VISHAY INTERTECHNOLOGY ULDCR series of stainless steel braking/crowbar resistors provide industry-high pulse energy capability up to 3.46 MJ and pulse current capability up to 12 kA for alternative energy and other heavy-duty applications. Higher pulse load capacity versions built to customer specifications are also available. Draloric resistors are optimized as crowbar resistors for frequency converters for three-phase generators in wind power plants and pumped-storage hydro power stations. Devices provide a patented self-supported, extremely robust and compact modular design that is easily assembled into all of these applications. The resistors’ component materials are also resistant to salt water.
