DC-power systems in combination with batteries have been used for many years.
In all fields of industry and commerce, the need for auxiliary power supplies to protect equipment against power failure is increasing.
Battery assisted DC power systems are used in a wide range of applications, such as monitoring and controlling of production processes, supply of measurement equipment, telemetry, telecommunication, and radio systems. These systems can be found in:
- Power plants and substations
- Chemical plants
- Petrochemical plants
- Railway equipment
- Offshore projects
- Oil and gas pipeline systems
