Automatic Backup Converter Switch AVR-P for Seamless Power Transition

Automatic switching of the main converter (rectifier, station) of cathodic protection to the reserve converter in cases of:
- absence, loss or exceeding the permissible limits of the supply voltage of the main converter;
- failure of the main converter (absence of output voltage and converter current).
Use in typical systems of corrosion monitoring of underground steel pipelines, as well as for autonomous use at consumer facilities.
