Time to Review Your UPS Protection

Retailers rely heavily on IT to provide services such as online shopping, EPOS systems and data processing. This reliance on IT has led to rapidly increasing power requirements and increased costs. However, the author explained that huge energy savings can be achieved by improving the efficiency of the UPS system.

Personal relationships with customers mean that the retail industry has higher expectations for its environmental performance than many other industries. While these are met in the workshop through the design of low-energy stores and environmentally-friendly product purchasing and recycling programs, energy and emissions targets are the main challenges facing the company’s upstream sector.

The driving force behind new technologies to reduce power consumption and emissions is key to the development and adoption of modern Uninterruptible Power Supply (UPS) solutions that can significantly increase efficiency and reduce carbon and physical footprints.

Since 2003, IT energy consumption per server rack has increased by 400% and continues to grow almost exponentially. Attempts to use traditional stand-alone UPS systems to meet future requirements can result in over-specifications, resulting in a wasteful gap between the installed capacity and the actual size of the critical load, and the inefficient use of expensive floor space . However, today’s modular rack-mounted systems can be sized by inserting or removing “hot-swappable” modules so that power can be increased as demand grows without losing space. The load of traditional independent parallel redundant systems is usually less than 50%, while the load of modular solutions is usually 70% or higher. This lowers the costs of energy and UPS cooling.

Transformerless UPS technology has also made a significant contribution to improving energy efficiency. For example, the new three-phase UPS system has intelligent energy management features designed to reduce energy consumption, reduce carbon dioxide emissions and minimize space requirements. Compared to the equivalent stand-alone UPS system, they can reduce the total physical footprint of the equipment to 0.41m² (maximum 100kVA) and 0.64m² (maximum 200kVA), providing industry-leading power density, up to 250kW / m² in operation Cost savings equal to electricity and cooling costs can be achieved within a few years.

Reasonable scaling and flexible growth are the keys to maximizing UPS efficiency. In addition, regular inspection and maintenance also play an important role after installation. For example, Tesco uses its UPS suppliers to preventively maintain high-power UPS systems to protect the data centers of its power distribution network. Regular maintenance can not only ensure that such UPS units support 24-hour IT availability, but also help optimize their efficiency. Throughout the life cycle of the system, proper component calibration and monitoring / replacement can save enormous amounts of energy – this is an important contribution given the challenge of balancing ever-increasing IT power requirements with cost control and environmental goals.

In addition to large-scale power protection in corporate offices, power distribution centers and data centers, UPS systems can also meet the needs of different stores. A trade-in program from Waitrose has progressively replaced existing UPS facilities in its supermarkets with new small UPS systems, providing flexible and easy-to-maintain support for its EPOS system. The compact modular UPS configuration can achieve cost-effective output expansion and redundancy in a small footprint, and reduce operating costs through high operational efficiency and near uniform power factor.

With scalable architecture and energy-saving technologies, modern UPS systems of all sizes can ensure the highest level of power protection for critical loads, while meeting the demands of retailers to build and operate energy-saving and environmentally friendly IT infrastructure.

Power Protection Case Study: Power Outage Successful. Many well-known retail chains in the UK have outsourced their IT infrastructure and data processing work to Retail Assist Ltd, a leading retail solutions and services company. UPS and backup generators can protect the power supply of Retail Assist’s critical systems.
