The Finder 78.Y3.1.440.2414 is a 24V DC 480 W switching power supply, delivering 20 A (26 A boost for 3 s) from a 380 to 480 V AC or 500 to 780 V DC input.
It takes three phase (two phase possible) input, adjusts from 24 to 28 V, has active, double stage power factor correction and signals through a DC OK contact.
It is 92% efficient at 400 V AC, delivers 26 A for 5 ms peak and has hiccup short-circuit protection (auto-recovery), thermal shutdown with auto restart and varistor overvoltage protection.
It mounts on DIN rail.
