The power controller measures the power consumption of single phases with the aid of current transformers and, if necessary, switches part of the load on/off to prevent the set current level from being exceeded. The measurement sample rate is 200 ms.

The device measures the power consumption of all three phases and forms them into a digital signal that is processed with the aid of a fast DFT (discrete Fourier transform). If the measured power consumption exceeds the limit value selected with DIP switches, the measurement is performed again after 200 ms. If the limit set for the power is still exceeded, phase 1 is switched off. Then, the measurement is performed again and if the power consumption has been sufficiently reduced, the value is saved and phase 1 remains switched off.

If the measured power limit is still exceeded after phase 1 has been switched off, phase 2 will also be switched off after three seconds. After this, the measurement is performed and if the power value has been sufficiently reduced, the value is saved and phase 2 remains switched off.

The phases can be switched back on when the measured power value is at a level where one of the phase loads that had been switched off can be switched on with an added load of 1 A. In other words, the combined value of the load to be switched on + 1 A + the measured power consumption must not exceed the limit value set with DIP switches. 

If more than one phase load has been switched off, the load that was switched off first is to be switched back on. If the power values do not allow the load in question to be switced on, the next possible load is to be switched on.

The above-mentioned operating principle prevents the transient changes caused by short circuits or motor start-ups from affecting the operation of the device. The used measuring system can also be used for measuring interfered current flow and impure sine wave.
