Output voltage can be adjusted in a number of ways:
1. On board multi turn potentiometer
2. Remote resistive programming (via Vtrim pin)
3. Remote voltage programming (via Vtrim pin)

Output current limit can be Straight line or Foldback and can be
adjusted via Itrim pin.

To achieve increased current
capacity, simply parallel outputs
using the standard parallel links.

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.

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.

A SELV isolated bias (always on) voltage of 5V @ 250mA
(30mA on XCE and XVE models) is provided on J2 pin 2 relative
to J2 pin 1 (common) and may be used for miscellaneous
control functions. 5V @ 500mA available on request.

Inhibiting may be implemented either globally or on a per
module basis (powerPac or powerMod inhibiting). Reverse logic
(enabling) may also be implemented.

Open collector signal indicating that the input voltage has failed
or is less thant 80Vac. This signal changes state giving 5ms of
warning beore loss of output regulation.

Opto-isolated output signal indicates that the powerMod is
operating correctly and output voltage is within normal band.

'19<1=-?@=18-=9"<?5;:
Open collector signal indicating that excessive temperature has
been reached due to fan failure or operation beyond ratings. This
signal is activated at least 10ms prior to system shutdown.
-:-58"<?5;:)
Open collector signal indicating that at least one of the
powerPac fans has failed. This does not cause power supply
shutdown. The power supply will continue to operate until 10ms
after the temperature alarm signal is generated.
