The Real Cost of Power • The lure of commoditized power? – Low cost /disposable products • Real MTBF and MTTF and efficiency have a $ impact – Hidden costs of high failure/replacement rates • UPS - service calls for battery replacement or other battery remediation are a sizable hidden cost of ownership – The “Dirty power” secret • “Dirty Power” causes more downtime and lost production than power reliability incidents • Often can’t be detected or prevented by typical defenses 3

The Real Cost of Power • What is the real cost of failure? – Take into account the true inventory/replacement cost (product/labor) – Do you understand impact on related assets – will sensitive controls be damaged? – Know your true dollar value for uptime and reliability – how expensive is it? 4

The Bedrock Power Paradigm Legacy Paradigm Bedrock’s Paradigm Commodity mindset drives cost-based design Differentiated mindset results in holistic, modular, distributed design Thermally challenged Thermal bonding and contiguous conduction Open vented construction Sealed, metal construction Nominal design and component selection bake in excessive stress Advanced thermo & electromechanical design for component placement, lifespan, and efficiency “NO” value add - intelligence, communication, sensing, group isolation Embedded, advanced sensing, monitoring, analytics, diagnostics, & IIo. T capabilities Minimal galvanic isolation and regulation Extreme galvanic isolation architecture Bolt-on approach: logical and functional decoupling between UPS, ICS, PS Integral design: Physically, thermally, electrically, and logically coupled with the platform 5
