GCB Grid-Tie Controller For Wind Turbine

Created by: Super User

The GCB controller with dump load is used to rectify frequency-variable output voltage of the wind turbine generator to DC voltage before feeding into the grid tie inverter. It is not only protecting against overvoltage for the wind turbine system, but providing the replaced load when the grid is down. There are three different voltage protecting points you can set in the controller.

Features of 20kW controller
1.Wide input voltage range of 30 Vac-500Vac.
2.Flexible dump load point control and action point can be controlled by a toggle switch.
3.IP65 ingress protection ensures the controller working in outdoor and indoor conditions.
4.High efficiency ensures efficient power transmission.
