Type 2 PV surge protector

Part Number 481511
  • Type 2 surge protector for photovoltaic
  • VG technology
  • 1500 Vdc
  • No leakAge, no operating currents
  • Improved life expectancy
  • In/Imax: 15 / 40 kA
  • Common/Differential mode protection
  • Remote signaling

DS50VGPVS-G/51 products are available for PV networks with voltages of 600 V, 1000 V and 1500 Vdc. They comply with the European standard EN50539-11. The products are 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 is available with a status indicator and remote signaling.
