Keep the Lights On: Uninterruptible Power Supplies


With the predictions of an early and active storm season it’s worthwhile to give a reminder about Uninterruptible Power Supplies, what they are and what they can do for you to help keep the lights on. In an increasingly connected and digital world, power interruptions can bring productivity to a halt, disrupt critical operations, and even lead to data loss. Whether you’re a business owner, a home user, or a tech enthusiast, ensuring a reliable power supply is paramount. This is where Uninterruptible Power Supplies (UPS) come into play. In this blog post, we’ll delve into the world of UPS systems, exploring their importance, types, benefits, and how they work.

The Need for Uninterruptible Power Supplies (UPS)

Imagine you’re in the middle of an important video conference with clients from around the world. Suddenly, the power goes out, and you’re left scrambling to reconnect, potentially damaging your professional image. Situations like these highlight the importance of UPS systems. They act as a safety net against power disruptions, allowing devices to keep running seamlessly even during outages.

Types of UPS Systems

  1. Offline/Standby UPS: This is the most basic type of UPS. It switches to battery power only when the main power supply fails. While it provides protection against power interruptions, it offers minimal power conditioning and surge protection. These generally look like large power boards.
  2. Line-Interactive UPS: This type offers more advanced protection. It includes automatic voltage regulation (AVR) to provide consistent voltage levels and better protection against voltage sags and surges. Most UPS’s use this topology
  3. Online/Double Conversion UPS: The most advanced and reliable type, the online UPS constantly powers devices from its battery, while the incoming AC power is used to recharge the battery. This provides the highest level of protection against power fluctuations, noise, and spikes. If you are an audiophile then consider adding one of these to your equipment list. Far more useful than a power conditioner that makes many promises but in fact cannot help with may power issues.
Benefits of UPS Systems
  1. Continuous Operation: UPS systems ensure that devices keep running during power outages, giving you time to save your work and shut down systems properly.
  2. Data Protection: For businesses, sudden power loss can lead to data corruption and loss. A UPS safeguards against this by allowing systems to shut down gracefully, preventing data damage.
  3. Equipment Longevity: Fluctuations in power supply, including surges and sags, can damage electronic devices over time. A UPS provides clean and stable power, extending the lifespan of your equipment.
  4. Surge Protection: UPS systems often include surge protection, shielding devices from voltage spikes that can result from lightning strikes or other power disturbances.
  5. Uninterrupted Communications: In scenarios where communication is crucial, such as emergency services or critical infrastructure, a UPS ensures that communication systems stay operational.
How UPS Systems Work

At its core, a UPS consists of a battery, an inverter, and a charger. When the main power supply is available, the UPS charges its battery while also supplying power to connected devices. In the event of a power outage, the UPS detects the interruption and instantly switches to battery power through the inverter, providing uninterrupted electricity to the connected devices until the main power is restored – keep the lights on.


Uninterruptible Power Supplies are a fundamental component of modern life, offering protection against power disruptions that can have far-reaching consequences. From ensuring smooth business operations to safeguarding data integrity and preserving equipment, the benefits of UPS systems are substantial. By investing in the right type of UPS for your needs, you’re not only securing your devices but also maintaining your peace of mind in an increasingly unpredictable power landscape.
