Details on PWS-RUGGED MINI operation
The unit must be operated with lid open when it is being used as a
charger but can be operated with the lid closed when it is only
supplying output from the on-board batteries.
AC connection is not necessary to have a DC output at 14V and
28V or 48V. The unit needs to be plugged to AC when it is to be
used in charger mode.
If AC is connected, the unit starts to charge any on-board batteries
immediately even if the main power switch is OFF.
If AC is connected but no battery is installed, then no DC output will
be available. At least one battery needs to be present to obtain a
DC output.
If batteries are installed and the device is turned ON, the DC outputs
become available even if AC is not connected. No harm is done to
the unit if loads are being powered by the various outputs while at
the same time, AC is being supplied. The unit will manage the DC
power distribution by itself and can also augment the output power
by up to 60W per battery channel, making use of the additional
power being derived from the mains.
For example:
If a battery (1 station) needs to release 100W in total, 60W will be
provided by AC, whereas the remainder is provided by the battery.
The unit can operate with even just 1 battery on board. It all
depends on the amount of power required by the user. Ideally
however, both batteries should be installed. Each battery is
individually stepped up to 28V-48V, so the total output is the
combination of the outputs of all the batteries installed. It would be
desirable to have the load evenly distributed on the 2 batteries for
these, never to be become overstressed.
Every station is hot swappable and can be monitored from the
display. It is easy to determine how the power is being supplied and
balance the requirement accordingly.
If a battery becomes empty or goes in an overload state, that battery
is excluded from the total output (the user is notified on the display)
We strongly suggest the usage of BLUESHAPE HD and HDplus
batteries because of their high current draw capabilities.
