notes:
•
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 125°C.
•
To determine applicable surge power in continuous-surge applications:
1. Identify allowable duration and peak power P
surge
of single surge;
2. Determine ratio of surge duration/surge OFF time in application;
3. Calculate P
applicable
backwardly according to Y-axis of SURGE POWER DERATING CURVE.
