With our various solutions, we can meet your requirements in terms of space, durability, digital integration and reliability in control systems. From innovative to especially powerful or economical – you're sure to find the right solution for your needs among our switched-mode power supplies!

  • Can be used safely in various environments
  • International approvals
  • PROtop – communicative power supplies

Electronic load monitoring thanks to selective short-circuit and overload protection

Our power management systems offer intelligent and innovative solutions with our reliable electronic load monitoring systems. Modern machines and systems in particular rely on efficient, selective load monitoring systems. You'll find a wide range of modular solutions featuring a high degree of flexibility in our product portfolio. Not only are they suitable for a wide range of applications, they also save space in your panel and time during installation.

  • Integrated power distribution
  • Ensure selectivity and 30% space saving
  • topGUARD – IO-Link-capable load monitoring system

Uninterruptible power supplies

Our DC-UPS systems safely bridge power failures of up to 30 hours and ensure a reliable and uninterruptible power supply for automation components. This enables plant processes or communication equipment to continue operating without interruption. Five different battery modules of the DURAeco series are available for optimal system design. For short-term power interruptions of several 100 ms, we recommend our absolutely maintenance-free maxSHIELD buffer modules based on capacitor technology.

  • Full remote control
  • NEW: maxSHIELD DC Buffer

DC/DC Converters

Are you looking for DC/DC converters that can be easily connected directly in parallel to increase power or that can be connected in combination with an AC/DC converter redundantly and directly in parallel? The integrated ORing MOSFET in our PROtop AC/DC and DC/DC converters ensures that any internal short circuits are reliably decoupled and eliminates the need for additional diode modules. Equipped with a communication module, data transparency, remote controllability and constant status monitoring are not a problem for our power management solutions.

  • Isolation and reconditioning

Redundancy and diode modules

Our diode and redundancy modules are capable of decoupling two or more power supplies. Such a module can be selected for short circuit protection or for functional decoupling of power supplies. These modules are supplemented by our capacity module. It offers energy reserves so that, for example, circuit breakers can be triggered quickly and selectively.

  • For power increase and redundancy
  • Capacity module for extra energy reserves
  • Can be combined with our capacity module for higher power reserves

Communication modules

Our communication modules enable the connection of our PROtop power supplies and topGUARD electronic load monitoring to control systems. Our power management products can be combined with our Industrial Ethernet portfolio, our relays and semiconductor switches as well as our lightning and surge protection devices. This allows you to make universal use of your power supplies and offers a wide range of complete solutions. As individual as your requirements – we have the solution!

  • Future-proof power supplies with plug-in modules
  • Full data transparency and remote control
Highlight

Pre charge units

Pre charge units enable controlled, sequential ramp-up of industrial DC microgrids. This means that loads such as drives, motors, or complex load circuits can be started one after the other to avoid current peaks. Our pre charge units are available in several performance variants. Operating mode and switch-on delay can be set directly on the device. Further setting and diagnostic options can be selected via the optional communication interface.

  • Adaptable to any application
  • Extensive diagnostic options
  • Conforms to the DC Industry V3 system concept
