01 Output
 Efficiency at Full Load: 99 %
 Output Voltages: 400 V
 Overload Protection shall be available
 Rated Current Draw: 110A
 Overload Capacity: 1.05 continuous
1.10 for 15 minutes
1.2 for 10 minutes
1.50 for 2 minutes
6 for 20 seconds
20 for 20 milliseconds
 Transfer time: ≤5 ms typical
 Unbalanced load conditions: up to 100% continuous current
unbalance
 Manual Bypass
02 Input
 Input frequency: 45 - 65 Hz
 Input Power: 60kW
 Load Power Factor Range: 0.5 Leading and lagging
 Load Capacity: 60kVA
 Maximum Crest Factor: 3.5
 Maximum Input Current: 110A
 Maximum Line Current: 600A
 Maximum permissible THDU for maximum upstream voltage:
15% continuous (without tripping of the protection devices)
 Maximum upstream short-circuit current: 35 kA
03 Environmental
 Operating Temperature: 0 - 40 °C
 Relative Humidity: 20…80 %
 Configurable input contacts for
• Overload reset
• Selection of Source 1 or Source 2 as the preferred source
• Selection of the mode for automatic return transfer

04 Input and Output
Contacts
 Configurable output contacts for
• Load drawing power (presence or absence of power to the
load)
• General alarm (fault on one of the sources or on the device)
• Device alarm (device fault)
• Source 1 "outside tolerances" or "within tolerances"
• Source 2 "outside tolerances" or "within tolerances"
• Source 1 active (SS 1 in ON-state)
• Source 2 active (SS 2 in ON-state)
• Source 1 or 2 selected as the preferred source
• Overload
05 Configuration
Options
 ISX Central, SNMP, and TCP/IP compatible Network
Management Card (NMC)
06 Redundancy &
Reliability
 The STS shall be designed for high reliability and high
availability with an MTBF exceeding 2, 000, 000 hours. To the
fullest extent practical, tri-redundant circuits with voting shall
be used to eliminate single points of failure.
 There shall be two levels of gate drivers on each set of SCRs.
Each level cannot inhibit or out vote the other. Both the
source 1 and source 2 shall have two levels of isolated,
independent gate drivers. One gate driver can be replaced
while under power (“Hot Swap”) without losing any
performance.
 There shall be triple redundant logic power supplies. The
configuration of each DC logic power supply shall be such that
a short circuit on one PCB cannot prevent the other PCBs from
receiving triple redundant power. Each PCB shall receive logic
power via three isolated connectors. The power supplies are
mounted in separate modules so that one-power supply
modules, including the transformers can be replaced while
under power (“Hot Swap”) without any loss of performance.
A. There shall be two levels of operator controls
and status displays:
 Graphical Touch Screen Interface
 Back Up LED Interface
If the normal graphic/touch screen display fails
there is a redundant mimic panel and operator
controls inside the unit. Each operator
control/display PCBs can be replaced while
under power (“Hot Swap”).
