Reliable Three-Phase 24 V DC Power for Industrial Automation
The Finder 78.Y3.1.440.2414 converts a compatible industrial three-phase AC supply or high-voltage DC input into a stable 24 V DC output. Its 20 A rated current and 480 W output capacity make it suitable for supplying multiple compatible automation devices from a centralised DC power source. The adjustable output voltage allows installers to set the supply within the specified range, while its active PFC architecture helps improve electrical conversion efficiency.
Industrial power systems must accommodate varying load conditions while maintaining dependable output performance. The Finder 78.Y3.1.440.2414 incorporates a temporary 26 A current boost, a DC OK monitoring contact, constant-current limiting and integrated protection functions to support reliable operation. Its short-circuit protection uses automatic recovery, while thermal protection shuts the supply down under excessive temperature conditions. Correct installation requires consideration of connected load, input supply compatibility, ventilation, protective devices and the manufacturer's temperature derating requirements.
