ApparentPower

Measured or calculated actual apparent power consumption including all auxiliary components (e.g. on a compressor including fans, controller, …).

Current

Measured or calculated actual root mean square of the electric power consumption including all auxiliary components (e.g. on a compressor including fans, controller, …).

Energy

Measured or calculated accumulated electrical energy consumed including all auxiliary components (e.g. on a compressor including fans, controller, …) since last reset.

Power

Measured or calculated actual electric real power consumption including all auxiliary components (e.g. on a compressor including fans, controller, …).

Voltage

Measured or calculated actual root mean square of the voltage applied including all auxiliary components (e.g. on a compressor including fans, controller, …).
