In the event of mains problems (e.g. power outages), power is supplied to the
load segment without an interruption from the inverter, which now uses the
battery. Since no switching is required, the load segment experiences no power
supply interruption at all.
The automatic bypass provides increased power supply security for single
installations in particular by switching the public network, e.g. in the event of
an inverter malfunction, through to the load segment directly and without
interruption. In other words, the automatic bypass provides the load segment
with an additional passive redundancy.
An integrated, manual bypass unit for maintenance and / or servicing provides an
uninterrupted supply of power to the consumers. The connection unit is designed
so that it can be separated from the UPS circuitry with minimal effort and can thus
remain in the rack. Through this simplified line-side activation, servicing of the unit
is possible at all times.
In order to ensure maximum security to the supply of the connected loads,
the equipment was also prepared for parallel operation: a second UPS system
provides maximum availability when used as an active redundancy. If, however,
the demand for power is in the foreground, then the second UPS can be used
for performance enhancing parallel operation.
The graphical LCD display used provides for versatile use and easy operation.
Convenient features such as switchable outputs, a freely programmable,
potential-free change-over contact, as well as an emergency power-off contact,
round out the standard interface selection (USB, RS232 and communication slot).
