DC high voltage surge protection SPD


DC high voltage surge protection SPD are mainly used in the DC power supply lighting protection and over-voltage  operation protection function. 


Main features:

  • Use high quality varistor, with reliable high-quality assurance and stable performance

  • Modular design, can be charged plug, easy to test or replace

  • With remote alarm device, easy for remote monitoring

  • Adopt temperature control circuit technology, over-current and over-voltage double automatic protection circuit

  • With working and fault display, degradation status is clear at a glance 

  • Fast response time, large discharge current capacity, low residual voltage

  • Easy to install, maintain simple

Installation Method and Precautions:

  • The power connecting wire use multi-strand copper wire and not less than 6mm2, ground wire use multi-strand copper wire and not less than 10mm2. Connecting wire should be short, straight, thick. Ground Resistance: R 4
  • The front-end of DC high voltage surge protection SPD should be with appropriate fuse in series or be disconnected.  Must disconnect power when install, prohibited hot-line operation.
  •  Insert Lightning protection module in place correctly after finished installation, check if working normally.
  • When the DC high voltage surge protection SPD module fault display window indication red (remote communication terminal output an alarm signal), then means the SPD happen fault and should be replaced.
  • DC high voltage surge protection SPD not need special maintenance, just need regularly check if connections is loose, status indication is normal.
