KEOR T 20 kVA
Legrand UPS model KEOR T 20 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 N+X on site modular redundancy up to total 8
units, Rated Power 20 kVA–18 kW.
Batteries are lead acid, sealed, free maintenance, valve regulated,
and arranged, inside the UPS in dedicated Drawers or external
battery cabinet.
The architecture of this UPS is a Tower type. Two different cabinet
sizes are available for internal battery configuration. 1345h cabinet
is sized to guarantee a minimum uptime of 8 minutes and 1650h
cabinet is sized to guarantee a minimum uptime of 24 minutes at
70% of 0,9PF load.
It is possible to install 60pcs battery (7Ah or 9Ah) to 1345h cabinet
and 120pcs battery (7Ah or 9Ah) to 1650h cabinet.
1.1 Architecture
Legrand UPS model KEOR T 20 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 20 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 configurations.
Up to 8 units of same size UPS can be connected in parallel.
1. GENERAL SPECIFICATIONS
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.
1.4 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.
Here follow the measurements and working parameters available on
the display:
