• Warranty period:
  - 2 years from putting into operation;
  - .5 years from delivery (shipping).

• Warranty period for transducers supplied to JSC "Transneft":
  - 2.5 years from putting into operation;
  - 3 years from delivery (shipping).

• Transducers operate in any selected mode:
  – protection potential automatic maintenance at the preset level;
  – protection current automatic stabilization and maintenance at the preset level;
  – output voltage and protection current manual setting;
  – periodical load current interruption by external control signal from supervisory system for polarization potential measurement on the construction.
  
• Convertors provide:
  – high accuracy of protection potential maintenance – up to ±0.5% and protection current – up to ±1% (in automatic operating mode);
  – set electric parameters at supply main voltage measurement from 176 V to 242 V;
  – smooth shift to set output voltage and load current values when energized, also at voltage fallouts and further mains voltage appearance;
  – load current pulsation factor less than 3% according to GOST R 51164-98;
  – transducers running time record;
  – load current limitation at overload and short-circuit in load circuit;
  – long trouble-free operation in the off-load mode, at the breakdown of the cable leading to the construction or anodic grounding;
  – steady operation at load resistance changes from 0.2 up to 5.0 of the nominal value (25 times!);
  – possibility of prompt switching to double nominal voltage mode (2 Unom) at half load current (0.5 Inom);
  – low energy consumption due to high energy data: efficiency output and cos;
  – low radio noise level as required by GOST R 51522-99. – load current pulsation factor.

• ambient air temperature range: from – 40°C to + 45°C;

Transducers are adjusted to main supervisory systems applied at the following establishments:
JSC «GASPROM», JSC «Transneft», JSC «Transnefteprodukt», regional gas-distributing organizations (GDO): «UNK – TM», «Magistral – 2», «STN – 3000», «SupeRTU - 4», «SKAT», «ELSI – 2000», «TELUR» and others.

Transducers provide remote control of:
- output voltage and current, protection potential;
- protection potential remote installation (in automatic mode – “AUT”);
- protection current remote installation (in automatic mode – “CUR”);
- output voltage remote installation (in manual mode – “MAN”);
- switching the convertor on and off;
- output current periodical interruption;
- unauthorized access inside the convertor.
