● Example of Setting
- Read data : Phase 1 Rms Voltage/Rms Current/Apparent power/Active power.
- Input Value : 220V, 1000A, PF 0.5
- Parameter : CT 1 : 1000, Input Frequency 55 ~ 65Hz, Overvoltage threshold 260V, Other is Default(0).
- Overvoltage Threshold = (260V(User Setting Value)-250V(defaultSetting Value))/0.2V.Resolution : 0.2V
- ex) OverCurrent Threshold = 1000A (User Setting CT 1 : 1000)=((1A(User Setting Value)-0.8(default
Setting Value))/0.001)*1000(CT).Resolution : 0.001A
* All of default value is 0
