Uninterruptible power supply-DC

We manufacture customized power supply for DC systems with high availability and high efficiency and integrated distribution terminal.

Our solutions are based on a modular charge system from Eaton, -Eaton Access Solution (APS) in wall cabinets or floor cabinets. The system consists of 1-12 rectifier modules and a system monitoring module mounted in a 19 "rack. Thanks to the structure of paralleled rectifiers a system of N +1 redundancy are supported, just for increasing reliability. Rectifier modules can be replaced during operation without any parameter settings have to be done.
The system is easy to use thanks to a color display with perspicuous menus.
The system is monitored by the control unit and can be connected to a main control system via Ethernet interface and SNMP agent, Modbus TCP or the built-in web server. Alarm signal may also be obtained via potential-free contacts.

In the control unit parameters for optimization of battery charging can be settled.

Example of other benefits is temperature compensation of the charging voltage and protection of deep discharge of batteries.

The system has high efficiency including thanks to a special function; LBRS, Load Based Rectifier Shutdown. This function means that paralleled rectifiers gradually switches off if the load going down. Furthermore, the system can be optimized for operation with gensets.

Thanks to the possibility to combine different sizes of charging units the number of spare parts easily kept down.

To ensure the longevity of the batteries we used our proprietary battery control unit ABC2. ABC2 guaranteed that each individual block has exactly the correct charge voltage which will give longer battery lifetime and higher reliability.
