| XPM230-Pulsed Output | The meter provides two pulsed outputs, both pulsed outputs are passive type. The first pulsed output is configurable. The pulsed output can be set to read total / import / export/ kWh / kVarh. The pulse constant can be set to generate 1 pulse per: 0.001(default) /0.01/0.1/1kWh/kVarh. The second pulsed output is non-configurable. It is fixed to read total kWh.Rate can be set to generate 1 pulse per: – 0.001 = 1 Wh/VArh (default)- 0.01 = 10 Wh/VArh – 0.1 = 100 Wh/VArh 1 = 1 kWh/kVArh – Pulse width 200/100/60 ms. |
