This uninterruptible power supply for DIN rail applications offers a high degree of safety in the event of a power failure. Thanks to its comprehensive features, our DUSH can be deployed in a multitude of applications in the fields of industry automation, plant engineering, building control systems, test and measuring technology, and information and communication technology.

Decoupling provides maximum flexibility

Thanks to the integrated DC/DC converter, the load and battery voltages work decoupled, allowing the DUSH to set new standards in flexibility. The buffer capacity can be precisely scaled to suit any application. As an example, this allows a 24V load circuit to be buffered using a battery voltage of 12V. This helps to save space - and money.

Informative and user friendly

Thanks to its 1.5" colour display, the DUSH can be easily configured and maintained. Four push buttons are provided, enabling intuitive navigation of the menu structure. During operation, the current operating parameters, together with warnings or notes, are shown in real time. A cost-optimised version without LCD and AUX output is available for Systems with a smaller form factor or difficult to access.

Availability is key

Battery health is the linchpin of an uninterruptible power supply. For this reason, the DUSH periodically checks its internal resistance and performs a continuous calculation of the state of charge and health of the battery. An integrated protective circuit prevents the battery from deep discharging in emergency power operation and thus causing irreparable damage. Thanks to an optional temperature sensor, the battery can be charged temperature compensated. This reduces stress and increases availability.

Can be connected universally

With a MODBUS/RTU interface as Standard the DUSH can be easily connected directly to the control level in intelligent industrial environments. Over 50 real-time Status values form monitoring, enabling the early identification of status changes or even failures. Numerous adjustable parameters make complete remote maintenance of the system possible. With the PowerCMC user interface, this information can be conveniently displayed and managed.
