Multi-SWITCH improves electrical supply continuity. The principle of
operation guarantees a higher reliability level than that achieved using a
single UPS (on-line with automatic bypass) or several UPS in parallel.
PRINCIPLE OF OPERATION
The Multi-SWITCH provides electrical distribution and remote
management for up to eight network users, powered from two direct
mains supplies or UPS or a combination of both.
The Multi-SWITCH can connect each user (up to eight, each with a
maximum power demand not greater than 4A), to either of the two
power sources (A and B). Load demand is shown on the LCD. See
“principle of operation” diagram.
PROTECTION AGAINST POWER SUPPLY FAILURES
If one of the two power source fails or falls outside specification, Multi-
SWITCH will transfer the connected loads to the second power source
(switching is instantaneous even if the two sources are in phase).
PROTECTION AGAINST LOAD FAULTS
If a fault occurs with one of the loads (for example due to a short-
circuit or overload), Multi-SWITCH will disconnect the load to prevent
disruption to the others. Multi-SWITCH protects sensitive installations
from both power and hardware faults.
CHARACTERISTICS
• Full protection against mains failures and load faults
• flexible power sources: Multi-SWITCH can be powered from 2
different sources (2 mains supplies, 2 UPS or a combination of both.
Note than the UPS can be of a different size)
• designed for installation in a 19” rack-mount cabinet
• LCD to provide measurements/alarms/states information
• remote monitoring serial interface
• no signal connection is required between Multi-SWITCH and the
power sources or supplied hardware
• configuration software provided as standard
• slot-in SNMP network adapter card.
