Shorter-Than-Expected UPS Battery Life Increases Maintenance Burden
A Case Study of a Manufacturing Company with Failed UPS
In the manufacturing industry, where digitalization and automation are progressing rapidly, the importance of UPS is increasing. However, regular maintenance is essential to ensure the safe operation of UPS.
A manufacturing company had installed multiple UPSs in its factory to prevent production line shutdowns in the event of a power outage. However, when a blackout occurred due to lightning, the UPS failed to provide backup power, and the production equipment stopped.
A Cause: Battery Drain in UPS System
An investigation revealed that the battery life of the UPS was shorter than expected. Large power surges occurred when large power-consuming devices in the factory were turned on, and the voltage in the factory dropped each time. As a result, the UPS frequently switched to battery backup mode, which caused the battery to wear out faster than expected.
In addition, the company was not managing battery replacement well, and sometimes the alarm would go off, requiring maintenance.
SANUPS E11B - Balancing Efficiency and Battery Life
To address the company’s needs, SANYO DENKI proposed a hybrid UPS called SANUPS E11B. This UPS switches between Economy Mode and Quality Priority Mode depending on the input power voltage. This energy-efficient technology prevents the battery from being worn out.
The UPS Input Range Advantage
In addition, the wide input range of the UPS helps to suppress battery usage even in environments with large power fluctuations.
The comparison of input voltage range between SANUPS E11B and Other Company
In addition to these benefits, the company also considered SANYO DENKI’s generous battery warranty. By registering as a free user, the warranty period can be extended from one year to three years.
The company soon adopted “SANUPS E11B” in its factory. After the installation, the company applied for a three-year warranty extension. As a result, the company is no longer concerned about battery failures or unnecessary maintenance.
The hybrid power backup system is SANYO DENKI’s original technology to ensure backup power without battery life concerns as well as providing energy efficiency.
