In what sectors is this resistance used?
The main areas of application are industrial automation, energy.
For what types of applications is it used?
The product is used 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 RCE HP family has 7 models with power ratings from 300 W to 1800 W and the ohmic value ranges between 0.51 Ω and 7.5K Ω. The maximum voltage of use is 3000 V.
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 10 times the nominal power for 5 seconds and 2 times the nominal power for 2 minutes.
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 RCE at nominal power reaches a surface temperature of around 350°C.
Resistance is normally assembled in groups via rods and ceramic spacer bushings. Thanks to the elliptical shape, the RCE lends itself to be ventilated. The terminals in stainless steel are suitable for connection via cable terminals. If installed in a group we recommend keeping a distance between the resistances of at least 30 mm.
