GENERAL FEATURES OF THE UPS UNIT

Alongside their excellent performance and reliability, the POWERLINE GREEN 33

LITE range of UPS units offers a number of other advantages which include:

 On-line operation using real double conversion, with sinusoidal output voltage

(with the highest quality VFI-SS-111 parameters).

 UPS input reactive power compensation – with tangible financial benefits

resulting from reduced bills for reactive power consumption.

 High short-circuit current which helps to achieve high selectivity of the

protection available for the power distribution lines.

 Hybrid operation mode – extending backup time (in BATTERY mode) by

ensuring power is supplied to the inverter concurrently from batteries and from the

power grid with poor/insufficient parameters - this is available for a specific range

of network voltage degradation (very wide input voltage window).

 Achieving high efficiency over a wide range of loads thanks to the use of high

quality components.

 Dynamic cooling management algorithm designed to allow adaptive

adjustment of the cooling system capacity to the current state of the UPS unit (to

minimize power losses and to reduce the costs associated with the demand for

cooling).

 The Intelligent Battery Management technology utilizes the advanced battery

management strategy in order to extend battery life and to optimize the charging

time and charging energy efficiency.

 Availability of the ECO mode – further improves the efficiency of the power supply

system (through the ability to differentiate between periods with varying degrees

of supply reliability).

 Scalability (extending) of the backup operation time thanks to the possibility of

connecting larger number of external battery packs to the UPS unit (optional).

 The scalability of the power supplied by the UPS.

 The Start-on-battery function enables the UPS unit to be started even if power

supply from the mains is not available (the so-called "Cold start” feature).

 Capable of operating in conjunction with external control panels (using the

Android system), and using a RS232, RS485 or USB communication interface,

SNMP/HTTP network management card, control inputs and programmable volt-

free outputs. It uses an integrated LCD operator’s control panel (with adjustable

angle). All these are designed to allow a customised UPS remote control

strategy.

 Remote Emergency Power Off (Remote EPO) functionality which interrupts

power supply from the UPS output to loads in extreme situations or in emergency

(e.g. fire).

 Obtaining information about temperature and humidity on the basis of

measurements – making it possible to analyse the environmental parameters.

 Events Log – records and stores the data related to the events that have

occurred during the operation of the UPS unit (recording the modes of operation,

alerts and messages related to the device).

 “Soft start” – ensures correct start of the UPS system (provides protection

against formation of transitional states).

The POWERLINE GREEN 33 LITE UPS systems consists of the following functional

blocks:

 rectifier,

 inverter,

 battery set,

 microprocessor-based control system with measurement circuits,

 automated by-pass system (static BYPASS),

 manual (service) bypass system (UPS/BYPASS manual switch) – optional

Figure 1: Simplified block diagram of the UPS unit

The rectifier transforms the alternating current voltage from the mains into direct

current voltage. It also doubles as a battery charger. The DC voltage bus is the basic

source of power for the inverter system which in turns generates sinusoidal AC

voltage to be used to power the loads. The microprocessor-based control systems

ensure precision and reliability of the entire power supply system.

The automated bypass system helps to increase the overall operating security of the

entire system. In cases where the permissible inverter parameters have been

exceeded, receivers will be supplied directly from the mains. In this way the

automated by-pass system works as an additional passive protection of the power

supply. The manual switching function for the bypass system allows switching over

completely to supplying power to the connected loads from the mains only. In this

way the connected loads are powered from the mains, thus bypassing the internal

UPS modules.

Duration of the power back-up operation depends on the number of loads as well as

the type and number of batteries used with the UPS. Please note that even in case

when batteries from different suppliers have the same rated capacity, the backup

time for the same load may vary.

 The electric system's grounding conductor leads the leakage current away from

the receivers. The leakage currents of all loads connected to the UPS unit's

output are totalized in the UPS unit's power lead. The summary leakage current

may trigger protective devices (RCD) and result in disconnecting power to the

loads.

 A UPS unit is a fixed connection device; consequently, a breaker should be used

in the fixed cabling.

 When connecting and disconnecting signal cables, all actions should be

performed with one hand only (if feasible). This is to avoid electric shock when

touching two surfaces with different electrical potentials.

 Connecting leads should be routed in such a way to ensure they are

protected against treading on them or tripping over them.

 An emergency power-off button (EPO), dedicated to the UPS system, should be

installed in the building's electrical system. This is to allow disconnecting, in

emergency, the UPS unit from the connected loads regardless of the mode in

which the UPS is operating.

 To minimise the risk of fire, connections should only be made to circuits (electrical

systems) whose rating is adequate for the connected loads, with properly selected

overcurrent protection. Additionally, the breaker should feature at least a 3 mm

insulating air gap.

C) Operation of the UPS unit
