5 IMMUNITY TEST RESULTS
5.1 Electrostatic discharge immunity
Electrostatic discharges (ESD) are the result of persons or objects that accumulate static electricity due to for instance walking on synthetic carpets. The ESD can influence the operation of equipment or damage its electronics, either by a direct discharge or indirectly by coupling or radiation. Both effects are simulated during the tests. Requirements Standard EN 55014-2 Basic standard EN 61000-4-2 Port Enclosure Performance criterion B; During the test degradation is allowed. No change of operating state or stored data is allowed. Air discharges 8 kV Contact discharges 4 kV
Performed tests Air discharges 4 kV √ 8 kV 15 kV xx kV Contact discharges 2 kV √ 4 kV 8 kV xx kV Via coupling planes √ Horizontal √ Vertical Polarity √ Positive √ Negative Set-up √ Table-top Floor standing Mode On mode Ambient temperature 21 °C Relative Humidity air 52 %
Observations During the test no loss of performance was observed. After the test the EUT functioned as intended. No unacceptable loss of performance was observed.
Conclusion: PASS
Version: 3.0
-page 23 of 30- 4323841.50
5.2 Electrical Fast Transient immunity
The EFT immunity test simulates disturbances by bursts of very short transients caused for example by switching off loads such as an AC motor or bouncing relay contacts. The transients are likely to disturb electronics but less likely to cause damage.
Requirements Standard EN 55014-2 Basic standard EN 61000-4-4 Performance criterion B; During the test degradation is allowed. No change of operating state or stored data is allowed. Pulse characteristics 5/50 ns 1 kV; AC input and output power port Peak Voltage; Port 0,5 kV; DC input and output power port 0,5 kV; Signal lines Repetition frequency √ 5 kHz 2,5 kHz
Performed tests Tested Voltage; Port 1kV; AC input power port Mode On mode Injection method √ CDN Capacitive clamp Polarity √ Positive √ Negative Set-up √ Table-top Floor standing
Observations During the test no loss of performance was observed. After the test the EUT functioned as intended. No unacceptable loss of performance was observed.
Conclusion: PASS
Version: 3.0
-page 24 of 30- 4323841.50
5.3 Surge transient immunity
The surge transient immunity test simulates the surges that are caused by over voltages due to indirect (induced) lightning transients. The pulse is a slow transient with high- energy contents and due to its long duration may cause damage to an unprotected EUT.
Requirements Standard EN 55014-2 Basic standard EN 61000-4-5 Performance criterion B; During the test degradation is allowed. No change of operating state or stored data is allowed. Pulse characteristics 1,2/50 µs EN 55014-2: Peak Voltage; Port 1 kV; AC input power port (line to line) 2 kV; AC input power port (line to earth)
Performed tests 1 kV; AC input power port (line to line) Tested Voltage; Port 2 kV; AC input power port (line to earth) Mode On mode Polarity √ Positive √ Negative
Observations During the test no loss of performance was observed. After the test the EUT functioned as intended. No unacceptable loss of performance was observed.
Conclusion: PASS

5.4 RF Conducted immunity
During this test the immunity of the equipment for induced or conducted electromagnetic fields is checked. Fields generated by radio and other transmitters cause RF voltages in long cables like the mains network. This test reproduces these induced disturbing voltages by injecting them to the EUT via the cabling.
Requirements Standard EN 55014-2 Basic standard EN 61000-4-6 Performance criterion A; Operation as intended Frequency range 0,15 – 230 MHz Modulation 1 kHz – 80% AM Test level; Port 3 V; AC input and output power port 3 V; DC input and output power port 3 V; Signal lines
Performed tests Tested level; Port 3V; AC input power port Mode Heating and lighting Frequency range 0,15 – 230 MHz Dwell time 3 seconds Injection method √ CDN-M3 EM clamp
Observations During the test no loss of performance was observed. After the test the EUT functioned as intended. No unacceptable loss of performance was observed.
Conclusion: PASS
