Calculation of Individual Harmonic Limits For Class D the Limits are related to Pmax which is the Maximum Active Power consumption ot the EUT during the test time. Pmax = 327.3 W ( measured over test time ) For the Pmax calculation the Active Power (P) is taken over every 16 periods and smoothed with an 1,5second filter.

Individual measurements for 2nd to 40th order:
Iavg Average value of the Individual Harmonic Current
in Ampere RMS
Iavg%L Average value of the Individual Harmonic Current
in percentage of the applicable Limit
Imax Maximum Individual Harmonic Current
in Ampere RMS
Imax%lim Maximum Individual Harmonic Current
in percentage of the applicable Limit
Limit Irms Individual Limit (100%) for the selected Class
in Ampere RMS
General :
- Maximum and Average values are calculatet over the full test-time
- The values marked with "***" are actual values which could vary
during test-time and are taken at the time of protocol printout.
- The individual measurements are taken over every 16 periods and
smoothed with an 1,5second filter.
Notes Harmonics Emission Measurement on a Laser Printer ================================================= A 400W heater inside the printer switches on every 16 seconds for about 2 seconds. For the evaluation of Pmax the active power is filtered with an 1.5 second filter. Pmax reaches about 325W. For class-D all harmonic current limits are related to that value.
