Water-cooled braking resistor increases vehicle energy efficiency
The unique design of the resistor allows excess energy generated during braking to be converted into heat and used in heating systems, increasing vehicle energy efficiency while reducing voltage transients. The REOHM BWD 330 operates at 800V and provides continuous power between 15,000W and 60,000W depending on the model. It is resistant to temperatures from -40 to +120ºC and is also capable of functioning properly under shock and vibration levels up to 100G. It is ingress protected to IP69K, meaning the device is resistant to high pressure spray-downs and shows no harmful effects on performance. The product also reliably protects the braking system in the event of a voltage transient (spike). Voltage transients occur when vehicles brake suddenly and the power is not rapidly dissipated. As the REOHM BWD 330 converts the braking energy into heat, the water-cooling system quickly transfers this into other processes such as heating.
By using a water-cooled design, braking energy dissipated as heat can be efficiently reused through a heat transfer. Footprint is also up to 88% smaller than conventional air-cooled resistors. The REOHM BWD 330 is certified to the latest automotive standards for mechanical and electrical components, including fire protection and electromagnetic compatibility.
