Automatic Transfer Switch
HIGHLIGHTS
- Redundant power supply
- Load protection
- Versatile to use
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 from one source to the other is performed according to the ITIC (CBEMA) times chart and so it does not impact the operation of the connected equipment. 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 PowerShield 3 software, Web interface, SNMP, or SSH which makes the Riello UPS Multi Switch an ideal device for the IT manager who needs flexibility and protection for their IT equipment. Multi Switch 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 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. Depending on the ITIC curve, typical power supplies will operate 20 ms after AC voltage drops to zero. The IEEE 1100-1999 standard also references the ITIC curve. The SSI (Server System Infrastructure) standard recommends a hold-up time for power supplies to be a minimum of 21 ms for a voltage range of 100-240 V. 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 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 components.
FEATURES
- Full protection for loads against mains and load failures;
- Redundant power supply;
- Flexible: Multi Switch can be powered with 2 different power supplies (including 2 UPS of different sizes/types);
- 19” cabinet installation;
- LCD Display panel;
- Compatible with PowerNetGuard supervision software;
- No signal connection between the Multi Switch and the power sources or loads is necessary;
- Slot for communications boards: the optional network card allows for remote in network connectivity and management through HTTP, SNMP and SSH protocol.
