PULS: Capacitor-Based Buffer Modules – Fast, Reliable Bridging for Short-Term DC Power Interruptions
Capacitor-based buffer modules are ideal for applications that require a limited bridging time to safely shut down systems following a DC power outage. These modules provide a short but critical time window to transition equipment into a defined, de-energised state—minimising the risk of data loss or hardware damage. Early detection of voltage drops is essential for this strategy. Typically, this is achieved via the DC-OK signal at the output of the power supply. Once a drop is detected, the buffer module immediately takes over the load supply and maintains stable DC voltage until its stored energy is depleted.
