Company G, a semiconductor manufacturer, has installed UPSs in its factory to protect against power outages and instantaneous power loss. Mr. D, the factory manager, says, "In the clean room, all work processes are fully automated.
In the clean room, all work processes are fully automated. Therefore, even if some of the equipment stops working, it will affect the production of the entire factory. We have installed UPSs to prevent power outages, but our factory is designated as a designated energy management factory, and we are required to reduce power consumption. In order to reduce power consumption, we needed to address the power consumption of the multiple UPS units."
Under these circumstances, we were selecting a UPS that was due for replacement. We were also concerned about daily maintenance. We had noticed that the batteries were running low during our regular battery checks. At that time, we quickly replaced the battery and it did not cause any problems, but we were concerned that we did not know in advance when to replace the battery. (Mr. D)
Mr. D was looking for a UPS that could solve these problems.
*Instantaneous voltage drop (instantaneous voltage drop): A phenomenon in which voltage drops for 0.07 to 2 seconds due to a breakdown of transmission lines, etc.
Mr. D, who had been gathering information about replacing UPS, contacted SANYO DENKI CO., LTD. which had previously used the system at another factory, and consulted them about the current phenomenon.
After listening to Mr. D's detailed explanation of the situation, the SANYO DENKI CO., LTD. representative proposed the SANUPS E23A, which uses Parallel Processing, as the most suitable UPS for the company.
"After listening to their explanation, we learned that Parallel Processing has a higher power conversion efficiency than Double Conversion Online UPS we are currently using. The proposed SANUPS E23A has a conversion efficiency of 97% and consumes one-third the power of our current UPS, so we can expect significant energy savings." (Mr. D)
The person in charge explained that SANUPS E23A has a function that automatically checks the battery life. "With this function, we can prevent problems caused by battery deterioration in advance. Because it automatically performs battery checks, there is no need to arrange for an operator, which leads to time and cost savings. This gives us peace of mind in the unlikely event of a power problem," said Mr. D.
Based on this proposal, Company G soon decided to adopt SANUPS E23A.
"Because this UPS was made to order, it was also appealing that we could freely specify the battery manufacturer and type. Also, by customizing the battery panel, we hope to be able to save space and make the layout easier. We look forward to asking SANYO DENKI CO., LTD. for more help in the future." (Mr. D)
