General Characteristics
UPStealth® Inverter/Controller is an Intelligent Two-Stage BBS. Stage one continuously monitors the power line and decides if
the power available to the tra
ffi
c cabinet is adequate for safe operation of the tra
ffi
c cabinet. If utility power is within the user
de
fi
ned parameter range, it is routed through a transient suppression and
fi
lter module to clean up the incoming power. When
utility power is outside of normal operating parameters, a power failure is detected, and the Inverter/Controller will switch over
to battery backup power. The switch to battery power typically takes about 6 milliseconds (msecs). Switch-over times can be
programmed by the user up to 200 msecs.
Stage two, is the digital sine wave monitoring system. This system models the incoming sine wave in real time and detects sine
wave abnormalities. User-settable thresholds allow the end-user to customize the sensitivity of the UPStealth® to assure
downstream equipment is completely protected from even the smallest power deviation. When the digital sine wave monitoring
system detects an abnormality, the Inverter/Controller switches the intersection to battery backup and the triggering sine wave
is stored in the Event Log, along with a day/date time stamp. The actual waveform of the power line voltage can help in
analyzing power problems that may be causing equipment malfunctions
UPStealth® Inverter/Controller is available in two di
ff
erent physical con
fi
gurations: A NEMA version, and a 170 version. The
“NEMA” Inverter/Controller is made to sit on a shelf or be rack mounted. All of the connectors, keypad and LCD display are on
the front of the unit. The “170” Inverter/Controller is 2U high and is rack mountable. The connectors are on the back panel of the
“170” unit and the LCD display, keypad, and Ethernet interface are on the front.
UPStealth® Inverter/Controller has four plastic circular connectors, where the Battery Panel connector cables attach. This means
four Battery Panels can be directly connected to the Inverter/Controller. If more Battery Panels are needed, an expansion HUB
can be connected to any of the ports on the Inverter/Controller. The HUB will expand the capability of that port to connect to
four Battery Panels. Therefore, if you put a HUB on each Battery Panel Port on the Inverter/Controller, you could have a total of
sixteen (300/500 Watt) Battery Panels connected to one Inverter/Controller.
There are several di
ff
erent types of Battery Panels available. Standard Battery Panels include the 300 and 500 Watt
UPStealth® Living-Hinge Batteries for installation between the rack and the cabinet wall of a 170 style tra
ffi
c cabinet. UPStealth®
Living-Hinge is available in a 300 Watt and 500 Watt Battery Panels which
fi
t in 170/2070 33X series tra
ffi
c control cabinets. A
UPStealth® 500 Watt NEMA Battery Panel is also available which can be shelf mounted or rack (19”) mounted.
