-Liebert GXT MT+ is able to deliver 11% more active power than conventional
10 - 20 kVA UPS which have a PF of 0.8.
- As a result Liebert GXT MT+ avoids the need for system over sizing while
delivering the same level of power to the load.
Full compatibility with all type of load
 Full compatibility with all types of loads
with PF up to 0.9 without de-rating
 Fully compliant with leading power factor
loads
 UPS do not require de-rating for leading
power factors and can be connected to
any load within the nominal kVA and kW
rating of the UPS regardless of power
factor.
Optimum TCO : Excellent OPEX
Double Conversion Mode
maximizes performances with any kind of
load and with any condition of the electrical
environmental Under normal conditions,
Efficiency up to 92.5%
Line Interactive Mode (ECO mode)
maximizes energy savings.
Liebert GXT MT+ operates under line
Interactive Mode as energy saving operation,
Efficiency > 97%
Charging Capacity
“Liebert GXT MT+ has 5.0 kW
of charging capacity “
This means…. it will recharge the same battery approx…
• 1.4 times faster than a UPS with 3 kW of charging power
• 2 times faster than an UPS with 2 kW of charging power
...alternatively…. it will charge a battery 1.4 to 2 times larger
(Ah) in the same amount of time.

Liebert GXT MT+ Features and benefits
Feature
Benefit
Three level inverter/rectifier
The voltage stress of the UPS semiconductors is reduced by half, thus
ensuring prolonged life of the critical components.
Replaceable power subassemblies
Easy replacement in the event of failure significantly reduces the mean time to
repair (MTTR).
High Efficiency
Greatly reduces OPEX and return on investment.
Unprecedented integrated
autonomy
Virtually eliminates the need for an external battery cabinet and the costs
associated with its installation.
Output PF=0.9
11% more active power compared to a 0.8 PF UPS eliminates the need for
overseeing the system and delivers increased savings.
Input PF=0.99
Minimizes installation costs by enabling the use of smaller generators, cabling
and circuit breakers.
Integrated circuit breakers
Simplifies installation and reduces the need for external devices
Integrated Inbuilt Paralleling
Allows the deployment of the N+X redundancy and integrated parallel control in
each module ensuring total redundancy
Integrated External transformer
option
Makes Liebert GXT MT+ compatible with:
• Medical and other critical applications
• Installation with two independent input sources
• Installation in distribution without neutral.
External battery flexibility
Allows a wider choice of battery and possible re-use of existing battery banks
High kW battery charger power
Allows for effective reduction of the battery re-charging time and increases its
ability to manage long run times.
Customer Problems/Challenges
Space constrained, server rooms and network closets.
Expensive service costs for installation and maintenance
of IT devices/equipment.
Too many assets to manage and stock.
Generator outputs frequency variations onto the load.
Lack of ability to remotely
manage multiple locations.
Human error.
Availability of critical applications
during power disturbances
Not enough Runtime
Configuring Correct Solutions for
Customers
Important things to ask
 What is your expected load today? In the future?
 How much runtime do you need from the UPS today? In the future?
 Rack or tower form factor? If rack, how many racks will you be powering? Will each
rack require one or two rack power distribution units? Who is your current rack
vendor and are you happy with them?
 What input power (voltage and breaker size) is available?
 What Output voltage is required?
 What kind of output receptacles will you need? (How many power supplies or power
cords does your equipment have?)
 How much floor space is available?
 Are you going to power loads that are in different rooms?
 How will you be managing this UPS? Is remote management valuable?
 What kind of service do you expect from Emerson?
 Do you want redundancy and/or run time scalability to increase availability?
 Do you require an external maintenance bypass?
 Do you have other Emerson UPS? If so, would you be interested in inventory
management for all of them?
Handling Objections from customers
Q: I’m concerned with buying such a new product
R: The GXT Family was launched May 2003 as the GXT MT in Europe and Asia. It was renamed in
early 2005 to GXT MT+. The inverter design is actually based on a Third level inverter design that
started shipping in 1997. These designs are among the most robust available.
Q: I already buy Brand “L”. Emerson on-line UPS are not as good as Brand “L” since Brand
“L” specialize in online and are on the 4th generation
R: Liebert GXT MT+ will match spec with any competitor. GXT MT+ has won many awards world wide,
beating out the legacy competitors. Many of the design engineers on the GXT MT+ design team
came from legacy online UPS companies. Additionally Emerson designs and manufacturers the
online UPS; many legacy competitors DO NOT design or build their single phase UPS‟s anymore.
Q: The Run Time is not long enough for my application.
R: Run time is based on Watts and Battery capacity. The 10 kVA provides more than 2 hours Back up
at “full load” of 9 kW and 20 kVA provides approximately 1 hour Back at „‟ full load of 18 kW.
Traditional legacy UPS supply only 8000 watts.
Q: Brand X has dual input feeds. I think I want this.
R: This feature is of significant value if the end user has separate utility power feeds from different
power generators which is very rare. Nuisance tripping of input breaker and user error on the
input side of the UPS can usually be correct in the time the UPS is on battery. Most customers
with this feature in this UPS space will end up tying the feeds together into a single feed like the
GXT MT+ has rather than expending the time of wiring separate feeds on the same circuit.
