Company A is an independent system integrator that handles the construction and operation of various information systems and the sale of related equipment and software. Recently, the company received a complaint from a customer in the manufacturing industry and was struggling to respond.
Previously, Company A received a request from a customer to "introduce a UPS to the server in the factory while keeping costs down," and built a system. At that time, in order to keep costs down, they adopted an inexpensive "Passive Standby" UPS.
The system was installed over a holiday and the handover was completed without any issues, but when the factory started up on the following business day, it frequently switched to battery operation, causing alarms to ring repeatedly throughout the factory, causing some employees to complain of anxiety.
Upon receiving the complaint, Company A's support department hurriedly investigated the cause and found that the UPS detected voltage and frequency fluctuations and switched to battery operation because a large current flowed whenever the motor-based load of the factory equipment was operated.
In addition, frequent battery operation could cause the batteries to deteriorate faster than expected. The earlier replacement time would directly lead to a deterioration in cost performance," said Mr. E of Company A's sales department.
The customer scolded us for doing something about it right away. To solve the problem, we needed to replace the UPS with another one as soon as possible, so we worked with the support department to find a number of manufacturers. However, few could meet the short deadline, and even when they did, we couldn't find a product that could meet our requirements."
Put in a situation where he had to wait to respond to a complaint, Mr. E needed to get UPS to solve the problem.
In the midst of this, Mr. E remembered the "short-term delivery service" that he had previously been introduced to by a SANYO DENKI CO., LTD. sales representative, and decided to inquire about it.
SANYO DENKI CO., LTD. held a meeting with Mr. E that same day and selected the UPS.
"We found that Passive Standby UPS was sensitive to fluctuations in the commercial power supply and frequently switched to battery operation. Therefore, it was suggested that it would be effective to change to Double Conversion Online or Hybrid, which has a wider tolerance range for input power.
I was surprised to hear that the short delivery service includes a full line of 350VA to 5kVA Double Conversion Online and Hybrid, and that all of them can be shipped the next day." (Mr. E)
After testing each model, Mr. E chose the "Hybrid" because of its many benefits.
"The system automatically switches between three power supply modes - efficiency priority mode, active filter mode, and power supply quality priority mode - according to the state of the commercial power supply, achieving both the high efficiency of Passive Standby and the stability of Double Conversion Online. In addition, features such as the automatic battery check ensure reliability by ensuring reliable operation during power outages, which was the deciding factor."
In addition, Mr. E was also very satisfied with the long expected battery life.
"The battery life of the inexpensive Passive Standby UPS we had previously adopted was two to three years, but we found that the SANYO DENKI CO., LTD. UPS had a battery life of about five years, which is 2.5 times longer. It reduces the maintenance labor required for battery replacement, and is very efficient because it can be replaced when it's time to replace PCs and servers, which also occurs every four to five years. The initial cost is higher than that of Passive Standby, but we decided that this system had greater cost benefits in the long run." (Mr. E)
Thus, Mr. E decided to use the SANYO DENKI CO., LTD. Denki UPS, and was able to receive the UPS he selected two days after placing his order. Mr. E says:
"The customer was very satisfied. I was surprised at how quickly SANYO DENKI CO., LTD. could deliver, and I'm grateful that they had such an extensive lineup, which allowed us to get the optimal UPS. We learned a lot from this incident, such as the fact that using a high-quality, highly reliable UPS ultimately leads to cost reductions. From now on, we will make proposals to customers with a long-term plan in mind, rather than being swayed by short-term prices."
