Protection against possible operator error:
The ELI is designed with
breaker on/off sensors and power supply sensors. These sensors prevent
potential operational mistakes from interfering with the start –up operation
causing possible damage.
k.
Wide input range:
The components are overrated by design to handle high
input voltages and currents without harm to the system, ensuring that Tycor
UPS ELI’s remain one of the most reliable ELI Systems available in
today’s market.
l.
Harsh environment:
Each component of the ELI is chosen with the highest
degree of safety margins allowing for wider environmental parameters and
specifications related to temperature, humidity, altitude, surge or noise.
m.
Intelligent charger:
The ELI will automatically recharge (boost charge) the
batteries when the battery voltage level decreases to approximately 2V/Cell
or to a user specified level. To prevent the over-charging of the battery, the
boost charge will stop when batteries achieve a 90% charged level or the
ambient temperature reaches 35
o
C (95
o
F) at which point the float charging
begins.
n.
Intelligent battery test:
The batteries are tested after every boost charge
whether the charge has been initiated by a battery discharge state (2V/Cell)
or by the regular battery test performed by the ELI (monthly test). When an
abnormal condition (low charge rating, or bad battery) is found the user will
be informed immediately through alarms on the ELI system.
o.
Charging rate:
The charging rate is selectable (L/M/H) according to Ah
ratings of the batteries. The charger is designed to charge the larger battery
banks without adding an additional charger (up to 8hr. back-up).
p.
MTBF of cooling fans:
Long cycling fans will operate at variable speeds
necessary which is dependent on the ambient temperature of the ELI system
increasing the life expectancy of the fan motors.
q.
Redundant power supply:
Redundant power supplies have been installed
to allow for worry free operation of the system.
r.
Intelligent interface:
One remote control panel (or one PC) can monitor and
control up to ninety-nine ELI’s. The communication allows for N+1
redundancy, whereby if one system encounters an emergency or fault
condition, it will warn the user immediately and the load is automatically
transferred to the other ELI systems. The ELI status, data or commands are
transmitted to external modules through four RS-485 ports.
s.
Data log capability:
All abnormal conditions will be stored within the ELI
control interface board for further reference by the user. Each abnormal
condition is time and date stamped (real-time clock) as the event occurs. This
history is stored and cannot be removed even if or when the ELI is turned off
for servicing.
