Uninterruptible Power Supplies

An uninterruptible power supply (UPS) is a device that's easy to install and provides power to computers, servers, server rooms, and data centres during main energy failures, electrical surges, or unexpected power cutoffs. These devices include a battery that ensures power continuity to your computer system for a period sufficient to safely shut down software or save tasks before turning off the computer.

Different Types of UPS Systems

There are several types of UPS system solutions available from leading backup power suppliers:

Online UPS

A system of supplying power by converting AC input (utility power) to DC and reconverting it to stable AC by the inverter while constantly charging the batteries. Supplies power without momentary power breaks in the event of a power outage.

**Standby UPS **

A system where, normally AC input (utility power) is output as is to connected devices and when a power outage or abnormal voltage is detected, the inverter starts feeding using power from the batteries. In the event of a power outage, a few milliseconds of momentary break occurs in AC output.

**Parallel processing UPS **

While power from AC input (utility power) is supplied, the bidirectional inverter connected in parallel corrects voltage and absorbs noise. Because this is the online inverter (parallel) system, it has both high efficiency and high reliability.

**Hybrid UPS **

This system operates in three modes: double conversion mode, economy mode, and active filter mode. The UPS system automatically selects the power feeding mode to best suit the power situation and load conditions, allowing for seamless mode transitions without output interruptions. The double conversion mode is used under poor power conditions, while economy mode is preferred when conditions are favourable.

Uninterruptible Power Supply Pricing Explained

Here’s a breakdown of the factors influencing the prices of uninterruptible power supply:

• Power Capacity - Higher power capacity units cost more. Consider the needed capacity when you buy an UPS power supply to ensure sufficient backup.
• Backup Time - Longer backup times increase the uninterruptible power supply price, providing extended support during outages.
• Features - Advanced features like remote management or environmental monitoring also contribute to higher prices.
• Brand and Quality - Renowned brands typically offer higher quality and reliability but at a premium, impacting the overall uninterruptible power supply price.

Uninterruptible Power Supplies Applications

Uninterruptible Power Supplies (UPS) are indispensable in various sectors where power continuity is critical. Here are some key industrial applications of UPS systems:

1. Medical Facilities

UPS systems are crucial in medical settings to maintain the operation of life support and diagnostic machines, particularly during power fluctuations or when equipment is moved between rooms.

2. IT and Data Centres

To prevent data loss and protect sensitive equipment from power issues, UPS systems are essential in IT infrastructures and data centres, ensuring continuous operation and data security.

3. Emergency Services

For critical operations in emergency services, including 911 call centres and law enforcement agencies, UPS systems provide uninterrupted power supply to maintain essential communication and response capabilities.

4. Financial Institutions

Banks and financial organisations rely on UPS systems to prevent disruptions that could lead to data breaches or accessibility issues, ensuring continuous management of financial transactions and data integrity.

5. Secure Communications Centres

In surveillance and military operations, continuous power is mandatory. UPS systems support 24/7 operation, preventing any power loss that could compromise security activities.

How to Choose the Right UPS Device

Selecting the right UPS system involves assessing power needs, calculating the total watts required, and determining the necessary runtime to sustain operations during outages. Also, ensure the UPS has enough outlets to support all connected devices and consider space for future expansion. Choose between various models like tower or rack-mount, with modern lithium-ion options offering space efficiency.
