Procurement of UPS for large scale projects is never like that of any common projects. The risk levels, system complexity and operational failure consequence would be much greater, in all aspect not limited to merely on the hardware’s equipment life cycle, particularly if you are dealing with Data center, hospital or essential facility. Choosing the right UPS partner can make your facility runs continuously and in good health. We should evaluate UPS vendors in three key areas.
Essential Certifications and Quality Standards for UPS Vendors
Certifications serve as an initial hurdle during the vendor evaluation process. However, certification levels can vary and must be carefully scrutinized. At minimum, we’ll require vendors to have an ISO 9001 certification to verify that the manufacturer operates under certified quality management processes and controls. Unfortunately, just having certification is meaningless if the certification’s scope excludes your production from the vendor’s ISO scope (such as, if vendor's ISO scope is only limited to “sales” and not “production,” they may not actually be manufacturer but instead trading company) .
For extensive jobs, determine whether providers can supply large range of qualifications. Most government-based as well as organizational jobs need either an ISO 14001 environmental administration certification or an ISO 45001 job safety and security and also wellness certification. Product details qualifications like CE, UL, and also TLC also offer third party evaluation to certify your products conform to the security and also performance criteria they promise. For jobs that will be deployed in different nations, CE qualification obtained through notified physique holds far more power than the maker’s self declaration.
Certification validity is the most effective check. Buyers can log in the China's CNCA website and look up ISO certificate's status and validity scope. The same, buyer can visit TLC certification center to verify the TLC certificate. Using simple login, we can find that certification has expired, certificate's scope is not suitable to product we required and we may find certificate belongs to the body which we have never heard.
Evaluating Manufacturing Capacity and Delivery Reliability
Certifications tell you about vendor’s plans, but manufacturing capacity tells you about vendor’s plans. For major project, production volume, quality processes and on-time delivery are good indicators of how reliable an OEM is.
The size of the factory and production lines gives an indication as to the vendor's capacity to deal with big orders. An optimized factory with automated production lines, in-house PCB assembly, and 100% aging test on finished products ensures reliable quality management. A R&D center, and an ATE test center are strongly recommended to ensure products are developed to your requirements.
Perhaps one of the most real-world indicators of supply chain reliability is the supplier’s on-time delivery record. The best suppliers will show an on-time delivery rate of 95 percent and beyond. This is particularly true on massive projects that will stall in construction if power equipment supplier falls behind schedule. Responsiveness is yet another clue-suppliers who consistently answer client emails and phone calls within two or three hours usually have their internal processes and communication lines more streamlined than their less responsive counterparts.
Reorder rates are extremely helpful for those that are shopping around from few different suppliers to gauge the happiness of current clientele. A reorder rate higher than 20% shows not only that current customers are pleased with your products but they continue to do business with you because of it. Reorder rates are not the end all be all for quality product but can be used.
Technical Support and Long-Term Service Capabilities
The supplier doesn't simply drop the equipment and walk away; when buying UPS system for large project the product alone means less than its support and service abilities. A failed UPS during the night and the public holidays 2:00 am is measured in minutes, not hours, to its supplier.
For large UPS systems procurement, the Factory Acceptance Testing (FAT) and the Site Acceptance Testing (SAT) are required. In FAT, the UPS is placed under full load using assistive loadbank and is subjected to various conditions (such as, Carrying the full load, switching to the batteries seamlessly, and transferring to the bypass). The UPS under witnessed test can uncover and eliminate many flaws and calibration problems at the factory, which ultimately saves installation time and cost. After delivery and installation, the UPS is again tested during the SAT.
It’s the same story with the spares inventory. Relying on the offshore manufacturer for replacement parts adds valuable lead time to each repair. Vendors with local spare parts inventory can reduce mean time to repair, and with remote monitoring capability, 24/7 vendor support can help prevent system issues, ideally shifting the maintenance from being reaction to prediction.
Conclusion
When you’re evaluating vendors for major UPS deployments, price is the easy part. Certifications come first, double check they are relevant to the type of projects you deliver and meet industry standards. Factory capacity and delivery reliability signal company’s ability to deliver at scale, examine their on time delivery records, and confirm the size and sophistication of their manufacturing operations. Ensure that they have adequate technical support and service resources to keep the equipment running throughout its lifetime. A UPS project the size of yours warrants an evaluation strategy to secure the long-term commitment of the right vendor.
