DS50VGPVS-1000 Type 2 1000Vdc PV surge protector 2-pole

It comply with the European standard EN50539-11. The product is designed to be mounted on a DIN rail.

The plug-in protection module allows quick replacement in the event of a failure. The protective circuit with "VG technology" consists of a Y-diagram composed of Gas Discharge Tube and high-power varistors. The absence of leakage current prevents the surge protection from aging.

The DS50VGPVS-1000 is available with a status indicator and remote signaling.

DS50VGPVS-1000 surge protectors are connected in parallel on the DC network 

  • The total length of parallel connection wires to DC network must be lower than 0.5 m in order not to increase the protection level (Up) provided by the SPD.
  • Wiring is made by screw connections. On some models, a distribution bus can be used.
  • The protection wire coming from the SPD must be connected to the bonding bar of the electrical panel. Paralleling the protection wire with phases conductors must be avoided.
  • Local earthing resistance must be in compliance with the electrical rules.
