UPS (UNINTERRUPTIBLE POWER SUPPLY) CONCEPTS:

Telecom Network

Electronic systems such as computer networks, management systems and security systems are essential tools to ensure the business continuity and make your organization run smoothly and effectively. Telecom sector is one of the fastest growing in the economy, expanding at an annual average of 22 per cent over the last few years with cellular phone connections alone growing at 100 per cent. The country’s revenue from this sector will cross US$ 30 billion by 2013, according to a global information technology research firm. According to Gartner, the telecom subscriber base is expected to cross 770 million connections by 2013, growing at a CAGR of 14.3 per cent from 452 million in 2009. Means day by day it's very fast growing sector so it is also important to provide the reliable network to the customer. A major important role of UPS in telecom sector to provide the reliable network.

Behind every smoothly running telecom setup and wireless network, there should be a reliable power infrastructure. The telecom sector has been experiencing skyrocketing demand for new wireless products, and in the scramble to meet these demands, there has been a massive demand for backup power solutions.Power backup sources that satisfy multiple requirements—reliability, flexibility, durability and cost effectiveness.

In fact, we depend on stable and reliable electric power supply to live our lives; however, unfortunately, power supplies worldwide are unreliable. According to study, computers are subject to an average of 128 power disturbances a month. This means that computer systems and their files and applications, such as email, financial information, working documents, photos, music and all kind of records are at risk more than four times a day!
 UPS systems in Telecom Network:

A UPS system is the major backup solution in the telecom sector—from the changeover time till direct generation takes over. The requirement for UPS systems in the telecom sector can be broadly differentiated into two categories—active and passive. In the active IT category, power backup systems are required for mobile switching centres (MSC), base station controllers (BSC) and tower sites. The UPS rating for these requirements varies. For MSCs, the UPS power requirement is in the range of 120-160 kVA; for BSCs the requirement is for up to 40 kVA; and for towers, it is up to 10 kVA. Also, small rating UPS systems of 1-2 kVA are required for the tower, which are generally installed onto the tower itself. For passive IT application areas, the size of UPS system required is bigger—400-600 kVA. Apart from these, AC and DC UPS systems are also required for mobile equipment. Energy management for outdoor and indoor telecom BTS sites are vital applications.
The idea behind a UPS is pretty obvious from the name; in addition to filtering, enhancing or modifying the utility power, special circuitry and batteries are used to prevent equipments from losing power during a disruption (blackout) or voltage sag (brownout). These units are called different names depending on their typology design, but all fit into the general category of “backup power”.
Types of UPS systems required in Telecom Network:
The type of UPS systems and other power backup solutions that are required in the telecom sector depend on the requirements and applications of the network. The typical UPS configurations that are required are an MSC of 40-160 kVA; data centre UPS systems of 40-240 kVA; CSC of 1-20 kVA; and UPS systems of 1-200 kVA for offices and other purposes. As telecom sites also face power shortages, especially in rural areas, inverters ranging between 3-15 kVA are extensively deployed for shelter applications to ensure power continuity.

In mobile towers, operators are more concerned about power saving aspects. Each tower has a transmitter, power supply related equipment, air conditioner, generator, etc. UPS vendors critically examine the power saving aspects of these power gadgets. This is a critical function, which is linked to other important functions of the mobile service, which are monitored by TRAI.
Some new in this Segment:
Delta has introduced Delta Ultron DPS. Delta Ultron DPS series is a double conversion, IGBT rectifier three phase UPS, incorporated with state of art triple level inverter (TLI) topology. Ultron DPS is a new benchmark of data centre backup power solution, featuring high efficiency of up to 96 per cent in double conversion mode or up to 99 per cent in eco-mode.

Emerson has recently introduced its Chloride Trinergy UPS range, which is a dynamic ‘three mode operation’ solution that delivers up to 99 per cent efficiency.

Emerson also offers the NX and ADAPT UPS series, which suit all requirements due to their low footprint and high efficiency. “These systems are based on adaptive architecture.

Socomec offers Modulys Green Power UPS systems that range from 20-240 kVA.  Modulys Green Power is an online three phase double conversion UPS system, with high power density.

Socomec also offers the NeTYS RT online UPS range (rack mountable), ranging from 1.1-11 kVA, with double conversion technology.

Su-Kam offers the Static Bypass Switch, which takes two sources of power at the input and monitors them continuously to provide the better of the two available power sources to the electrical load connected at the output. 

Su-Kam also offers the Sinclair i Series, which provides safe and break free power for devices with very high efficiency and built-in batteries. It is highly efficient in both the mains mode and battery mode, with an extra wide input voltage window.


A generator can not substitute a UPS because, in the event of a disturbance in the power supply, there will always be a gap between the power supply failure and the generatorfiring from the "standby" state. This disruption in power supply could result in significant financial losses and justifies the need for a UPS.

A UPS differs from an auxiliary or emergency power system or standby generator, which does not provide instant protection from a momentary power interruption, as a UPS can be used to provide uninterrupted power to equipment, typically for 5–15 minutes until an auxiliary power supply can be turned on, utility power restored, or equipment safely shut down.

While not limited to safeguarding any particular type of equipment, a UPS is typically used to protect computers, data centers, telecommunication equipment, surgical operating rooms or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious business disruption or data loss.

A UPS not only provide protection against all types of power supply failure, but also are able to filter a wide range of issues encountered in the electric power supply, thus providing more sensitive loads with a clean power supply.

In short, the uninterruptible power systems perform two functions:



·  Filter disruption of the supply network.
· Provide power to the loads in case of mains failure.

UPS units are used to correct various common power problems, such as:
Power failure
Voltage sag
Voltage spike
Under-voltage (brownout)
Over-voltage
Line noise
Frequency variation
Switching transient
Harmonic distortion
