5 Function
5.1 Energy pulse output
The meter provides active and reactive energy metering, and the power data can be
transmitted and calibrated through 2 power pulse outputs.
Picture 5-3 Energy pulse output
(1) Pulse constant：5000 imp/kWh (all ranges), the meaning is when the meter accumulates
1kWh, the number of pulse output is 5000. It must be emphasized that 1kWh is secondary
energy data. If the meter is connected with PT or CT, 5000 pulse corresponds to primary energy
data 1kWh×voltage ratio PT × current ratio CT.
(2) Application example：the pulse counting device is used for PLC terminal. Supposing during
the period with the length of t, the number of collected pulse is N; the input of meter is
10kV/100V, 400A/5A, thus the accumulated energy of meter during this period is
N/5000×100×80 degrees of energy.
