Uninterrupted Power Supply System
Mitigating the Risk of Power Interruptions
Unexpected power outages, surges, or fluctuations can lead to costly downtime, data loss, and equipment damage. But, with the wide range of emergency power supply systems (EPSS) available — each with unique features and benefits — it can be challenging to determine which solution best safeguards your business.
Our EGSA-certified emergency power technicians and engineers provide expert guidance on navigating your EPSS requirements to determine if you need an Uninterrupted Power Supply (UPS), Generator, or both.

Benefits of Uninterrupted Power Supply
UPS systems provide critical power backup during outages, ensuring continuous operation of essential equipment and preventing data loss.
Seamless Transition
In the event of a power failure, a UPS system provides a seamless transition to backup power, allowing your business to continue operating without interruption.

Equipment Protection
UPS systems safeguard your sensitive electronic devices from harmful power fluctuations, surges, and spikes, extending their lifespan and preventing costly repairs.

Continuous Power
A properly installed UPS system ensures your critical equipment and processes remain operational during power outages, minimizing downtime and data loss.

Uninterrupted Power Supply FAQs
Many facilities managers ask us why they should choose between an Uninterruptible Power Supply or a generator. While our blog covers this question in depth, here are a few FAQs about the advantages of uninterrupted power supply.
How Does a UPS Work?
A UPS is a battery-powered device positioned between utility current and the equipment that it powers. Containing sensor technology that detects dangerous qualities in utility current, it prevents equipment from experiencing the disruptive and potentially damaging effects of power outages, sags, and surges. Different models offer different service features and levels of power support.
What types of models are available?
There are six common UPS models:
- Standard Standby models switch equipment from utility supply to battery supply.
- Ferroresonant models contain a ferroresonant transformer that smooths the transition from utility supply to battery supply.
- Line-Interactive models contain a filter and tap-changing transformer that smooths the transition from utility supply to battery supply.
- Online models feature an inverter that uses utility current when transitioning to battery supply, providing true uninterrupted electricity.
- Delta Conversion models are online models that use an additional delta converter to enhance uninterrupted electricity.
- Double Conversion models are online models that use a rectifier/charger to monitor power for critical load applications.
When could a UPS replace a standby generator?
A UPS is used instead of a generator under two conditions: when a company requires electricity to be truly "uninterrupted" and when it does not need to power its facility for the duration of an outage.
Although industrial units can power entire buildings for extended periods, the units found in most buildings provide approximately 15 minutes of uninterruptible power supply service to critical components. If your building needs uninterrupted electricity for the duration of an outage, implementing a UPS in tandem with a backup generator is a wise choice.
How do I know what size UPS my building needs?
The VA (volts/amps) of any UPS should match the VA of the equipment it serves. Consult with an experienced electrical contractor or engineer to evaluate your building's load before you select a certain product.
Does a UPS require maintenance like a generator?
Yes. It should receive regular maintenance and testing to ensure correct operation. Testing intervals can be done monthly, quarterly, or at the very least semi-annually. Many companies choose to have it tested during breaker testing.
How much does the average UPS cost?
The cost of an Uninterruptible Power Supply System can vary greatly depending on factors such as capacity, type, features, and brand, with prices ranging from a few hundred dollars for small, standby units designed for home offices or personal computers, to tens of thousands of dollars for large, industrial-grade, double-conversion systems intended to support critical infrastructure in data centers, hospitals, or manufacturing facilities.
