This rating assumes the application load will be linearly decreasing from peak
braking power to zero braking as the process comes to a stop.
Check this rating against the module
’s duty cycle rating, and if it is higher than
rated, select the next higher rated module. If a duty cycle is required over
20%, please call for assistance with your application.

ONTINUOUS RATING
The continuous rating is listed for long term heating calculations should the
unit be installed in an area where heat dissipation is an issue. The rating is
based on a triangular cycle that starts at peak value and reduces to zero
within the rated duty cycle. Therefore, the average braking power during the
deceleration cycle is ½ the power required if full power were required during
the entire braking cycle. This value is:
