Source supplying the bypass line. The equipment can be transferred to the
bypass line if an overload occurs on the UPS output, for maintenance or in
the event of a malfunction.
Operating mode used to convert the AC-power frequency between the UPS input
and output (50Hz -> 60Hz or 60Hz -> 50Hz).
This is a battery-voltage level indicating that battery power is low and that
the user must take action to prevent the imminent break in the supply of power
to the load.
Time during which the load can be supplied by the UPS operating on battery
power.
Devices or equipment connected to the UPS output.
Operating mode by which the load is supplied directly by the AC source if it is
within the tolerances defined by the user. T his mode reduces the consumption
of electrical power
Rotary switch controlled by the user, used to connect the loads directly to the
AC source. Transfer of the load to the manual bypass enables UPS maintenance
without interrupting the supply of power to the connected loads.
The normal UPS operating mode in which the AC source supplies the UPS which
in turn supplies the connected loads (after electronic double conversion).
Input source of power for the UPS.
Contacts supplying information to the user in the form of signals.
Uninterruptible Power Supply.
