AC/Data surge protector for Led lighting system Class 2

Part Number: 721242

Specially developed spd with combined protection for 2-phase power supply (control phase):

  • Many variants available depending on application
  • With screw terminals or cable wiring
  • IP65 versions
  • For protection class I or II application
  • Developed for Uoc: 10 kV and Imax: 10 kA for highest outdoor requirements according to IEEE & ANSI
  • Optical error signalling

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.
