Phoenix Contact 2866776 QUINT-PS/1AC/24DC/20 – 24 V DC, 20 A Power Supply
The Phoenix Contact 2866776 (QUINT-PS/1AC/24DC/20) is a single-phase, primary-switched DIN rail power supply from the Phoenix Contact QUINT POWER range. It delivers 24 V DC at 20 A (480 W), and the output can be adjusted from 18 to 29.5 V DC. Its SFB technology (Selective Fuse Breaking) can supply up to six times the nominal current for 12 ms. This trips standard miniature circuit breakers selectively, so only the faulty circuit is switched off and the rest of the system keeps running. The POWER BOOST reserve supplies up to 1.5 times the nominal current permanently, for starting loads with high inrush current.
