What is an Energy Saving UPS?
An Energy Saving UPS, also known as an Eco-friendly UPS or Green UPS, is a power protection device designed to provide seamless power backup while consuming less energy than conventional UPS systems. These UPS units incorporate advanced technologies and features that optimize their efficiency and reduce their carbon footprint, making them an eco-conscious choice for businesses and individuals alike.
How Does an Energy Saving UPS Work?
Energy Saving UPS systems employ several innovative techniques to improve their efficiency and save power. Let's explore some of the key technologies used in these eco-friendly UPS units:
High-Efficiency Design
Traditional UPS systems often suffer from energy losses due to inefficiencies in their design. Energy Saving UPS units are built with high-quality components and cutting-edge engineering to minimize these losses. They use highly efficient transformers, capacitors, and inductors to ensure that the energy conversion process is optimized.
Double Conversion Technology
Energy Saving UPS systems often utilize Double Conversion Technology (DCT), also known as Online UPS. In DCT, the incoming AC power is converted to DC, and then, through an inverter, it is converted back to AC power. This continuous conversion ensures a consistent and clean power output, protecting sensitive devices from power fluctuations and delivering higher efficiency compared to other UPS topologies.
Energy Monitoring and Management
Modern Energy Saving UPS models come equipped with sophisticated energy monitoring and management features. These systems track power consumption in real-time, allowing users to identify potential energy wastage and take necessary steps to optimize energy usage.
Eco Mode
One of the standout features of energy-saving UPS systems is the Eco Mode. When the UPS detects a stable input power supply, it switches to Eco Mode, bypassing the double conversion process. By doing so, the UPS reduces energy losses significantly, leading to enhanced efficiency during periods of stable power.
Automatic Voltage Regulation (AVR)
Energy Saving UPS units often incorporate Automatic Voltage Regulation (AVR) technology. AVR helps stabilize the output voltage even during minor fluctuations in the input power supply. By regulating the voltage levels, the UPS reduces unnecessary energy consumption and enhances the life of connected devices.
Benefits of Choosing an Energy Saving UPS
Opting for an Energy Saving UPS offers numerous advantages, making it a wise investment for both businesses and individuals concerned about the environment and their energy bills. Let's explore some of the key benefits:

Taking advantage of these programs can further offset the initial investment cost and accelerate the return on investment.
ECO mode
Choosing the right UPS mode for your needs can save you money and energy. You can choose from different modes for different needs, and you can even tailor them according to the location you are using the UPS. This way, you can make the most of your UPS while saving money on your energy bill. However, you should know that some UPS modes have limitations. For example, an UPS in ECO mode will not protect you from overvoltages, so it will not be able to protect your load in an emergency. Moreover, it may reduce the battery life and reduce fault clearing. Ultimately, you must decide whether you really need this feature.
Before you install an energy-saving UPS with eco mode, you must first determine the type of loads you have and which ones require uninterrupted power. Once you have identified the characteristics of your critical loads, you can then start tuning your UPS in ECO mode. This is important because the eco mode can affect transfer time and fault tolerance performance.
Boosting load factor
One of the ways to boost the efficiency of an energy saving UPS is by increasing the load factor of the unit. This will reduce the waste heat output and reduce the demand for cooling systems. However, this approach will reduce the reliability of the UPS. As a result, this technique is best used overnight.
In addition to increasing load factor, lowering the peak demand of your power system is also an efficient way to reduce your electricity bill. This can be accomplished by implementing scheduling techniques. For example, if you have 10 loads at different times, you can schedule them so that they are not always required at the same time. Alternatively, you can schedule high-wattage cooling equipment to reduce peak demand. This method can result in significant savings for large operations.
To boost load factor, you can also lower the energy efficiency of the UPS. For example, a 95% efficient UPS uses 95% of the original power input, but only uses 5% of it to operate. This means that a higher efficiency UPS consumes less energy and will have a lower heat output. On the other hand, a low-efficiency UPS will require more air conditioning to stay cool.
