Load terminals are isolated and floating. Extensive protection, including over tempera- ture, over power, over voltage, over current and reverse polarity will help protect your valuable When selecting a DC load, it is important to Some applications may require high voltage/low prototype. consider not only voltage and current current and low voltage/high current which a requirements, but also power ratings. The power single load may not be able to handle. B&K The DC loads are easy to use. All parameters used when testing must fall within the hatched Precisions broad range of DC loads will allow can be set quickly and precisely from the front region for the appropriate DC load. you to select the optimal model for your panel, or programmed via RS232 or USB inter- requirements. faces.
