Xgen FLEXIBILITY
Voltage Adjustment - Local
The multi-turn potentiometer that adjusts each output within the specified
range may be accessed via the output panel of the power supply. Clockwise
rotation increases output voltage. Resolution is approximately 5% of nominal
voltage (Vnom) per turn.
Voltage Adjustment - Remote (resistive / electronic)
The output voltage may be adjusted or trimmed by means of an external
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.
Seriesing
To achieve increased output voltages, simply series outputs using standard
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 provided 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.

Xgen SIGNALS
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.
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.
