The service life and therefore the reliability of electronic ballast is determined by the failure rate of the construction elements used. The temperature is a fundamental parameter along with the electrical specification and quality of the elements.
In order to ensure the specified service life, all components of the VS electronic ballasts are designed so that they can be operated beneath the authorised limit values. All units run through several test stations during the production process to rule out premature failure due to hidden faults. Tests are performed on the components and measurements of the relevant data for operation are taken among other checks. Before delivery, the electronic ballast is subjected to a final Burn-In-Test.
