REO damping resistors can absorb and temporarily store higher impulse loads. Thanks to the special winding technology, the wires of the damping resistors are separated spatially and therefore ensure a higher dielectric strength.
REO damping resistors are available in the protection classes IP00 to IP 65 and provide a high level of functional safety and service life.
UL resistors: The independent organisation “Underwriters Laboratories” (UL for short) has developed more than 1,300 safety standards. Many of these standards are in accordance with the American National Standards (ANSI) and, alongside the requirements for electrical safety for electrical items, they also often take into account additional requirements in relation to flammability.
High voltage resistors are subject to particular requirements as a result of their areas of application. The highest level of functional safety and service life paired with an extreme level of robustness against adverse environmental pressures are as a result absolutely essential.
REO high voltage resistors undergo the following tests:
- Climatic fluctuation testing
- Vibration and shock testing, simulated service life testing
- Self-heating measurement
- High voltage testing
- Insulation measurement
