The braking resistors with CLH51A and CLH61A support plate are supplied as a combination of support plate and integrated braking resistor. There is a choice of braking resistors with different ratings for each support plate.
Braking resistors mounted to the support plate may not achieve the load capacity specified in the table at 100% cdf. The specifications for the nominal power of the inverter can be observed in submounted operation at 4 kHz, 40 °C and 400 V.
