PSM PV

PSM PV is the range of devices for discharging induced transient overvoltages (Type 2 / Class II), for Photovoltaic installations, in accordance with EN 50539-11. DIN rail plug-in format. UL 1449 certified.

  • Suitable for all photovoltaic applications: large-scale, rooftop and self-consumption (off-grid) DC installations.
  • High discharge capacity with an 8/20 μs waveform. Imax: 40 kA
  • Exclusive devices for photovoltaic systems according to EN 50539-11. Maximum voltage rating 1500Vdc.
  • Remote and visual indication of protection device life status.
  • No back-up fuse required thanks to a dynamic thermal disconnection system with a breaking capacity of 10kA (Iscpv).
