Company T is a food manufacturer that produces processed foods. In response to the growing awareness of food safety in recent years, the company has decided to implement a strict quality control system and has introduced inspection equipment to its production lines that performs appearance inspections and foreign object detection.
However, an error occurred in the inspection equipment that was introduced. We immediately asked the equipment manufacturer to investigate, but no abnormalities were found in the inspection equipment itself. Mr. Y, the manager of the Production Management Department at T Company, looks back on the situation as follows.
"According to the equipment manufacturer, it seems that voltage fluctuations are probably caused by food processing equipment that uses motors, which in turn is causing errors in the inspection equipment. If the inspection equipment stops due to an error, work-in-progress products waiting for inspection will pile up, creating a bottleneck for the entire production line and significantly reducing production efficiency."
Faced with the urgent need to come up with a solution, Mr. Y began researching power supply measures.
Mr. Y, who had been gathering information on UPS, noticed SANYO DENKI CO., LTD. 's products. He immediately contacted the person in charge and discussed the problem he was having.
After hearing about the issues from Mr. Y, the SANYO DENKI CO., LTD. representative proposed SANUPS A11K Double Conversion Online UPS. This proposal strongly appealed to Mr. Y.
"When I think of a UPS with Double Conversion Online, I always imagine a highly reliable UPS that switches to battery power without interruption in the event of a power outage, but this proposal was a little different. Under normal circumstances, it converts AC input to DC and then converts it back into a stable AC power source using Inverter. Because of this, it can also deal with the voltage fluctuations that were an issue this time, and was apparently the optimal method." (Mr. Y)
Another key point is the wide input voltage range of SANUPS A11K.
"With a UPS, if the power supply voltage exceeds the input voltage range, it switches to battery power supply, and the more frequently this happens, the shorter the battery life will be. We found that when the factory was operating at full capacity during busy periods, the voltage would drop to below 70V when the start-up timing of processing equipment equipped with motors overlapped. With a normal UPS, the input voltage range is ±15%, so it would immediately switch to battery power supply, affecting battery life. However, SANUPS A11K has a wide input voltage range of -40% to +20%, so another benefit was that it could prevent battery wear even in an unstable power environment." (Mr. Y)
Mr. Y, excited by these benefits, decided to adopt the UPS "SANUPS A11K" and installed it in his factory.
"Another key point was ease of maintenance. If there is an abnormality in the power supply, it can be immediately checked on the LCD screen. The battery and Inverter are modular, so they are easy to replace, and by switching to maintenance bypass, the battery and Inverter can be replaced while continuing to supply power." (Mr. Y)
Mr. Y had this to say about the introduction of UPS:
"We realized that the installation of a UPS is essential even for a small- to medium-sized factory like ours. We are grateful to SANYO DENKI CO., LTD. for selecting the optimal UPS for us. We would like to consult with them again if we need anything."
