Uninterruptible power supplies
If process checks and communication processes are to be purposefully and safely maintained, then the automation components need an everlasting supply. Using our uninterruptible power supply units in conjunction with the suitable battery modules allows you to bridge longer network failures in an especially reliable way.
The modules can supply up to 40 A for 30 minutes or 1 A for 30 hours, depending on requirements. The modular design allows the complete load to be split into non-safe and safe load circuits, often enabling a smaller UPS to be designed.
The UPS control unit, together with the associated battery module and the power supply unit, forms a complete DC UPS system. In normal operation, the input voltage from the UPS control unit is connected directly to the load. In the event of a mains failure (drop of the DC input voltage) the system switches instantly to battery operation. Once the mains supply has been restored, the system switches back to normal operation and the battery is fully recharged by the integrated charger.Three relay outputs, as well as three additional active transistor outputs and a control input to lock battery operation, provide full remote control by means of PLC or DCS control. Numerous modes of operation and an easy-to-use status display provide rapid fault diagnosis and optimum customization to the application.
Electronic load monitoring
Modern machines and plants require load monitoring systems that are intelligent, efficient and reliable. Our portfolio of modular solutions offer high degrees of flexibility for a wide range of applications, while at the same time saving time and space during installation.
Efficient machine and facility operation calls for fail-safe and maintenance-friendly control voltage distribution that can be installed in a time and space-saving manner.
With the new maxGUARD system, the terminal blocks (previously installed separately) for distributing potential to the outputs of the electronic load monitors become an integral part of a 24 V DC control voltage distribution system.
The innovative combination of load monitoring and potential distribution saves time during installation, increases safety against failure and reduces the amount of space required on the terminal rail by 50%
The compact DC/DC converter provides systems with optimal failure protection for maximum availability.
