UPS System Sizing: What You Need To Know

As the demand for uninterrupted power continues to grow, so does the importance of proper UPS system sizing. To choose the best UPS system for your needs, it is important to understand both the basics of how UPS systems work, and how to properly size a UPS system for your specific business requirements.

UPS systems are designed to provide clean, uninterrupted power to sensitive electronic equipment by filtering out disruptive line noise and voltage fluctuations. A UPS system typically consists of a battery, charger, and inverter all housed within a single unit. The battery provides backup power in the event of a power outage, while the charger ensures that the battery stays charged and ready for use. The inverter converts the DC power from the battery into AC power.

To ensure that your UPS system can provide enough backup power for your equipment, some factors should be considered when sizing a UPS system, including:

• The total amount of wattage required by the equipment to be powered by the UPS
• The length of time that backup power will be required
• The number of outlets needed
• The type of batteries used

Advantages of a UPS System

There are many advantages of using a UPS system, including:

• Increased power quality and reliability: A UPS system provides clean and regulated power, which can help to improve the overall quality and reliability of your power supply. This can in turn help to reduce downtime and increase productivity.
• Protection against power surges: A UPS system can provide protection against voltage spikes and other power surges, which can damage equipment or cause data loss.
• Improved energy efficiency: A UPS system can help to improve energy efficiency by regulating the power supply and providing condition monitoring capabilities. This can help to reduce energy costs over time.

What Type of UPS Do You Need?

1. Standby UPS System – Voltage & Frequency Dependant (VFD) – A standby UPS System switches to battery backup power when it detects a problem with the power supply such as a mains failure or voltage surge. When incoming power from the mains supply drops below or surges above safe voltage levels, the UPS System switches to DC battery power and then inverts it to AC power to run connected equipment.
2. Line Interactive UPS System – Voltage Independent (VI) – This type of UPS System works the same as the Standby Type but has an AVR incorporated to smoothen out ripples in voltage before supplying the load
3. Online Double Conversion – Voltage & Frequency Independent (VFI) – A double-conversion UPS System provides consistent and clean power regardless of the condition of incoming power. Double Conversion UPS Systems provide a stable source of power as they operate on isolated DC power 100 percent of the time and have zero switch-over time.
