Xgen FLEXIBILITY and SIGNALS
Voltage Adjustment - Local
The multi-turn potentiometer that adjusts each output within the speci-
fied range may be accessed via the output panel of the power supply.
Clockwise rotation increases output voltage. Resolution is approximate-
ly 5% of nominal voltage (Vnom) per turn.
Voltage Adjustment - Remote (resistive / electronic)
The output voltage may be adjusted or trimmed by means of an exter-
nal resistor or potentiometer network connected to the Vtrim pin. Linear
Electronic programming is also possible and may be implemented
according to the formula Vout = K Vcontrol. See Xgen series
Designers’ Manual for full details.
Paralleling
To achieve increased current capacity, simply parallel outputs using the
standard parallel links. Excelsys ‘wireless’ sharing ensures that current
hogging is not possible. To parallel connect outputs:
1. Switch on IShare switch to ON on powerMods.
2. Connect Negative parallel link.
3. Adjust output voltages of powerMods to within 5mV of eachother.
4. Connect Positive Parallel Link.
Seriesing
To achieve increased output voltages, simply series outputs using stan-
dard series links, paying attention to the requirements to maintain
SELV levels if required in your system.
Remote Sensing
When the load is remote from the power supply, the remote sense
pins may be used to compensate for drops in the power leads.
Where the power cabling contributes significant dynamic impedance,
see Xgen series Designers’ Manual.
Bias Voltage
A SELV isolated 5V (always on) bias voltage rated at 250mA is pro-
vided on J2 to facilitate miscellaneous control functions.
Current Limit Adjustment
The output current limit setting may be adjusted (downwards only)
by means of an external resistor connection to the I trim pin.
Inhibit/Enable
Inhibiting may be implemented either globally or on a per module
basis (powerPac or powerMod inhibiting). Reverse logic (Enabling)
may also be implemented, see Xgen series Designers’ Manual.
AC Fail
Open collector signal indicating that the input voltage has failed or is
less than 80Vac. This signal changes state giving 5mS of warning
before loss of output regulation. See Xgen series Designers’ Manual
for full specifications.
Parallel Links available to

Series Links available. Part
Number XS1
Temperature Alarm (Option 01)
Open collector signal indicating excessive powerPac temperatures due
to fan failure or operation beyond ratings. This signal is activated at
least 10ms prior to system shutdown.
Fan Fail (Option 01)
Open collector signal indicating that at least one of the system fans
have failed. This does not cause system shutdown.
Power Good
Opto-isolated output signal indicates that the powerMod is operating
correctly and output voltage is within normal band.
Opto transistor ON = Good.
Indication LEDs
Each powerMod has a visual indicator to identify that it is operating
within normal ratings. Very useful for system diagnosis.
