EBW Series Manganin/NiCr Current Sense The EBW Series are manufactured using electron beam welding technology. This allows the joining of cErtificationS different alloys with great accuracy and tolerance. The EBW Series have heavy copper connectors, BN ES ISO 9001: 2008 excellent long term stability and low inductance. ISO/TS 16949: 2009 These components can tolerate soldering tempera- tures of 350C for 30 seconds or 250C for 10min. applicationS These can be mounted using re-flow soldering or Current sensors for hybrid power sources welding on copper. The EBWA can handle a power Frequency converters of 5W up to 100A at 0.5m. The EBWB can handle a constant power of 7W at 0.2m and a continuous High current automotive applications. load of 180A at 0.2m.
