The VP-2040 provides optional two pulse output outlets, one for
active energy pulse output and the other for reactive energy pulse
output. The user can self-define the type of energy, and the default
types are active energy input and reactive energy input. The user can
also forbid pulse outputs.
A typical wiring mode of external acquisition equipment is shown as
follows:

Attention
o Different pulse acquisition devices have different operating
modes. The pulse output port circuit provided by VP-2040 is
adopting the collecting electrode open-circuit mode, isolated
by optically coupled.
o For the collecting electrodes, open-circuit characteristics
should be in range 48V ≤ Vcc ≤ 50V for voltage and I ≤ 50mA
for current
The pulse outputs of VP-2040 correspond to the signal energy values
inputted into the meter, and they can also be called secondary side
energy values. When the user calculates the actual energy, the pulse
outputs should be multiplied by the CT and PT factors.
Each pulse does not represent one kilowatt-hour or kilovar-hour, so
the user needs to set a reasonable pulse constant. The maximum
setting range is between 1000 and 40000.
