Company B, a machinery trading company, supplies machine tools and other products to Japanese manufacturers in Southeast Asian countries. Company B is supplying machine tools and other equipment to Japanese manufacturers operating in Southeast Asian countries. Mr. D, the general manager of the Overseas Business Department, explains the situation as follows
In Japanese-affiliated industrial parks, the same power supply specifications as in Japan have been installed, and many Japanese equipment is in use. However, the power supply situation in Southeast Asia is more unstable than in Japan, and power problems such as power outages and momentary power loss occur frequently. In the heating and precision machining processes on the production lines of factory complexes, momentary power problems can lead to processing defects. In the worst case scenario, smoke or fire may also occur."
Company B then proposes to install a UPS (Uninterruptible Power Supplies) to provide a stable power supply, but the manufacturer's representative is reluctant to do so.
Despite the factory's high degree of automation, the only measures taken to deal with power problems were line monitoring by personnel who would deal with sudden power supply malfunctions. Although we knew that UPSs existed, we had given up on the idea of installing them on our production lines because of the operational costs associated with power consumption." (Mr. D)
While continuing to gather information, Mr. D visited SANYO DENKI CO., LTD. 's booth at an exhibition and discussed these issues. Later, a SANYO DENKI CO., LTD. representative visited Company B, discussed the details, and proposed the "SANUPS E23A" with Parallel Processing.
"SANUPS E23A that was proposed to us normally supplies commercial power, and the moment it detects a momentary drop or power outage, it switches to Inverter power supply. Unlike Passive Standby, it does not use a switch to switch, so in the event of a power outage, it switches without any interruption. This means we can recommend it to customers who place a high priority on power stability, such as in precision machining." (Mr. D)
"The UPS we've introduced up until now have been Double Conversion Online. I was surprised to see that by switching to Parallel Processing, SANUPS E23A, power consumption was reduced to about one-third. I didn't realize there was such a big difference depending on the UPS power supply type. I think this will also significantly reduce operating costs. In addition, the fact that it can suppress harmonics(*), which can cause other equipment to malfunction, means I think we can offer our customers something extra." (Mr. D)
*Harmonics: Current distortion generated by motors and other devices that adversely affect power lines and connected equipment.
Mr. D immediately went to the site together with a representative from SANYO DENKI CO., LTD. and gave a presentation to the customer.
"Our proposal was a perfect fit for our customer in a Japanese industrial park, so we received a formal order very quickly. For our company, it was a great benefit to have the lineup of products we could propose increased. We look forward to asking SANYO DENKI CO., LTD. for their continued cooperation in various ways in the future." (Mr. D)
