Electromagnetic Compatibility

EMC laboratories in EVPÚ a.s. belong to top-level workstations for EMC measurement. We provide type examinations of developed devices in accredited laboratories with state of the art measuring equipment and in large chambers. Our laboratories provide:

Measurement of:

• Low-frequency emissions
• Interference terminal voltage
• Interference field strength
• Radiated interference power

Measurement of resistance against:

• Electrostatic discharges
• Radiated high-frequency electromagnetic field
• Fast transients (Bursts)
• Surges
• Interference induced by high-frequency fields propagated through lines
• Magnetic field of mains frequency
• Short time voltage drops, short interruptions and voltage fluctuations
