Zener Barriers with Electronic Current Limitation Series 9004

R. STAHL's 9004 series INTRINSPAK single-channel zener barriers are ideally suited to supplying field devices with intrinsically safe auxiliary power due to their electronic current limitation. They have a particularly good power yield and are available in many variants for circuits with a negative or positive potential, including for unregulated power supplies.

  • For supplying field devices with intrinsically safe auxiliary power, variants for many applications
  • Flexible, space-saving devices that are easy to install on a DIN rail
  • Reduced storage due to standardised back-up fuse
