Surge protection and interference filters

Effective protection

High-frequency, low-energy interference can be smoothed and eliminated using interference filters. Meanwhile lightning and surge protective devices provide protection against transient and high-energy voltage peaks.

Your advantages

  • Protection for all common applications and signals, thanks to the complete product portfolio
  • Versatile fields of application – designs and connection methods for every application
  • Space-saving and inexpensive installation, thanks to slim design
  • Easy testing, thanks to plug-in arresters
  • Protection against transient and high-frequency voltages with combinations of interference filters and surge protection

The protective circuit principle

The protective circuit provides seamless protection against surge voltages.An “effective protective circuit” helps to implement seamless surge protection.

And this is how it works:

Draw an imaginary circle around the object you want to protect.

Surge protective devices must be installed at all points where cables intersect this circle.

The area within the protective circuit is therefore protected in such a way that conducted surge voltages are prevented.

Consider the following areas during planning:

  • Power supply
  • Measurement and control technology
  • Data processing, telecommunications
  • Transceiver devices

Products

  • Surge protection for power supply units
  • Surge protection for renewable energy sources
  • Set solutions
  • Surge protection for measurement and control technology
  • Surge protection for information technology
  • Surge protection for transceiver systems
  • Interference filters
  • Test device for arresters

 Suppressor diodes

Properties:

  • The function is commonly referred to as fine protection.Graphic symbol for and U/I characteristic curves of a suppressor diode
  • Responds very quickly.
  • Low voltage limitation.
  • Standard version with low current carrying capacity and high capacitance.
    • At a nominal voltage of 5 V the maximum discharge capacity is approximately 750 A.
    • At higher nominal voltages the discharge capacity drops significantly.

Special features:

There are also diodes with a higher nominal voltage and greater discharge capacity. However, these versions are considerably larger and are therefore hardly ever used in combined protective circuits.

Key:

UR = Reverse voltage
UB = Breakdown voltage
UC = Clamping voltage
IPP = Peak pulse current
IR = Reverse current
