Quality

We guarantee high quality standards thanks to the activation of strict security protocols and tested control procedures at every stage of the production process. The resistors, made of non-combustible materials are compatible with different IP degrees of protection.

Testing

  • Measure of the resistance value
    Verify that the resistance value is within the provided tolerance. This is carried out on all of the resistors of the batch.
    Equipment used: Milliohmmeter Burster Resistomat mod. 2316
  • Insulation resistance test
    Performed at a given continuous voltage – 1000 Vdc as a standard – applied between the terminals of the resistor and the metal can, for one minute. The measurement is carried out on 15% of the standard resistors and 100% of the custom resistances.
    Equipment used: Tester for Megger insulation resistance mod. MIT 515 – 5kV DC.
  • Dielectric rigidity test
    Performed at a given alternated voltage, 2500 Veff – 50 Hz as a standard, applied between the terminals of the resistor and the metal can, for one minute. The measurement is carried out on 15% of products in the batch.
    Equipment used: Equipment for test of dielectric rigidity equipment Weighing machines mod. EPK 520 – 5kV AC.
