SMART-LV SERIES 160 - 200 – 250 KVA PRODUCT DESCRIPTION
2.1 General Information
General operation topology of SMART-LV Series can be recognized as follows:
The UPS is connected to the mains voltage through the CB1 breaker. As DC bus is ramped up, the
rectifier starts to operate. Rectifier converts the AC mains to DC voltage and charges the batteries.
When the mains voltage is not available, the necessary the DC bus voltage is generated with use
of the battery voltage. DC DC bus voltage is then converted to mains synchronized AC voltage by
the inverter. This is a high quality voltage. Generated AC power is applied to loads through the
static semi-conductor switches and output (load) breakers.
When maintenance or repair is needed, before the Input (CB1) and Output switches (CB3) are put
to the open circuit (OFF) position, the device must be switched to static bypass mode (please see
4.1.3.2). Consequently the maintenance switch (CB2) is put to the position closed circuit (ON).
After that first Output breaker (CB3), then Input switches (CB1) are turned OFF respectively.
2.1.1 Static Transfer Switch
Some blocks are named as “static switches” as can be seen above. These blocks consist of inverse
parallel connected thyristors. Controlled by the main board control unit (DSP) these switches
provide feeding of the loads through either mains or inverters. The loads are supplied through
inverter during the normal operating mode. Therefore, Inverter static switches are active if there
are no problems with the system.

SMART-LV SERIES 160 - 200 – 250 KVA PRODUCT DESCRIPTION
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
SMART-LV 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.

SMART-LV SERIES 160 - 200 – 250 KVA PRODUCT DESCRIPTION
2.2.4 Auto Restart Mode
In case of any failure of the mains, UPS will continue feeding the critical loads until the batteries
will reach the end of discharge voltage level. UPS will be working until the batteries are drained
and then will shutdown. When mains are restored to normal conditions UPS automatically will
start its operation, in the period determined by the user. UPS continues to operate in normal
(online) mode as long as the mains values are within desired limits. For SMART-LV Series, this
feature is not activated in the initial factory set-up.
2.2.5 Maintenance Mode
On the maintenance mode loads are switched to the maintenance bypass line with a breaker, so
that the UPS can be serviced without cutting off the power to loads. The breaker is in full
conformity with capacity of loads.
2.3 Battery Management
Lead-acid batteries are used.
Constant Charge Current
Constant current at 1/10 rate of the battery capacity is applied to battery, until it reaches the
float voltage.
Float Charge
Depending on the battery discharge current the 1/3 of the battery energy is charged at this level.
With this level of charging batteries are kept ready for use at maximum capacity. For lead-acid
batteries, this voltage varies between values 2.2-2.35 V/cell. This voltage may differ slightly with
temperature adaptation. Option of setting this coefficient is provided with our UPS, we
recommend using the temperature sensor.
Deep Discharge Protection
While the system is operating in the battery mode, if battery voltage has dropped below the
discharge level UPS shuts down and stops taking energy from the batteries. This value varies
between 1.6-1.75 V/cell for Lead-Acid batteries, and between 0.9-1.1 V / cell for Ni-Cd batteries.
Low Battery Warning
While the system operates on battery (stored) mode, according to actual loads, if the battery
capacity drops below 40% of its value, device will give audible and visible alarms. This value is
adjustable and can be set by user between 20%-70%.

SMART-LV SERIES 160 - 200 – 250 KVA PRODUCT DESCRIPTION
2.3.1 Advanced Functions (Battery tests) Auto Battery Test
The auto battery test discharges 10% of the battery energy in a user defined period. Default is 90
days. Test reports the battery condition as good, weak or replace. Results of the latest test can be
seen on the battery screen from the status menu.
WARNING: If the test result is “replace”, then batteries are completely
drained during the test. This may cause the interruption in the power
supply to the critical loads in case of the mains failure.
This test command can be given from front panel monitor, via TELNET interface, via RS232
smart communication or via UPSMAN (SNMP, see the options).
The purpose of the battery test is to check if the batteries can supply the minimum back-up time
needed in case of mains failure. We recommend checking the test results on the regular basis.
