Reduce maintenance man-hours with Hybrid UPS and a 3-year battery warranty based on user registration

UPS battery life is shorter than expected, increasing maintenance burden

Company M manufactures and sells various production systems, industrial robots, and logistics-related equipment. The company had installed multiple UPS systems in its factories to prevent production line stoppages due to power outages and other reasons.
However, when a power outage occurred due to a lightning strike, the UPS did not provide backup power, and the production equipment stopped working. Mr. R from the Production Management Department wondered why the production equipment had stopped working even though we had installed a UPS, and began investigating the cause. He said the following:
"After investigating, we found that the cause was that the UPS battery was depleting more rapidly than expected, which meant that the battery ran out of power and the UPS was not supplying power during the blackout. After further investigation, we found that the factory equipment was also affecting the problem. When large power equipment in the factory was started up, a large current flowed for an instant, and each time it was started up, the voltage inside the factory dropped, and the UPS frequently switched to battery operation, which was causing the battery to drain faster than expected. This was a surprise, as I thought that power supply only switched to battery operation in the event of a blackout or something similar." (Mr. R)

There were also some problems with maintenance.
"The degree of battery depletion varied depending on the UPS, and we were unable to properly manage battery replacement. As a result, alarms would suddenly sound, and we had to perform maintenance every time this happened. Sometimes our production equipment had to be stopped. It took a long time to restart, which had an impact on production efficiency," says Mr. R.

A wide-range UPS minimizes battery consumption and reduces maintenance burden

Mr. R consulted with SANYO DENKI CO., LTD., a company with which he had dealings in other departments. After listening to the company's issues, SANYO DENKI CO., LTD. staff confirmed the range of fluctuations in the input power supply and proposed SANUPS E11B, Hybrid UPS that switches between Passive Standby and Double Conversion Online.

"The Hybrid UPS that they proposed reduces power loss by using Passive Standby when the power supply is stable, and automatically switches to Double Conversion Online in environments with large power fluctuations, achieving energy savings while steadily supplying high-quality power. What's more, because the UPS has a wide input range, it suppresses switching to battery power even in environments with large power fluctuations, preventing battery wear. This was expected to reduce the frequency of battery replacements and reduce maintenance work. It combines high reliability with energy-saving performance, so we decided that there were no problems with the specifications." (Mr. R)

By registering as a user, the battery warranty period can be extended from one year to three years.

In addition to these benefits, Mr. R also took notice of SANYO DENKI CO., LTD. 's generous battery warranty.
"A SANYO DENKI CO., LTD. representative explained that by registering as a free user, we could extend the warranty period from the usual one year to three years. The battery life is about five years, but if the battery unexpectedly deteriorates, they will replace it free of charge within three years. Most other companies only offer warranties of one or two years, so this option was very convenient. In addition, because we can receive email notifications six months before the battery reaches the end of its life, we can prevent fatal accidents such as forgetting to replace the battery and being unable to back up during a power outage, and we can also make maintenance plans in advance." (Mr. R)

Company M soon decided to adopt the SANUPS E11B and introduced it in its own factory.
"After installing the battery, we immediately applied for a three-year warranty extension. Now we don't have to worry about battery problems or unnecessary maintenance, which has made things much easier. We're grateful to SANYO DENKI CO., LTD. for the useful advice they gave us." (Mr. R)
