TACKLING ON-SITE POWER COSTS AT CRITICAL FACILITIES - DC UPS distributed throughout a critical infrastructure facility can reduce initial capital costs and lower overall O&M expenses

摘要

Uninterruptible power supply (UPS) issues are often solved at the facility level with unnecessarily large, inefficient, expensive and complex AC UPS systems. While this provides an easy demarcation between the facility and end equipment - with each focusing on a different part of the problem - it makes it difficult to determine overall operating efficiency and total cost of ownership. It also makes it hard to optimize performance.
