T3R SERIES (rackmount)
With ever greater demands being made on
valuable floor space, many IT managers are moving towards
computer rack solutions rather than conventional floor
standing options offered in the past. The same philosophy
has affected the UPS industry with many UPS now being
located with the computer inside the rack cabinet.
On-Line UPS have historically been handicapped
in this particular market sector, essentially for two
reasons, size and price. Most IT managers have dealt
with this problem by moving to Line-Interactive or Off-Line
topologies. As these technologies have fewer fail safe
features and for the most part work only when a problem
occurs. With the introduction of the T3R series these
past limitations are no longer valid.
The T3R is a physically small On-Line
double conversion UPS but retains all the features normally
associated with On-line technology, but what is On-Line
double conversion technology and why does it matter?
Simply put, “double-conversion” is where
the mains supply is rectified to a clean DC voltage
and rebuilt into a very clean and regulated AC voltage
at all times your critical load runs from this clean
no break supply.
Line-Interactive and Off-Line UPS are
single conversion, put in its crudest form, your computer
runs on semi regulated mains and will always suffer
a small break in supply whist the UPS moves from mains
mode to battery mode in a mains fail situation. The
T3R offers a competitive price, even against the more
basic technologies, but unlike these technologies you
will get as standard an LCD screen, RS232, USB port,
battery extension options, battery monitoring, no-break
supply, static switch, wide voltage input without using
batteries, optional software, comms slot for SNMP, Relays
or Optocoupler. |

AVR Automatic Voltage Regulation:
Not all off-line or line-Interactive
UPS have an AVR. The benefit of an AVR, which is
essentially a switching transformer, is that the
voltage can be regulated without having to engage
the batteries; this feature dramatically extends
battery life. AVR’s are not normally required with
On-Line UPS.
Long Back Up Times:
Typically UPS have a standard run
time of between five to ten minutes, but the demand
for longer autonomies is growing, especially in
the area of telecoms. For UPS to be able to offer
longer run times the system has to be able to offer
additional battery charging and a continuously rated
power output stage, when you see this logo against
a product you can rest assured that a reliable battery
recharge and extension run time can be provided.
Surge Protection:
Surge protection is vital for today’s
modern commutations equipment; surges can take two
forms, (1) high speed (transient spike) (2) slow
voltage increase, typical in factories or end of
grid situations. Surges are not just an increase
in voltage but also in energy, it is the power stored
in the surge that can cause the most damage, when
you see this logo relax, surge protection is on
hand.
Software:
When you see this Icon you have available
to you a wide variety of power management and shutdown
options.
Digitech:
Yes, you have guessed it, when you
see this icon you have the comfort that your AEC
machine is using digital control, this offers incredible
reaction time to anomalies that the mains may try
and throw at your network

INTERNAL SNMP SUB-AGENT FOR INTEGRATION INTO EXISTING
NMS (e.g HP OPENVIEW, CA UNICENTER) |
SIMPLE NETWORK MANAGEMENT PROTOCOL
(SNMP)
The T3R SNMP external agent can be located
up to 5 metres away from the UPS. Initial configuration
is carried out by serial comms using any suitable terminal
application (e.g. Hyperterminal for Windows).
The embedded HTTP server presents an HTML
interface to the network, which can be accessed from
any web browser.s All system parameters can be configured
from here, including scheduled shutdown. A sophisticated
Java applet provides full monitoring in real time, along
with comprehensive event and history logs.
UPS MANAGEMENT SOFTWARE
The UPS management software is installed
on a server or workstation connected to each UPS via
the serial port. Power failure, power restored, battery
failure or eight events will be detected and the user
informed. A shutdown will be initiated when the batteries
are exhausted or a technical problem occurs with the
UPS. The UPS management software disconnects network
connections, logs out users and closes open applications
(subject to app/os support) before shutting down the
operating system itself.
