Challenges to Certify IEC 61850-3 Function Test EMC Test Wide Temperature Test Anti-Vibration Test Confidential

Unique Design to Conquer EMC Test Confidential

Wide Temperature Know-How Thermal Placement Optimization of Components Natural-Convection Chamber to Test Wide Temperature Components Database Optimal Heat Transfer Methods Self Warming System heat sources. It is particularly efficient as the main heat can be directly absorbed and dissipated from the sink. However, it takes a lot for hardware engineers to find out the main heat sources within the components. Meanwhile, it also contains a mechanism that can automatically raise the internal temperature when it is used in the extremely cold locations. It often requires lots of jobs to keep the system working either in the extremely hot or cold surroundings. Confidential

Special Heat Dissipation Design L-Type for Heat Dissipation Confidential

System Throttling Design High Temperature Solution: Dynamic Throttling Technique Safe User Configurable inside BIOS time Confidential

120 hours Uninterrupted Testing Confidential

Production Quality Management (Dynamic Burn-in) High temp. (55~75dc) Pilot Run 24~48hrs Room temp. (30~40dc) Mass Production 4~24hrs Wide temp. (-40~85 dc) W/T Product screen 24 hrs Over 80% function test items are covered during burn-in test program. Monitoring programs control the entire burn-in status, and show the data for analysis.
