IRMS (Intelligent Redundant Multi-Switch)
Multi-Switch is a rackmount source
transfer switch that can supply up to
eight loads from two AC power sour-
ces. Should one source fails, the other
automatically powers the load. The
sources can be two separate AC sour-
ces including mains power and UPS,
or a combination of the two.
PRINCIPLE OF OPERATION
The IRMS provides electrical distribu-
tion and remote management for up to
eight network users, powered from two
direct mains supplies or UPS or a com-
bination 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 (1 and 2). 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, IRMS will
transfer the connected loads to the
second power source
(switching is instantaneous even if the
two sources are not in phase).
PROTECTION AGAINST LOAD FAULTS
If a fault occurs with one of the loads
(for example due to a shortcircuit
or overload), IRMS will disconnect the
load to prevent disruption to the others.
IRMS protects sensitive installations
from both power and hardware faults.
CHARACTERISTICS
• Full protection against mains failures
and load faults
• Flexible power sources: IRMS 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 infor-
mation
• Management software included
• Remote monitoring serial interface
• No signal connection is required
between Multi-SWITCH and the
power sources or supplied hard-
ware
• Configuration software provided as
standard
• Slot-in SNMP network adapter card
