When in need of a frequency monitoring the choice is no longer restricted to the DFB, DFC, or PFB, which monitor the single phase systems monitoring. With the introduction of the DPD it is now possible to use this device which offers the possibility of monitoring the frequency of three phase systems with unparalleled precision and resolution, also thanks to the digital configuration facility.
