VEA Energy Absorber
Raycap’s Energy Absorber (VEA) is designed to protect wind turbine generators, inverters, converters, and photovoltaic systems.
In the case of a sudden (unexpected, uncontrolled) disconnection from the main electrical grid, high voltage/current pulses appear. The energy of such transients can reach up to 20 kJ or higher. Existing standard surge protection devices (SPDs) can only withstand a few kJ, whereas the VEA Energy Absorber is able to absorb and sustain high-energy long transients in a range of more than 20 kJ. The VEA is also able to withstand more than 1000 such hits.
All the while, Raycap’s Energy Absorber also serves as an excellent surge protection unit.
