The Finder 78.1D.1.230.2415 is a high-performance industrial DIN rail switch mode power supply designed to deliver dependable 24 V DC power for automation, machinery and electrical control systems. As part of the Finder 78 Series, this 130 W model combines a two-stage power conversion architecture with active power factor correction (PFC), adjustable output voltage and a dedicated pre-alarm contact for enhanced power supply monitoring.
The power supply accepts a wide 88–265 V AC input or 140–275 V DC input and provides a regulated output adjustable from 24–28 V DC. Its adjustable output enables engineers to compensate for cable voltage drops or optimise the supply for connected equipment, while integrated short-circuit, overload, overvoltage and thermal protection supports reliable operation in demanding industrial installations.
With a rated output power of 130 W and a nominal 24 V DC output at 5.4 A, the Finder 78.1D.1.230.2415 is suitable for PLCs, relays, sensors, actuators and other industrial control loads. A peak output current of up to 10 A for 5 ms helps accommodate brief inrush demands, while the integrated pre-alarm contact enables external monitoring of the power supply condition.
Industrial automation systems depend on stable 24 V DC power for PLCs, sensors, relays, actuators and interface equipment. The Finder 78.1D.1.230.2415 converts a wide-range AC or DC input into a regulated high-current supply, providing reliable power for machinery, manufacturing systems and control cabinets.
Unlike the positive-logic contact variant, the 78.1D.1.230.2415 incorporates a pre-alarm contact that can be integrated into a monitoring or control circuit to provide advance indication of an abnormal power supply condition. Combined with adjustable 24–28 V DC output, active PFC and comprehensive electrical protection, this makes the unit particularly suitable for automation systems where power supply status needs to be monitored.
