Uninterruptible Power Supply System

An uninterruptible power supply system, also called an uninterruptible power source or UPS, is an electronic device that has batteries inside or connected to it to provide battery backup emergency power when the utility power source, or the mains, fails. The UPS provides near instantaneous protection against power interruptions with stored batteries that provide temporary power until a standby generator system takes over if needed. Santa Fe Power Solutions offers many types of industrial uninterruptible power supply systems and services.


Santa Fe Power Solutions offers uninterruptible power supply systems, including both single-phase and three-phase uninterruptible power supplies from the top brands.


A power distribution unit, PDU, is a critical piece of equipment designed with multiple outputs that distribute electrical power and is typically used in data centers.

Types of Uninterruptible Power Supply Systems

There are different types of uninterruptible power supply systems, and Santa Fe Power helps our customers determine the best type of UPS to support your commercial or industrial operations. Several factors must be examined when selecting the best type of UPS, such as the load size, whether a single-phase or three-phase output is needed, the voltage and amps, the critical operations of supported equipment, and UPS functionality required, as well as budgetary concerns.

There are three main types of uninterruptible power supply UPS systems:

The type of UPS system is defined by how the power moves through it.

Standby Uninterruptible Power Supply

A standby UPS is the simplest type of uninterruptible power supply system and one of the most common. We often see these battery backups that are about the size of a loaf of bread plugged in under a desk to protect computers against a sudden power outage. This type of UPS plugs into a normal outlet which is typically single-phase, 120 volts.  

Most residential homes are single phase 240 volts with the majority of standard plugs at 120 volts (15 to 20 amps), although large appliances such as furnaces and AC units are often plugged into 240-volt outlets and may range from 30 to 40 amps, controlled by the breaker.  A standby, or offline UPS, is the least expensive type of uninterruptible power supply, and the battery and all components are self-contained.

Line-Interactive Uninterruptible Power Supply UPS System

A line interactive UPS, also called buck and boost, includes a built-in transformer to boost the voltage if it is sagging to eliminate voltage fluctuations and provide conditioned power. A line interactive UPS can boost voltage without running on the battery to save battery life and is often mounted together on racks to support servers in IT applications. Rather than a standard plug, they often have a round plug that twists and locks and can support larger circuits such as 240v and 30 amp outlets.

Online, Double Conversion UPS System

The online double conversion uninterruptible power supply system is required in large single-phase and all three-phase applications. This type of UPS converts incoming alternating current (AC) power to direct current (DC) power and back to high-quality AC power free from distortions and voltage fluctuations, which commonly occur in grid power. Online UPS systems are more expensive and are hardwired directly into the breaker panel. This type of UPS system provides continual clean and pure power in the best possible condition and has the ability to boost power when required.

Santa Fe Power helps you determine the best type of uninterruptible power supply for your commercial or industrial application. We offer additional UPS cabinets and bypass cabinets to ensure continual power when UPS systems require maintenance, repairs, and replacement.

Santa Fe Power Solutions, Inc. offers critical power solutions with full system design, including UPS systems, generators, automatic transfer switches, and all components to ensure reliable, uninterruptible power. We provide nationwide standby power solutions, including quality equipment, service, maintenance, and repairs. Contact us with any questions and for assistance in choosing the best type of uninterruptible power supply system.
