2General Description
2.1 Introduction
Congratulations on your purchase of the PW1000 1-3kVA UPS.
High reliability, low operating cost and excellent electrical performance are just some of the highlights of this innovative
UPS solution.
Uninterruptible Power Supplies Ltd. specialises in the installation and maintenance of Uninterruptible Power Systems; and
this UPS is just one example of our wide range of state-of-the-art power protection devices that will provide your critical
equipment with a steady and reliable power supply for many years.
2.1.1 Advanced design features
By using the latest technological developments in power engineering, the PW1000 1-3kVA represents a new generation of
transformerless UPS-System. Its advanced double conversion Voltage and Frequency Independent (VFI) topology
responds fully to both the highest availability and environmentally friendly requirements, compliant with IEC 62040-3 (VFI-
SS-111) standards. A full UPS specification is provided in Chapter 8 of this manual.
Following, are some of this unit’s advanced design features:
• True online technology continuously supplies your critical applications with stable, regulated, transient-free pure
sine-wave AC power.
• High-Frequency Transformerless technology and tower-convertible enclosure enables the UPS to be integrated
into even the most difficult environments with space constraints.
• User-friendly design that permits simple and trouble-free installation. All units are supplied with input and output
power cables as standard.
• Smart battery management system which extends the battery life span.
• Highly efficient PWM sine-wave technology yields excellent UPS efficiency. The high crest factor of the inverter
handles peak inrush current loads and so avoids a need to upgrade to a UPS with a higher power rating.
• Compliant with various stringent international EMC standards for electromagnetic interference & protection.
• Selection of output voltages (200/208/220/230/240) available to match the UPS to local supply specifications or
specific load voltage requirements.
• A selectable bypass voltage tolerance (low/high sensitivity) restricts the range of voltages that can be applied to the
load when the UPS operates on bypass. The ranges are ±15% (low sensitivity) and ±10%V (high sensitivity). For
example, if the output voltage setting is 230V the bypass sensitivity Low range is 230V ±15%.
• Selectable 50Hz or 60 Hz operation.
• Fully digitized control logic for better functionality and enhanced power protection. Digital signal processing (DSP)
also provides efficient communication capabilities for enhanced remote control and monitoring flexibility.
• Active power factor correction (PFC) control function constantly maintains the UPS input power factor to >0.99 at
100% load, with resulting outstanding energy efficiency.
• Wide input voltage tolerance, from 110V~300V, allows the UPS to operate normally without draining the battery
unnecessarily during significant mains voltage dips, which helps extend the battery service life.
• DC-start function permits the UPS to be started during a utility power failure if required.
• Overload protection system automatically switches the UPS to bypass mode if an overload occurs and
automatically switch back to inverter mode once the overload condition ceases. Should the output become short-
circuited, the UPS puts the system in stand-by mode, provides visible and audible alarms, and turns off the output
supply automatically until the short circuit situation is resolved manually.

2.1.2 PW1000 1-3kVA Model range
The PW1000 1-3kVA UPS range comprises 1 kVA, 2 kVA and 3 kVA models, each of which is designed as a self-
contained UPS comprising a rectifier, battery charger, inverter, static switch and battery pack. All the models in this range
are easy to install, and supplied with suitably terminated power cables.
The PW1000 1-3kVA operates as a stand-alone UPS module and can be mechanically configured as a floor-standing
tower unit or installed in a standard 19 inch rack. An accessory pack which contains all the parts necessary to configure
the unit for either type of installation is supplied with the UPS.
Optional external battery cabinets are available to increase the UPS autonomy time. The battery cabinet design
compliments the UPS cabinet and the two cabinets can be mechanically connected together to form a single unit when
installed as a tower system – see chapter 3 (Installation) for mechanical configuration details.
2.2 UPS Operating principles
2.2.1 Basic block diagram
Figure 2.1 UPS Functional block diagram
EMI Filters
The UPS has an input and output EMI filter to reduce the effects of electromagnetic noise generated by the UPS on other
adjacent equipment – e.g. reduces external radio interference.
Battery charger
A regulated battery charger, power from the AC Input supply, charges the battery whenever the input supply is available.
DC/DC Boost converter
In times of AC Input supply failure, the DC/DC Boost Converter turns on and boosts the battery voltage to a level suitable
for use by the inverter. It provides a regulated DC output for the inverter while the battery voltage decays during discharge
and includes voltage and current monitoring and overload protection.

2: General Description
AC/DC Converter
As its name suggests, the AC/DC Converter converts the AC Input supply into a controlled DC supply that is suitable for
use by the inverter. The converter uses a leading-edge switched-mode technique which produces an input power factor of
almost unity over its full operating range (0.99 at full rated linear load) and thereby maximises the UPS efficiency.
The converter can satisfy the inverter DC power demands over an AC Input voltage range of between 110V~300V which
means that the battery is not called upon during power dips (brownouts), thereby maximising battery life and availability.
DC/AC Inverter
The inverter converts the DC voltage connected to its input, from the AC Input supply via the AC/DC converter or from the
battery via the DC/DC converter, and produces a regulated AC Output voltage that is suitable to power the connected load
equipment. The control logic associated with the Inverter power block is substantial, and in addition to the controlling the
output sine wave voltage it also provides various levels of overload protection, frequency regulation and synchronisation,
and output voltage error detection.
Static switch
The static switch provides a means of connecting the UPS AC Output (load) to the inverter output or the bypass line,
which is connected directly to the UPS AC Input. The control logic within this power block will transfer the load to the
bypass supply in the event of overload or UPS (inverter) malfunction. The load can also be transferred between the
inverter and bypass line manually if required. Note that a controlled transfer can take place only if the inverter and bypass
line are synchronised in frequency and phase.

2.3 Operator control panel
The UPS is controlled from the operator control panel located on the front of the unit.
The user-friendly UPS control panel comprises three areas:
Figure 2.5 Operator control panel
2.3.1 LED Indicators
Input mains supply status
This led is permanently ON if the mains supply is within in the normal operating range of 160~300 VAC, and
flashes if the supply falls to 120~159 VAC. If the led is OFF it indicates a mains supply failure.
Programmable outlet status
The programmable outlets are normally connected to less critical loads which can be shed when the utility
power fails. This reduces the load on the battery as it discharges and thereby increases the back-up time for
the more critical loads which are connected to the unswitched UPS outlet(s). The indicators are permanently
ON when the outlets are live.
Bypass supply status
This led is permanently ON when the UPS is operating in the ECO mode and flashes when the load is
transferred to bypass – either manually or due to a detected fault.
UPS fault indication
This LED illuminates to indicate the presence of a fault condition within the UPS that needs attention. It is
usually accompanied by an audible alarm.

2.4.1 Communication Ports
Several communication options can connected to the PW1000 1-3kVA. These are described briefly below with further
details provided in Chapter 7 (Options).
USB port (Figure 2.7 item 3)
A USB type B socket is provided to allow the UPS to be connected to a PC using a standard USB peripheral interface
cable. The USB communication protocol complies with USB version 1.0 (1.5 Mbps) and USB HID version 1.0. This facility
can be used in conjunction with UPS monitoring and shut down software (not supplied).
RS-232 Interface port (Figure 2.7 item 2)
The RS-232 port allows the UPS to be connected to a PC and provides the same functions as the USB port.
Emergency power off (EPO) (Figure 2.7 item 1)
If an external emergency power off (EPO) facility is required, the external circuit must be connected to the two pin plug
located on the rear panel. A plug-in connector with screwed terminal connections is supplied ready fitted to the EPO
socket to simplify the connection of the external cable if the UPS is located in a confined space, such as when it is rack
mounted. The EPO input requires a normally-open contact which closes to active the EPO function. If the UPS is shut
down by the EPO input (closed), it has to be restarted manually after the EPO input is removed (opened).
Optional interface cards (Figure 2.7 item 4)
An optional SNMP/ CS141 interface card can be fitted in the card slot to enable the UPS to be integrated into a network
monitoring and control system.
ON BYPASS
This mimic is displayed if the UPS develops a fault, or is overloaded, whereupon the
LOAD is transferred to the bypass line and connected directly to the utility supply
(INPUT). The battery will remain on charge if the UPS battery charger is healthy.

3Installation
3.1 Unpacking the UPS equipment
The manufacturer has designed robust packaging for your product to help ensure it reaches you in good order; however,
accidents and damage may sometimes occur during shipment. You should inspect the UPS carefully upon receipt and if
there are signs of damage you must inform the carrier and dealer immediately.
Save any recyclable packaging for re-use or dispose of it appropriately and correctly.

2. Check the package contents. The standard unit includes:
a) User Manual.
b) IEC output cables (for UPS with IEC sockets only).
c) IEC input power cable (for UPS with IEC sockets only).
d) A UPS accessories kit which allows the UPS to be configured for Tower or Rack installation.
3. Before proceeding, check the data plate on the rear of the UPS and verify that the unit’s voltage and power ratings
comply with the equipment order details. Contact the dealer immediately if this is incorrect.
3.2 Selecting a suitable installation location
As the UPS weighs several kilograms, the location where it is to be installed must be able to safely support its weight.
To ensure correct operation and a long service life, always install the UPS in accordance with the following environmental
standards:

temperature must be maintained at 20°C to ensure its lifespan is not reduced
• The UPS is not designed for outdoor use
• The installed location must be clean, dry and free of excessive dust
• The UPS must not be installed in a corrosive environment or in the vicinity of flammable items
• The ventilation grills at the front of the UPS and extractor fans at the rear of the UPS must not be obstructed
• The UPS equipment must be installed with the clearances illustrated in Figure 3.2 as a minimum
CAUTION: Read the safety information contained in chapter 1 before installing the UPS.
