Multi-voltage power supply systems KONIS-PIP

Uninterruptible power supply system with various AC and DC voltages, type KONIS-PIP is designed for uninterruptible power supply in important industrial and similar facilities.

  • simultaneous supply with voltages 24, 48, 110 and 220 VDC and 230 VAC
  • maximum reliability of supply
  • redundant parallel operation of the rectifiers
  • redundant parallel operation of inverters
  • redundant parallel operation of DC / DC converters
  • modular construction – easy maintenance and servicing
  • selective disconnection of faulty modules in the event of failure
  • simple and intuitive overview of measurement, system status signals and chronological list of events
  • wide adaptation possibilities to every facility

The power supply system type KONIS-PIP is designed for uninterruptible power supply of specific DC  and AC loads whose reliable operation is of particular importance.

The system is designed on the basis of standard independent rectifiers, inverters, static switches, DC/DC converters and the battery. Rectifiers, inverters and DC/DC converters are modular and operate in a redundant parallel configuration, which further increases the reliability of the system.

The main system components are: rectifiers, battery, inverters, static switch, service switch, DC/DC converters, control unit and voltage distribution boards.

In case of failure of the mains supply, battery takes the role of energy source. After mains returns, rectifiers continue to supply inverters and DC/DC converters and simultaneous charge the battery.

In case of inverter failure, the static switch automatically switches over load supply to the mains.


The battery is a key component of reliability and availability of power supply. The system KONIS-PIP provides all the time battery charged and its recharging by precise DC voltage without ripple.

The operation of the power supply system is controlled by a microprocessor control unit, type KONLOG. It manages the system in real time and enables parameter setting, local and remote insight into measurements and signaling. Communication with the station computer, dispatch center and specialized service center is possible, which greatly contributes to reducing maintenance costs and to additional increasing of the reliability and availability of the entire power supply system.
