curve. The SSI (Server System Infrastructure)
standard recommends a hold-up time for
power supplies to be a minimum of 21ms for
a voltage range of 100-240V.
Multi Switch units switch sources under these
industry standard times. The switching time
includes the time for the built-in intelligence
to determine whether the voltage and
Operating principle
The Riello UPS Multi Switch is a high
availability and versatile intelligent switch
that provides redundant power to connected
equipment with two AC input sources. The
Riello UPS Multi Switch supplies power to
the connected loads from a primary mains
source. If that primary source becomes
unavailable, the Riello UPS Multi Switch
automatically transfers loads to the secondary
source. The transfer time from one source
according the ITI (CBEMA) chart does not
impact the operation of the connected
equipment as the switching occurs safely
between the two input sources regardless of
any phase differences. The Riello UPS Multi
Switch monitors the current and provides
warnings when power consumption draws
near the maximum rating which helps prevent
downtime to the equipment.
Riello UPS Multi Switch has 8 independent
IEC 10 A outlets allowing several devices can
be plugged directly into the Rack without the
need for an additional Rack PDU. The units
have a connectivity slot which allows for LAN
connection and remote management through
PowerShield3 software, Web interface, SNMP,
Multi Switch provides direct distribution
of eight 10 A IEC outlets in a system with
two input power lines (two mains inputs, or
two UPS). Multi Switch is able to connect to
either of the two input power lines, whilst
simultaneously monitoring the power uptake.

Protection against load faults
If one of the loads fails (e.g. short circuit), Multi
Switch disconnects the group of sockets
where the load is connected, thus preventing
other loads from being switched off (i.e. in the
event of poor discrimination of the protection
devices).

Protection against power supply
faults
If one of the two power sources falls outside
tolerance levels, Multi Switch will transfer the
load to the second power source (switching
is instantaneous if the two sources are in
phase). Multi Switch units switch power
with no impact to IT equipment. Per the ITI
Curve, typical power supplies will operate
20ms after AC voltage drops to zero. The IEEE
1100-1999 standard also references the ITI
