  • EN 61643-11, IEC 61643-11 compliance

The MLP range is a comprehensive series of AC surge protectors dedicated to LED lighting system. Some versions are equipped with an extra dataline surge protection (RS485 or DALI) in order to provide a full solution for LED systems with transmission features. By this way the MLP range is able to provide all the existing configurations with an efficient solution . MLP surge protectors are based on a powerful association of MOV and GDT components, able to protect LED system against huge surges without disconnection. In the worse case, the SPD will fail in safety condition. Indication of the SPD failure is performed through power supply cut off and/or through remote signaling feature.
