High-Capacity 24 V DC Power with Active PFC and Short-Duration Current Boost

The Finder 78.Y1.1.230.2412 converts a compatible single-phase AC or high-voltage DC input into a stable 24 V DC output using a double-stage switch mode architecture with active power factor correction. The regulated output supplies up to 20 A under specified operating conditions, making the unit suitable for industrial control cabinets with substantial low-voltage power requirements.

For applications involving brief increases in current demand, the power supply provides a 26 A boost capability for up to 3 s, together with a specified 26 A peak current capability for 5 ms. These functions can support compatible equipment with short-duration current requirements, provided the overall load profile remains within the manufacturer's limits.

The output voltage can be adjusted between 24 and 28 V DC. Integrated hiccup-mode short-circuit protection provides automatic recovery attempts during output faults, while internal thermal protection helps protect the unit from excessive operating temperatures. Its DIN-rail housing and screw terminals support integration into industrial electrical panels, subject to suitable ventilation, protection and installation clearances.
