■ Product Overview

Crowbar resistors are mainly used in the low-voltage ride through technology of wind power inverters. This product uses specially made aluminum alloy profiles as conductive heat dissipation bodies. To increase its heat dissipation area, each heat dissipation fin has small ripples. It uses PTC as the heating element inside and is finely crafted. It is used on the rotor side of wind turbines to bypass the rotor side converter. When there is a low voltage disturbance in the power grid, prevent the DC bus voltage from being too high and the rotor current from being too large. Mainly working in fault state, damping stator magnetic flux. Crowbar resistors can dissipate huge amounts of energy in an instant.
