The following table shows the different electrical power formulas in both AC and DC circuits. Quantity DC AC (1-Phase) AC (3-Phase) Power (W) P = V x I P = I2 x R P = V2 / R P = V x I x Cos Ф P = I2 x R x Cos Ф P = V2 / R (Cos Ф) P = √3 x VL x IL x ...
Yes, If you use the USB converter (As shown below). Install, Usb to RS485 Converter software. Unless you install the software, you can't communicate the meter via this converter. *** End of article ***
