Energy pulse output setting: energy pulse settings include Pulse Constant and Pulse
Width. Pulse Constant's range is 500-20000, Pulse Width range is 20-100ms. In practical
applications, Pulse Constant and Pulse Width should be set according to the system's real
power, otherwise it will influence the system's energy accuracy.
Pulse Period = 3600000 /(Real Power x Pulse Constant)
Pulse Period > Pulse Width
The following equation must be fulfilled in order to ensure the energy accuracy, the unit of
Real Power is kW, Pulse Width is ms.
3600000 /(Real Power x Pulse Constant)> Pulse Width
For example, if the Real Power is 35.2 kW, Pulse Width = 3600000 /(35.2 x Pulse Constant), it
must meet 3600000 /(35.2 x Pulse Constant)>Pulse Width.
Note: The voltage rating is set for alarm, as the voltage rating in the alarm settings.
