Root Cause Analysis – Why?
• Addresses The Root Cause, Not Just The Symptoms
• Faulty Or Weak Components
• Power Or Environmental Issues
• Improperly Designed Circuits
• Underrated Components• Increased Reliability• Corrects The Weak Link
Why RCA Is So Critical to Agency Budgets
• Extend MTBF (Mean Time Between Failures)
• Save LABOR costs
• Saves MATERIAL costs
• Prevent DOWNTIME
• Drives you to the OPTIMAL solution
• Avoid major RETROFITS or overhauls
• Prevent CATASTROPHIC failures before they happen
WHAT TO LOOK FORSustainment Services
Repair• Diagnose component failures
• Replace faulty and degraded components
• Test and confirm proper operation
Upgrade• Perform Root Cause Analysis on failures
• Improve design, lessen or eliminate failure modes
• Assemble and test upgrade design, repeat if necessary
Manufacture New• Reverse engineer sample; Review performance requirements
• Develop engineering documents
• Manufacture and test first article and production units
Battery Charger – Under Rated Transformer
• Higher Power Transformer and Custom Adapter Board
• Higher Voltage Metal Oxide Varistors (MOVs)
• Replace all high failure parts including electrolytic capacitors, voltage regulators and resistors
Battery Charger UpgradeCase Study
Power Supply Drop In ReplacementCase Study
High Failure Power Supply
• Quasi resonant controller to reduce switching losses• Planar magnetics for lower losses• Skip cycle mode for low standby power• Cycle by cycle over current protection• Hiccup mode for continuous overload protection
• Provided as a Kit or Service
• High Failure Original Motor
• Contamination
• Large Maintenance Expense
• Drop in Upgrade Kit
• Reduction in Failure Rates
