  • converter remote restarting;
  • converter remote switching-out\switching-on;
  • remote control of the switched on converter.
• The modules are adapted to the following telemechanic systems: «UNK-TM», «Magistral-2», «STN-3000», «SupeRTU-4», «SKAT», «ELSI-2000», «ELSI-T», «TELUR».
• The modules provide uninterrupted work without routine maintenance and repairs for no less than 6 months.
• The modules provide the option of operation from one or two feeds of supply mains.

• Possibility of energy supply from two different supply main feeders: the main and back-up (energy supply class – 1, according to Electrical Safety Rules).
• High accuracy of protection potential maintenance - up to ±0,5% and protection current maintenance - up to ±1% (in automatic operating mode).
• Set electric parameters at supply mains voltage variation from 176V to 242V and operability at supply mains voltage variation from 160V up to 250V.
• Automatic switching-out of the main converter (at main feeder supply voltage failure) and switching-on of the back-up converter.
• Automatic switching-out of the main converter (at output voltage absence in main converter output) and switching-on of the back-up converter.
• Automatic switching-out of the main converter (at main feeder supply voltage occurrence) and switching-out of the back-up converter.
• Automatic switching-out of the back-up converter (if back-up feeder supply voltage value overruns the set limits).
