:
This is the logic ‘0’ reference for the
inputs VID0 – VID4, and provides the converter with
remote sense capability when used in conjunction with
+Remote Sense. For optimum output voltage accuracy
this pin should always be connected to –V
o
.
