Energy pulsing considerations

The meter’s energy pulsing LED and pulse outputs are capable of energy pulsing within specific limits.

Description Energy pulsing LED Pulse output
Maximum pulse frequency 2.5 kHz 25 Hz
Minimum pulse constant 1 pulse per k_h
Maximum pulse constant 9,999,000 pulses per k_h

The pulse rate depends on the voltage, current and PF of the input signal source, the number of phases, and the VT and CT ratios.

If Ptot is the instantaneous power (in kW) and K is the pulse constant (in pulses per kWh), then the pulse period is:
