Pulse carrying capacity BWD500072FE
(without limitation the endurance)
This brake resistors cover any operation requirement in the range below the curve.
General set up:
1. Fundamentally, the usual cycle time is 120 seconds.
2. The casing temperature can be determined applying the average performance on the included
temperature diagram. The average performance can be determined as follows: Pm = P[W] x ED[%] /100.
If you add 5K to the respective value in the temperature diagram, you will have the casing temperature in
respect to the pulse capacity.
