6. Proposed Solution

UPS Offer:-

We are proposing Vertiv “Liebert® EXS (10 – 20kVA) Three-phase Stand-alone UPS”:

Liebert EXS is an optimized and integrated three-phase UPS solution with high efficiency power protection. The Vertiv™ Liebert® EXS UPS is designed for mission critical applications, such as Telecommunications, Transportation, Healthcare, Retail and Government Facilities. It brings exceptional features for mission-critical applications: its extraordinary double conversion efficiency up to 96.2% ensures remarkable operational cost savings. At the same time, with its unity output power factor and high power density, Liebert EXS is able to provide the utmost active power possible in a remarkable compact footprint.

System Description:-

The UPS includes the following operational components: Rectifier. Battery Charger. Inverter. Static Bypass Switch. Maintenance Bypass. Internal Battery (optional).

The UPS will automatically provide continuity

of electrical power, within defined limits and

without interruption, upon failure or degradation

of the commercial AC source.

The duration of autonomy (i.e. backup power time)

in the event of network failure is 1 hour as per HLC’s

request.

Features and Performances:

Output power factor up to 1. Double conversion efficiency up to 96.2%. ECO mode efficiency up to 99%. Compact footprint with multiple internal

runtime configurations. Available in 3/3 and 3/1 versions. Integrated maintenance bypass. Integrated input and output breakers/switches. Parallel capability for capacity and redundancy.

Liebert EXS offers integrated full galvanic isolation, meaning that an isolation transformer may be housed inside the UPS

6

cabinet. This greatly reduces the system footprint, thus providing space saving advantages.

The transformer may be connected to the input or to the output of the UPS, providing: Full galvanic isolation for medical and other critical applications. Installation with two independent input sources (with different neutrals). Installation in distribution without neutral.

The Liebert® EXS proposed UPS ratings and input/output configurations and System Key Features presented herewith:

RATING (kVA) INPUT OUTPUT

20 kVA 380-400-415V 3 Ph+N 380-400-415V 3 Ph+N or 220-230-240V 1 Ph+N

The single-line diagram of the UPS:-

Liebert EXS 20 kVA: Three-phase input / three-phase output

7

Liebert EXS 10-20 kVA: Three-phase input / single-phase output

Neutral Connection:

The Liebert EXS output neutral is electrically isolated from the UPS chassis. The input and

output neutral are solidly tied together; therefore the UPS will not modify the state of the

upstream neutral in any operating mode. As a consequence the neutral state of the

distribution downstream from the UPS is imposed by the mains and distribution switchgear.

Primary Input: The three-phase current taken from the commercial AC source is converted to a regulated DC voltage by the IGBT rectifier. In order to protect the power components within the system, each phase of the rectifier input is individually fitted with a fast-acting fuse.

The IGBT rectifier will provide DC power to the DC/AC output converter (IGBT inverter) and to the DC/ DC battery converter (booster / battery charger) when the UPS is working in “normal mode”. The latter will also boost the DC voltage to the correct level required by the Inverter when working in “battery mode”.

Operating Modes: The UPS inverter continuously supplies the critical AC load. The rectifier draws power from the commercial AC source and converts it into DC power for the inverter and the battery charger. The battery charger maintains the battery in a fully charged and optimum operational condition. The inverter converts the DC power into clean and regulated AC power which is supplied to the critical load (conditioned line). The static switch monitors and ensures that the inverter tracks the bypass supply frequency. In this condition any automatic transfer to the bypass supply (due to an overload etc.) is frequency synchronized and does not cause interruption to the critical load.

8

Electronic Static Switch (Bypass): The UPS comes complete with a Silicon Controlled Rectifier (SCR) static transfer switch rated to conduct full load current continuously in the maximum overload conditions.

The input feed of the bypass can be either the same as the rectifier or independent, provided they share the same neutral. The control logic will be managed by digital algorithms (using vector control techniques), similar to those used for the rectifier and the inverter, sensing the status of the inverter logic signals as well as operating and alarm conditions. If the bypass is within the specified synchronization window, the control logic will automatically transfer the critical AC load to the bypass source, after any of the following conditions:

Inverter overload. Output voltage abnormal. DC bus voltage abnormal. Parallel system transfer. UPS fault condition. End of discharge reached.

Operator Control and Display Panel: The operator control and display panel are located on the front of the UPS. The control panel of Liebert EXS includes a 320x240 pixel multi-lingual, graphic Liquid Crystal Display (LCD), allowing the user to operate and control the UPS checking parameters, as well as UPS and battery status and retrieve up to 2500 events/alarm logs for reference and diagnosis. Complete access to all LCD menus is possible through four software-assigned buttons located below the display. The on-screen icons above the buttons clearly explain the function of the button within each menu. Two LED indicators show the current working state of the UPS as described below.
