EN 50147-1 is a European standard specifically designed for the measurement of shielding effectiveness
Part 1: What Exactly is EN 50147-1?
- Filtering and shielding: Use common-mode chokes, feed-through capacitors, shielded cabling, and bonded enclosures where tests indicate vulnerability.
- Grounding and bonding: Proper equipotential bonding and separate functional/protective earth strategies reduce susceptibility and prevent unintended currents.
- Isolation: Optical or transformer isolation on critical control and signal channels limits disturbance propagation.
- Redundancy and fail-safe design: For safety-related functions, design so that equipment either continues correct operation or enters a safe state if electromagnetic disturbances cause faults.
- Layout and routing: Keep high-speed or noisy conductors away from sensitive inputs and follow best practices for PCB layout to minimize coupling.
- Component selection: Prefer components with proven EMI performance and adequate voltage/current margins.
