Compact & reliable redundancy
02 June 2014
In critical applications where failure of the 24V power supply is not tolerable, redundancy – where two or more supplies are paralleled – is the preferred fail-safe solution.
In many conventional systems, diodes at the output of each supply ensure decoupling and isolation but suffer the problem of high inherent loss. At 20A load the loss per diode is around 10W requiring significant heat-sinking which needs to be dissipated by the cabinet’s ventilation system.
PULS has implemented a completely new technology in its YR-series of redundancy modules for load currents of 20-80A and input voltages from 12-60V where MOSFETs undertake the task of decoupling and significantly reduce this loss.
