Two major issues are driving use of UPS -Two major issues are driving use of UPS -
Growing Need For Power Growing Need For Power ProtectionProtection
Degradation Of Power QualityDegradation Of Power Quality Lack of investment in power infrastructure by
power utility companies.
Reduction in electrical network maintenance to reduce cost. This decreases the reliability of the power network
Onus onto the end user to provide performance requirements to suit their needs.
Growing Need For Power Growing Need For Power ProtectionProtection
Increasing Demand For Quality Power By Increasing Demand For Quality Power By The End UserThe End User
The use of microprocessor based equipment in day to day office business activities requires the continuous availability of quality power to avoid damage to critical equipment.
The use of microprocessor based equipment in manufacturing processes requires protection from outages to avoid unplanned & uncontrolled downtime.
Advantages of UPS PowerAdvantages of UPS Power
Protection Against Power Interruption Protection Against Power Interruption
The primary function of the UPS is to protect the downstream equipment from power fluctuations -
Sags or dips in voltage
Total absence of incoming voltage which can last milliseconds or minutes.

Rectifier Rectifier Rectifiers performance is typically qualified as 6 or 12 pulse. This determines the type of current reflected into the mains supply. A 12 pulse produces less “harmonic” or non linear current into the mains supply.
PWM IGBT Inverter PWM IGBT Inverter PWM stands for “Pulse Width Modulation”. This is the “State of the Art” inverter switching technology used to recreate the AC waveform from the DC supply.
The power module used in the inverter bridge is called an Insulate Gate Bipolar Transistor (IGBT).
Battery Design Life (Sealed Lead Acid)Battery Design Life (Sealed Lead Acid)The battery quality is determined by the “Battery Design Life”. Lower rated UPS systems (< 10kVA) use 5 year design life batteries.
Larger UPS systems typically use 10 year design life batteries and in some cases up to 15 years design life.

AdvantagesAdvantages
Continuous Regulation Of Output Voltage & Frequency
The load is supplied with conditioned power at all times.
Higher Reliability
UPS internal components are in continuous operation. The internal components are not in stand by operation to support the critical load.
DisadvantagesDisadvantages
Efficiency
There is a cost of ownership due to heat losses

AdvantagesAdvantages
Efficiency

DisadvantagesDisadvantages
Non-Regulated Output Supply
Direct mains supply exposes critical load to voltage & frequency variations
Lower Reliability

Higher reliability required and achieved due to duplication of all infrastructure to end equipment.
PurposePurpose
Facilitates transfer of output load UPS to an alternative supply source for UPS maintenance works or UPS replacement. Ensures no “LIVE” power is present on the UPS (OH&S).
Key FeaturesKey Features Make before break changeover facility
Interlock facility with UPS to inhibit transferring between two sources which are not synchronized.
Changeover switch can have 1-4 poles.
External Maintenance External Maintenance Bypass IntroductionBypass Introduction
Interlocking SystemsInterlocking Systems
Rotary Switches - Electro-mechanical via a solenoid or blocking relay which inhibits the rotation of the switch. A push button enables the switch to rotate and simultaneously transfers the UPS to static bypass
Mechanical Interlock which inhibits the rotation of the switch. A push button enables the switch to rotate and simultaneously transfers the UPS to static bypass during the transfer operation.
Circuit Breakers/ Switches - Mechanical inter-lock via two Fortress/Castell keys located in UPS output switchboard and a third key connected into UPS system transfer control. The changeover circuit breakers cannot be closed without the keys present.
