DC-UPS and Buffer Modules

Our DC-UPS systems provide great flexibility and reliability and are very easy to install. A complete DC-UPS system consists of a control unit as well as a battery and power supply with suitable power for the application. In the event of a power failure, the battery is automatically switched on and supplies connected loads.


With FIEPOS, PULS presents a completely new and unique type of power supply that has been developed precisely to move the power supply out of the electrical cabinet.

Redundant Power Supplies

Power supplies with built-in redundancy can replace redundancy modules and do not rely as much on width. You get a secure system that is extra important in applications where downtime is costly. The power supplies have quick-connect contacts on both the input and output for quick and easy replacement in the event of a fault. This way, you never have to shut down the application to install a new power supply.

Redundancy Modules

With a redundant module from Puls, you get a secure system against internal faults on power supplies, which is particularly suitable in processes where downtime is costly. The redundant module can also be used in systems where you want to ensure the operation of sensitive loads. Input 1 is connected to the main unit which normally supplies loads and eg PLC.

AS Interface Units

The interface units supply AS-interface systems with voltage via the yellow AS-interface cable. The communication between the different slaves is modulated and is embedded in the output voltage of the power supply. Therefore, special power supplies are required that do not filter out the data information.
