Redundancy modules

PULS' redundancy modules are available with efficient MOSFET or economically priced diode technology. The modules secure highest reliability and availability in 1+1 and n+1 redundant systems.


High-efficient decoupling

Redundancy modules with MOSFET technology


PULS developed a decoupling solution with MOSFETs to fulfil the need for minimal no-load losses. For instance, when using a MOSFET module, a load current of 40A will only produce power losses amounting up to 3W.

With MOSFETs as a decoupling element, even voltage drops can be minimised. The voltage drop at 40A output current is lower than 50mV between the input and output.

After implementing MOSFETs, even the parallel-use mode achieves better thermal balance, thus leading to an extended lifetime of the power supplies. In this process, the load current is divided equally between the individual power supplies.

Cost-oriented decoupling

Redundancy modules with diode technology


PULS also offers redundancy modules based on the cost-oriented diode technology. The modules are suitable to set up reliable 1+1 and n+1 redundancy systems.

Their compact and light-weight design makes them a perfect fit for applications with little space.
