浪涌功率降额曲线
• SINGLE SURGE PERFORMANCE graph is good for NON REPETITIVE applications operating in an ambient temperature of 70°C or less.
For temperatures above 70°C, the graph power must be derated further linearly down to zero at 150 °C.
• To determine applicable surge power in continuous surge applications:
1. Identify allowable duration and peak power Psurge of single surge.
2. Determine ratio of surge duration / surge OFF time in application.
3. Calculate Papplicable backwardly according to Y-axis of SURGE POWER DERATING CURVE.
