EMC test results

IEC 61000-4-4 EFT test results

The VN340SP HSD is tested according IEC 61000-4-4 Level 4 (4kV). Power supply and input/

output ports are tested while all other channels are active. Table 9 lists test results.

Figure 48. Waveform switching inductive load:

VCC = 24V, L = 130mH, RLOAD = 48Ω,

f = 0.5Hz, Wave2 = VOUT, Wave3 =

VINOPT, Wave4 = ICH1OUT

Figure 49. Switching with short circuit: VCC =

24V, f = 0.5Hz, Wave2 = VSTATUSOPT,

Wave3 = VINOPT, Wave4 = ICH1OUT

Figure 50. Waveform ITOT and VSTATUSOPT

during the test with short circuit:

VCC = 28V, TA = 85°C, Wave4 = ITOT,

Wave1 = VSTATUSOPT

Figure 51. Waveform on ITOT and VSTATUSOPT

during the test with short circuit:

VCC = 28V, TA = –25°C, Wave4 = ITOT,

Wave1 = VSTATUSOPT
