- CP stations have climatic modification - U, installation category - 1 and are designed for placement on open air.
- Maintenance-free period of CP stations - no less than 6 months.
- The rectifier is adapted to the main teleautomatic systems that are applied at JSC «GASPROM», JSC SC «TRANSOIL», JSC SC «TRANSOILPRODUCT» industries, regional gas-distribution organizations (GDO): «UNK-TM», «Magistral-2», «STN-3000», «SupeRTU4», «SKAT», «ELSI-2000» («ELSI-T»), «TELUR».
- The rectifier has low radio interference level not influencing other electric devices, communications, radio- and television broadcast that allows using it in community residential sectors.
- Steady operation in different climatic zones with ambient temperature range: from -45°C up to +45°C.
- Expansion of useful operating life up to 100000 hours, and service life - till 20 years.

- Automatic return to a present mode when energized after power supply failures.
- Steady operation during load droppings and surges.
- Effective overload and short circuit protection of load circuits.
- Effective lightning surge protection of load and supply voltage inlets.
- Circulating current drainage from the protected metalware to the anodic grounding electrode at the absence of mains supply voltage.
- Low power consumption due to high energy data and accumulating electric energy metering by a build-in meter.
- Electric safety of the maintenance staff provided by the earth leakage circuit breakers (UZO), automatically disconnecting CP stations from power line at a casual touch to current carrying circuits.
- Control of output voltage and load current by build-in measuring devices.
- Metering of time of energization and manual-on position of CP station.