Static bypass path
Energy saving UPS systems use a static bypass path as a backup path in the event of a power failure. This path provides redundancy to the UPS inverter and prevents interruptions to the critical load during a power failure in the main power grid. A static bypass path also minimizes the possibility of a malfunctioning UPS by allowing the UPS to be bypassed during servicing.
Static bypass paths for UPS systems are usually external in design. They are connected to the UPS output and input and the raw mains power supply. They can be switched off for safe maintenance, and can be swapped out if necessary. An external static bypass path is not a good choice for energy-saving UPS systems unless you need a UPS with an external power supply.
Static bypass paths for UPS systems allow you to quickly switch from one power source to another. The UPS's inverter remains in standby mode during this time. When mains power fails, the UPS will quickly engage the inverter, which will automatically power the load. The efficiency of an energy-saving UPS with a static bypass path can range from 98-97%.
Efficiency ratings
Efficiency ratings are a useful indicator of the power quality of energy saving UPS systems. Typically, they are measured as a percentage of output power compared to input power. In addition, they indicate whether the energy efficiency of a UPS system can withstand a wide range of load conditions. The efficiency of UPS systems can be measured in kilowatts or watts depending on the load applied to them.
Energy efficiency is a critical factor to consider when choosing a UPS. An energy efficient UPS system can save a business hundreds of dollars over the course of its life. It can also reduce energy costs since its power consumption is more efficient. UPSs with higher efficiency ratings are also more cost-effective than those with lower efficiency ratings.
Most UPS systems are operated at less than 50% of their running capacity. If a facility wants to purchase a UPS that is more cost-effective, it must match its desired reliability with its actual requirements. Then, it must estimate the cost of downtime that could occur in the event of an emergency.
Disadvantages of ECO mode
In some cases, operating a UPS in the ECO mode can help you save money. However, this mode can have drawbacks, such as short interruptions in continuous power. These can cause your equipment to reset and take time to restore to normal operation. This is why many mission-critical sites and data centres do not choose to operate their UPS systems in this mode. Instead, they prefer to purchase modern UPS equipment that offers higher efficiency and continuous online protection. It is important to choose the right UPS mode for your application and evaluate its efficiency.
Another disadvantage of ECO mode is that it requires your UPS to detect a power failure before switching to the inverter. This process can take between one and sixteen milliseconds. This can cause a surge in your transformer and trip your circuit breakers. Furthermore, it can result in damaging harmonics. As such, ECO mode can cause your UPS to run inefficiently and cause power fluctuations.
Cost of ECO mode
Choosing the right UPS operation mode is crucial to maximizing energy savings. The UPS operation mode you choose will determine several factors, such as efficiency, TCO, input voltage operation range, transfer time, input or output protections, and UPS status. Efficiency ratings are not always indicative of real-world performance, so it is important to compare efficiency curves. A UPS that runs in ECO mode will use less energy, but may reduce reliability. It is also important to consider whether or not your application is critical.
The efficiency gains offered by ECO mode on an energy saving UPS are substantial, often ranging from 2% to 33%. This may sound like small savings, but in practice, this translates into hundreds or even thousands of dollars of energy savings each year. Further, the EPA grants UPS manufacturers a 25% efficiency allowance for UPSs that use ECO mode.
When an energy saving UPS enters ECO mode, it powers a load using the bypass path, which reduces the overall power consumption. A typical industrial UPS can operate up to 15 years, so even a 1% improvement can save considerable amounts of power. As a result, energy savings from ECO mode can contribute to the reduction of power consumption and CO2 emissions.
Comparison of ECO mode to online mode
The main difference between online mode and ECO mode in an energy saving UPS is the transfer time. Online mode requires the UPS to switch the load from bypass to inverter in less time. However, in the event of power outages, transfer times are still important for some systems.
Depending on the usage, an online UPS can be more efficient than an offline one. Offline UPS systems are connected directly to input AC power, which is more stable and does not introduce any instability. However, an unstable grid can cause frequent transfers to battery operation, decreasing battery life.
While the difference between online and ECO modes is small, some people find advanced eco-mode to be more energy-efficient than online mode. While ECO mode can save electricity, it also reduces reliability. Compared to online mode, advanced eco-mode offers a wider range of features.
