REDUNDANT AUXILIARY POWER SUPPLY FOR AUTOMATIC BYPASS
The TRIPOWER X31 HE is equipped with a redundant auxiliary power supply that enables the UPS to run on an automatic bypass
even when a failure occurs in the main auxiliary power supply. If a fault occurs in the UPS shutting off the main auxiliary power
supply, the load is powered by the automatic bypass. The multiprocessor board and the control panel are not powered so the
LEDs and the display are off.
PROGRAMMABLE AUXILIARY SOCKET (POWER SHARE)
The TRIPOWER X31 HE has an output socket that enables the load applied to it to be disconnected automatically under certain
operating conditions. The events that determine the automatic disconnection of the Power share socket may be selected using
the configuration software UPSTools (see the Configuration software and UPS Configuration paragraphs).
For example, the socket can be disconnected after a given time of battery operation, or when the battery low prealarm threshold
is reached or an overload occurs.
Safety notes: when the UPS is switched on, if the output switch (SWOUT) is opened, the Power share socket will
remain connected to the mains.
If the manual bypass switch (SWMB) is inserted, the output switch (SWOUT) is opened and when the UPS is
shutdown, the socket will be disconnected.
POWER WALK-IN
The TRIPOWER X31 HE has a Power Walk-in mode which can be enabled and configured using the software UPS Tools. When
the mode is enabled and mains power is restored after a period of battery operation, the TRIPOWER X31 HE starts to draw
progressively from it so as not to stress (due to the peak) any generating set installed upstream. The transient time may be set
from 1 to 30 seconds. The default value is 10 seconds. During the transient, the necessary power is drawn in part from the
batteries and in part from the mains, maintaining sinusoidal absorption. The battery charger is turned on again once the transient
has passed.
REDUCING THE LOAD (TO 200V AND 208V)
If the output voltage is set to 200V and 208V (see “Configuring the TRIPOWER X31 HE” paragraph), the maximum power output
of the UPS is reduced with respect to its rated value, as shown in the graph below:
