01 High availability of secondary and power equipment

The main circuits diagram of the DC System take into account the peculiarities of the power supply of secondary systems and DC power consumers and allow the Customer to obtain equipment with full redundancy of the main components of the DC System. Special algorithms for diagnosing battery cells make it possible to monitor its condition during power supply to important consumers.

02 High reliability and quality of products

The high reliability of the Exonsys DC System, which is designed taking into account the peculiarities of operation at various electric power facilities, is confirmed by test reports in independent test centers.
The use of high-quality DC switching devices, power electronics and an efficiently organized manufacturing process allow us to provide the Customer with reliable electrical equipment that meets any special project requirements.

03 Convenient operation and maintenance

The placement of equipment and terminal blocks in the Exonsys DC System cabinets provides access for replacement, repair and maintenance.
An optimal set of indicating devices and a developed monitoring system allow you to quickly assess the state of the main parameters of the DC System.
QR codes on the facades of the equipment provide quick access to the equipment technical documentation and contact numbers of technical support center.

04 Guaranteed power supply reliability

Exonsys DC System ensures stable operation of power receivers sensitive to voltage drops in any direct current network operation modes, including due to low ripple level and maintaining stable voltage on undamaged sections in case of short circuits in the DC network. Continuous per-feeder control of transit without current injection into the network allows you to quickly determine the place of transportation.

05 Monitoring, diagnostics and control

Exonsys DC System is directly integrated with APCS and remote control systems of plants, information management systems (Supervisory Control And Data Acquisition - SCADA), adaptive distribution management systems (ADMS) and other data analytics systems using the comprehensive list of data protocols including IEC 61850. 
The control and monitoring system of low-voltage switchgear Assol supports diagnostics and equipment performance data transfer to the maintenance and repair system to enable on-site preventive equipment maintenance.

06 Low total cost of ownership

We leverage special prices for components by leading Russian and global manufacturers, our own machine fleet and a short production cycle to offer the best equipment price to our customers. Low maintenance frequency along with minimized costs and prolonged service life help to minimize the total cost of Exonsys DC System ownership.
