DIN rail power supply unit 24 V DC/10 A, primary-switched mode, 1-phase. The SFB technology (Selective Fusebreaking Technology) can be also used to trigger standard power circuit-breakers quickly and reliably.

The new QUINT SFB power supplies are the third generation of QUINT POWER supplies offered by Phoenix Contact. These new power supplies boast a series of additional features providing increased functionality.

The SFB-technology (Selective Fuse Breaking Technology) has been designed to provide up to 6x the nominal output current rating for 12ms. This circuitry allows for individual device protection to activate, preventing the entire DC bus from collapsing.

• Six times the nominal current rating for 12ms


• Adjustable output voltage form 18-29.5Vdc


• Wide operating temperature range of -25° to 70° C with nominal operating temperature rating of 60°C without de-rating.


• Built-in load sharing capability for parallel operation and increased output current


• 5 Year USA warranty with optional TRABTECH no-fault warranty
