In what sectors is this resistance used?
The main areas of application are industrial automation, energy and railway sector.
For what types of applications is it used?
The product is used: as a dynamic terminating resistor, as a basic element in harmonic filter circuits, as a basic element for neutral earthing resistors, as a resistance to start up motors, as a charge and discharge capacitor resistance in RC circuits as a base element for resistive loads.
What are the electrical specifications?
The RCPO family has 11 models with power ratings from 152 W to 1500 W and the ohmic value ranges between 0,068 Ω and 120 Ω. The maximum voltage of use varies depending on the model.
What are the overload conditions?
The resistance can be overloaded with respect to its nominal power based on the working cycle (insertion and rest time). For duration pulse less than one second, the overload permissible also depends on the ohmic value. For non-repetitive pulses the relation is 5 times the nominal power for 10 seconds.
What is the temperature of the resistance?
The temperature of the resistance depends on the power that it will dissipate. Numerous factors influence the dissipation capacity; please consult our technical data sheet for detailed information. The graph of the data sheet on page 2 shows the relationship between the temperature on the resistance and the power applied for a heating element placed horizontally.
The resistance can be mounted with the relative SC/SQ support brackets for models up to RCPO 500, or with the SO 50 or SO 60 centering discs for models from RCPO 600 onwards; in this respect, see the relative product data sheet. For a better heat distribution we suggest mounting it horizontally. The terminals made in stainless steel enable electrical connection through cable terminals. If installed in a group, we recommend keeping a pitch equal to 1.5 times the diameter of the resistance.
