KEOR T 120 kVA
Legrand UPS model Keor-T 120 is an uninterruptible power source
with 3-Level IGBT switching technology, high frequency PWM
technology, Double Conversion On-line, solid neutral, with the
possibility to have on site modular redundancy up to total 8 units, Rated
Power 120 kVA – 108 kW.
Batteries are lead acid, sealed, free maintenance, valve regulated, and
arranged in external battery cabinet.
1.1 Architecture
Legrand UPS model KEOR T 120 has stand-alone architecture.
UPS is composed by following parts;
- IGBT Rectifier/PFC
- 3-Level IGBT Switching Technology
- Digital Signal Processor (DSP)
- 3.5” TFT Touch Panel
- Automatic Bypass
- Dual Input Bypass
- Internal Manual Bypass
- Standard Internal Backfeed Protection
- Internal Battery Drawer Shelves
The UPS can be easily configured on site, by the authorized personnel,
to operate in parallel. Also it is possible to arrange the dual bypass by
removing bridge connection on each input phase.
Legrand Keor-T 120 has 3-Level IGBT switching technology and there
is no transformer in the unit. These provide high efficiency for the unit.
Backfeed protection provides additional protection at the input in the
event of bypass thyristors are short circuited.
By using internal backfeed contactor in bypass line provides safety
when fault situation occurs in static bypass line and prevents upstream
energy to the input.
The internal backfeed protection provides an easy on site installation
without any additive cabling or special MCCB type in the upstream
distribution panel
1.2 Redundancy:
The Redundancy of the UPS allows N+X redundant and power
upgrade configurations. Parallel feature is standard at Keor-T 120.
Up to 8 units of same size UPS can be connected in parallel.
1.3 By-pass
Keor T has internal both static bypass and mechanical (maintenance)
bypass as standard. Addition to this input and bypass inputs can
easily be separated to obtain dual input by removing the bridge on the
connector.
1. GENERAL SPECIFICATIONS
1.4 Control and Monitoring:
Keor T is equipped with a touch screen graphic TFT display that
provides information, measurements, statuses and alarms of the UPS
in different languages. Below this display, there is a multicolour LED
bar showing status of UPS.
- GREEN: Normal or ECO Mode Operation
- ORANGE: Bypass or Battery Operation
- RED: Load not Supplied
A dedicated software of remote monitoring and management, installed
on a PC connected to the UPS, allows to check and set all working
parameters of Keor T (the same functions available on the UPS control
panel) and, furthermore, to schedule and program computer remote
shutdown. Optional software (UPSMAN) or Net Interface card (CS121
SK) allow the multi server shutdown and UPS remote control on the
LAN. Also, standard interface board comes with;
- RS232 Serial Communication Port
- Emergency Power Off (UPS OFF)
- Generator Contact (GEN ON)
- 4pcs programmable Dry Contact Information
- 2 contactor relays for Bypass and Battery
- ModBus (over RS485, with 2400 Baud Rate)
Standard Dry Contact Alarms are General Alarm, Bypass Active, Input
Failure and Synchronization OK. Addition to these; High Temperature,
Battery Test Failure, Output Failure alarms can be assigned to the
contacts. Each alarm can be assigned to separate contacts but also
one alarm may be assigned to all contacts.
Keor T front panel is controlled by DSP microprocessor which works
together with DSP microprocessors in rectifier and inverter; by display
is possible to check all measurements, working parameters and status
of the system.

the display:
