Designed to protect power circuits of machines, machines, mechanisms and other equipment from low-quality mains supply voltage, as well as an objective assessment of voltage parameters
mains supply.

Performs the functions of a recorder of the main characteristics of a 3-phase network.
Network characteristics are stored in non-volatile memory in the form of records, each of which includes:

- relay status
- measured network frequency
- the effective value of the voltage and current of each phase
- the amplitude value of the voltage of each phase
- phase angle AB
- angle of phase shift BC
- date and time of recording

Saving records is carried out with a frequency specified by the user (from 1 second to 10 minutes).
The number of stored records - 9000 pcs.

Includes:

- A traditional power voltage quality control relay with a maximum of monitored parameters.
- A recorder that records all the monitored parameters of this voltage into a non-volatile memory.
- Application program for a smartphone or tablet, which allows you to read data from the recorder and manage relay settings via a wireless interface.
