Product introduce and application:

 

  

• DGM-type surge protector(hereinafter referred to as SPD)adapted to AC,mainly used for rated voltage not exceeding 1000V(RMS),200/380V,50/60Hz power supply system,not exceeding 1500V DC voltage of the circuit and equipment of the Surge Protection.SPD has a phase to phase(L-L),phase to ground(L-NE),phase to neutral(L-N),neutral to ground(N-PE) and combinations such as protected model.
• DGM-based high quality surge protector to use non-linear components and low residual voltage,small discharge current,modulus,and using safely and reliablely,designed and manufactured in accordance with the standards GB18802.1-2002/IEC61643.1,products have passed CE Certification and the national test Room:Beijing Lightning Experimental Device Type Detection Centers.
