special purposes

Application:

• Maintaining of the equipment operation when voltage depression occurs;
• Safely shutdown of machineries;
• Maintaining "a bridge" when switching between the power supplies;
• {Providing high discharging current in the equipment;
• Rapid electrical energy accumulation and further providing to the grid;
• Providing temporary electricity power for equipment while operating in autonomous mode;
• As an energy storage device in difficult remote equipment;
• As an power supply in single-use system;
• To improve the operational reliability of the equipment;
• Are used together with chemical and other current sources to extend the service life;
