SINUS/ISD 15P0082B8
USER MANUAL
3 - 9/14
Information on the peak power rating and the average power rating of the resistors must be obtained from the
resistor manufacturer. Alternatively if this information is not available then a large safety margin must be
incorporated to ensure that the resistors are not overloaded. Elettronica Santerno can supply suitable brake
resistor assemblies as detailed over.
By connecting these resistors in series and in parallel the braking capacity can be selected for the application.
The minimum resistance of the combination shouldn't be less than that specified in subchapter 3.3.3.
The resistor(s) must be specified to the maximum DC link voltage (810V for the 400V models, 420V for the 230V
models).
