Allowable Frame Configurations
Follow these steps to ensure that a particular frame configuration is
within allowable power limits.
1. Using the figures listed in your frame requirements, calculate the
total per rail loading requirements for the positive rail and the
negative rail. The sum will be the total module loading requirement.
2. Compare the total loading requirements calculated with the
maximum frame loading specification of the frame in question.
3. Compare the total per rail loading requirements with the maximum
specified per rail loading of the power supply in question.
These comparisons must be
made for the +ve and -ve rails
independently.
