Current ratings: 

6-100 Amps.

Voltage ratings:

2-line (single phase) filters 250V-DC/50/60Hz, 120V-400Hz.
4-line (three phase) filters 440/250V-DC/50/60Hz, 220/120V-400Hz.

What is their application?

Filtering of power, information signals, signals and lines to control modules and telephone lines that must enter a shielded volume or other protected areas to reduce the risk of unwanted emissions.

Where are they widely used?

  1. Power filters - The main single-phase and three-phase installations for computer centers, in the automotive industry, shipbuilding, defense structures and other government organizations.
  2. Filters for control modules - for equipment such as lighting, elevators, alarm systems, doors, computer equipment in the above users.
  3. Telephone and communication filters for the above users.

How to specify the filter we need?

  1. Application; Maximum current consumption - in amperes for each phase
  2. Maximum current consumption - in amperes for each phase
  3. Voltage - VAC / VDC; Number of lines or phases
  4. Frequency - Hz
  5. Size / weight restrictions, if applicable
  6. Operating temperature - degrees Celsius
  7. DAMP in dB + frequency limits in Hz
  8. Impedance - in ohms;

All shielding components shown in the photos of the projects, implemented by our team belong to their respective manufacturers!
