I. GENERAL DESCRIPTION
1.1 Introduction
T-300P Uninterruptible Power Supplies, are On-Line UPS’s, being manufactured with the state-of-the art PWM
and IGBT technology, produce microprocessor controlled pure sine wave output to critical loads. T-300P series
UPS’s install between the critical load and the mains.
The advantages of using UPS:
•
Power blackout protection:
If the mains power fails, the UPS continues to power the critical load from its battery source, leaving the load
immune from power disturbances.
•
Increased power quality:
The UPS has its own internal voltage and frequency regulator circuits, which ensure that its output is
maintained within close tolerances independent of voltage and frequency variations on the mains power lines.
•
Increased noise rejection:
By rectifying the input AC power to DC power, and then converting it back to AC, any electrical noise present
on the input mains supply line is effectively isolated from the UPS output, therefore the critical load sees only
clean power.
Features:
•
Parallel mode operation (optional) up to 2 UPS. (1 redundant)
•
On-line technology with pure sine wave output.
•
PWM and IGBT technology.
•
3 Microprocessors at each UPS
•
Microprocessor controlled main controller board.
•
Microprocessor controlled rectifier board.
•
Microprocessor controlled parallel control board.
•
Static (STS) and maintenance by-pass.
•
LCD (Liquid Crystal Display) display.
•
Alarm history (Memory for max. 64 alarms.)
•
High quality maintenance-free lead-acid type batteries.
•
High nonlinear load capacity, special for computers.
•
Automatic and Manual Battery Test System:
After all the pre conditions ensured, the battery test is made periodically by itself.
•
Interactive battery management system (optional)
•
Nonlinear loads driving capability.
•
Facility of connection with the PC:
In case of failure, alarms of the UPS (Battery low, mains control or general) are shown by the dry relay
contacts and RS232, to the user. The relay interfaces are specially produced for the server systems
(IBM AS400 and Microsoft Windows NT).
•
Accessories:
o
Optional UPS monitoring software ( RUPS

, RUPSII

, UPSILON

) SNMP devices, compatible to
any operating system.
o
Remote Monitoring Panel (RMP) available: You can observe the UPS status and parameters without
using a computer at a remote location up to 200 meters away (via RS485 interface). Up to 5 remote
monitoring panel connection is possible.
o
UPS Port Sharer up to 24 server is available
