inverter during the normal operating mode. Therefore, Inverter static switches are active if
there are no problems with the system.
System provides the loads to be fed smooth and seamless by mains or inverter. In order to
manage this process at minimum risk, UPS synchronizes the inverter output and static (mains)
bypass as phase and frequency. Therefore, Inverter frequency can be considered same with
mains as long as it is within frequency limit.
User can switch between mains and inverter by using front panel. When the inverter is ready,
while the loads are fed through the bypass line, in case of either power failure or if mains values
are out of tolerances, the loads automatically will be fed through the inverter.
2.1.2 Battery Temperature Regulation
In the external battery cabinets the battery temperature is measured and detected by
"temperature sensor”. UPS adjusts battery charge parameters according to
the detected
temperature.
2.2 UPS’s Operation Modes
LEVELUPS series is on-line double conversion device. Our products operate in the following
modes:
➢
Online Mode
➢
Battery Mode
➢
Bypass Mode
➢
Auto Restart
➢
Maintenance Mode
2.2.1 Normal (Online) mode
In this mode, UPS feeds the load through the inverters. Rectifier unit is fed by the AC mains
power. Inverter and battery charge units are fed by DC supply generated by rectifier unit.
2.2.2 Battery (Stored) Mode
When the mains voltage is bad the UPS runs on battery mode. UPS feeds the critical load through
the inverter; the energy is obtained from batteries.
2.2.3 Bypass Mode
In case when UPS is overloaded or if inverter cannot generate a quality AC output due to any
problem and if bypass voltage and frequency values are within the limits, the loads will be fed
from the static bypass source (mains). UPS without interruption switches from inverter to AC
source (mains) via static transfer switches. The inverter source and mains must be synchronized
in order to manage smooth switching. If inverter output and mains are not synchronized,
switching may take up to 15 msec, varying according to load type.
