CBW

The CBW is a new type of Water Cooled Brake Resistor. It combines the advantage of water cooling with the high pulse load ability of the traditional aluminium housed Alpha resistors. The CBW can easily be fitted into compact constructions and it is possible to stack several resistors close without distance when resistor banks are required.

The steady state power range span is from 1.0 kW to 7.5 kW / component and the CBW can withstand pulse loads of up to 30 times these values for one second every 120 seconds.

Reinforced versions for Fault Ride Through (Energy Dump Resistors) for Wind Turbines, Solar Plants and Small Power Plants are available.
