Able to withstand temperatures to 400°C, IRC's WDBR Series of thick-film planar dynamic braking resistors on insulated stainless steel substrates replace bulky wirewound devices. The fireproof devices are available in resistance ranges from 12 to 150 O with tolerance to ±10% with a minimum dielectric withstanding voltage of 2,500 VDC and inductance values from less than 3 µH to less than 6 µH. Maximum pulse power for the dynamic braking resistors is 1.5kW, 2kW, 3.5kW, 5kW and 7kW. Custom designs and resistance values are also available.
