A low pass filter is applied to the instantaneous energy output directly after multiplication. This filtering allows all instantaneous components to be removed resulting in a constant output frequency at constant energy input, even over a short period of time. The delay of this filter is about 200ms. The LED output is primarily used for calibration purposes. The Rated Condition Select inputs (R0, R1, R2, R3) and the Fast Mode Select input (FMS) allow different nominal output frequencies to be selected. The FMS input also allows selection between STANDARD mode and FAST mode. The LED output is active low. Figure 9 shows the LED output waveform. In FAST mode the LED pulse output is set to a nominal frequency of 5kHz at an input current of 16µARMS on both the current and voltage channels. The nominal output frequency of the LED pin is given by ����������������_���������������� = 5000 × ������������ × ������������ × |cos ����| 162 …(3) in FAST mode and by ����������������_������������ = ����������������_���������������� ��������_������������ …(4) in STANDARD mode where IVP and IIP are the analog input currents in µARMS on the voltage and current sense inputs, is the phase angle between the current and voltage signals and DF_LED is the LED divider selected by R0, R1, R2, R3 and FMS according to Table 3. The timing values given below are based on the nominal frequency value of the internal oscillator. tL = 1/fLED_FAST in FAST mode (fLED_FAST as per Equation 3) = 1/fLED_STD in STANDARD mode (fLED_STD as per Equation 4) tLP = 91.5ms when tL > 183ms in STANDARD mode = tL/2 when tL < 183ms in STANDARD mode = 69μs in FAST mode t LP t L |
