12 automatic switches (feeders of outgoing lines) are usually installed in the cabinet. Automatic DC circuit breakers are highly reliable equipment of LS IS trademark. The use of this equipment made it possible to ensure the reliable operation of the UPSS board, and make its price more attractive in comparison with similar products of other manufacturers.

Direct current board of UPSS provides for the maintenance of stable constant output voltage for the system and automatic charge of storage batteries. During the power outage, UPSS board maintains a constant specified load during the set time. Protection against deep battery discharge is provided by the RC.

The front panel of the cabinet is equipped with LED indicators showing the status thereof and analogue measuring devices indicating the output voltage, as well as charging/discharging currents. The network settings are displayed on the controller display, or they can be viewed using the personal computer.

Communication is provided via RS-485 network with use of Modbus protocol.

Main UPSS functions:

  • redundancy between sections;
  • control of AB current charging;
  • control of charging/discharging AB current;
  • the voltage measurement on UPSS buses;
  • control voltage on the UPSS buses;
  • control of voltage ripple on UPSS buses;
  • light signaling of UPSS state;
  • protection against surge discharges;
  • tf remote signaling of state of UPSS equipment and position thereof;
  • control and measurement of collecting buses insulation resistance relative to ground;
  • integration into the APCS via the RS 485 interface.

Board of uninterruptible power supply system (UPSS)is designed to provide uninterrupted DC power supply for responsible consumers in conditions of potential de-energizing the supply mains. UPSS is used as a part of power supply systems of automation devices, relay protection, communication facilities and other equipment that requires uninterrupted power supply. The board is intended for use in networks of one- or three-phase AC by voltage 220 and 380 V, accordingly, with 50 Hz frequency and neutral connected.
