The Finder 78.1A.1.230.2402 is a high-performance DIN rail industrial switch mode power supply designed to provide reliable 24 V DC power for automation, control panels and industrial equipment. As part of the Finder 78 Series, this model provides substantially greater capacity than the compact 12 W variants, delivering a nominal 120 W output for applications with higher power requirements.
The power supply operates from a nominal 120–240 V AC input and provides a regulated output adjustable from 24–28 V DC. Its adjustable output allows engineers to compensate for voltage drops or optimise the supply voltage for connected equipment, while integrated short-circuit, overload and overvoltage protection supports dependable operation in demanding control systems.
With a nominal output of 24 V DC at 5 A and 120 W rated power, the 78.1A.1.230.2402 can deliver up to 140 W continuously at 40 °C with a 230 V AC input. A maximum instantaneous current of 10 A provides additional capability for loads with short-duration starting or inrush requirements.
Industrial automation systems rely heavily on 24 V DC power for PLCs, relays, sensors, actuators, interface modules and other control equipment. The Finder 78.1A.1.230.2402 provides a regulated high-current supply capable of powering multiple control devices from a single compact DIN rail-mounted unit.
Its adjustable 24–28 V DC output enables compensation for voltage drops across longer wiring runs, while the ability to provide short-duration higher current makes the unit suitable for loads with demanding start-up characteristics. Integrated electrical protection and high operating efficiency further support dependable continuous service in industrial control cabinets.
