The Riello UPS Multi Switch ATS is a high
availability intelligent switch that provides
redundant power to connected equipment
with two AC input sources. The Riello UPS
Multi Switch ATS 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 ATS 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 ATS has
8 IEC 10 A and 1 IEC 16 A outlets allowing
several devices to be plugged directly into
the ATS without the need for an additional
PDU. The units have a connectivity slot
which allows for LAN connection and
remote management through PowerShield3
software, Web interface, SNMP, or SSH
which makes the Riello UPS Multi Switch

ATS an ideal device for the IT manager who
needs flexibility and protection or their
IT equipment. Multi Switch ATS provides
installations with power supply continuity.
Its operating principle ensures higher
reliability than a single UPS, (with or without
its own internal bypass).

Operating principle
Multi Switch ATS provides direct distribution
of eight 10 A IEC outlets or one 16 A IEC outlet
in a system with two input power lines (two
mains inputs, or two UPS). Multi Switch ATS
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),
the Multi Switch ATS 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).

recommends a hold-up time for power
supplies to be a minimum of 21ms for a
voltage range of 100-240V. Multi Switch
ATS 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
frequency are in range. Any point of failure
in the electronics does not cause a drop
out of the output voltage because the unit
incorporates redundancy of its electronic
circuitry to avoid fault tolerance.

Features
•t t Full protection for loads against mains and
load failures

•t t Redundant power supply
•t t Versatile to use: Multi Switch ATS can
be powered with 2 different power
supplies (including 2 UPS of different
sizes/types)

Protection against power
supply faults
If one of the two power sources falls
outside tolerance levels, Multi Switch
ATS will transfer the load to the second
power source (switching is instantaneous if
the two sources are in phase). Multi Switch
ATS 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 curve. The
