Reliable 24 V DC Power for Industrial Automation
The Finder 78.X1.1.230.2412 provides a regulated 24 V DC output for industrial equipment requiring a stable low-voltage supply. Its 10 A output current and 240 W power rating make it suitable for powering multiple compatible automation devices from a single industrial power supply.
Typical connected equipment may include programmable logic controllers, industrial relays, sensors, interface modules, electronic control circuits and other devices designed for operation from a 24 V DC supply.
The output voltage can be adjusted between 24 and 28 V DC. This adjustment capability is useful where connected equipment permits a higher supply voltage or where compensation for voltage drop along distribution wiring is required.
Any adjustment above the nominal 24 V DC setting must remain within the voltage tolerance of all connected devices. The permissible output current and power limits must also be observed.
Double-Stage Conversion with Active Power Factor Correction
Unlike simpler single-stage power supplies, the Finder 78.X1.1.230.2412 incorporates a double-stage switch mode architecture with active power factor correction.
Active PFC helps improve the relationship between the input current and supply voltage, reducing unwanted reactive power demand and improving the electrical characteristics of the input supply.
This technology is particularly valuable in industrial installations containing multiple electronic power supplies, where power quality and efficient use of the electrical distribution system are important design considerations.
The switch mode conversion process also enables the power supply to deliver substantial output power from a comparatively compact enclosure, making it suitable for space-conscious industrial control panels.
The Finder 78.X1.1.230.2412 is designed to operate from a wide range of AC and DC supply voltages.
Its 90–264 V AC operating input range supports common industrial and commercial single-phase mains supplies, while its 127–370 V DC operating range provides additional flexibility for compatible DC distribution systems.
The nominal AC input rating is 100–240 V AC, while the nominal DC input range is 140–338 V DC. Installers should distinguish between nominal supply ratings and the broader permitted operating ranges when specifying the unit.
This flexibility makes the power supply useful for industrial equipment intended for installation across different electrical supply environments.
Integrated Electronic Protection
The Finder 78.X1.1.230.2412 incorporates several electronic protection functions designed to support dependable operation and protect the power supply against specified abnormal conditions.
- Short-circuit protection: Hiccup-mode operation limits sustained fault conditions and supports automatic recovery after the short circuit is removed.
- Thermal protection: Internal temperature monitoring can shut down the output if excessive operating temperatures are detected.
- Overvoltage protection: Varistor-based protection helps manage specified voltage disturbances.
- Temporary peak current capability: Supports short-duration current demands above the continuous rating, within the manufacturer's defined limits.
These protective features do not replace correctly selected upstream circuit protection, suitable conductor sizing, appropriate earthing arrangements or compliance with applicable electrical installation requirements.
Parallel Operation and Redundant Power Systems
The Finder Series 78.X1 power supply supports parallel operation using appropriately selected external diodes. This provides additional flexibility when designing industrial power systems requiring increased load capacity or redundancy.
For increased-current applications, multiple compatible power supplies can be incorporated into a correctly engineered arrangement, provided their output settings, current sharing and protective requirements are considered.
For redundant systems, external diode arrangements can help prevent one supply from back-feeding another, allowing an appropriately designed installation to maintain power if one source becomes unavailable.
Parallel operation should be implemented in accordance with the manufacturer's application guidance rather than by assuming that direct output-to-output connections are permissible.
Professional DIN Rail Installation
The Finder 78.X1.1.230.2412 is designed for installation on a standard 35 mm DIN rail in accordance with EN 60715.
Its enclosure has a width of 63 mm, a depth of approximately 119 mm and a height of approximately 125.2 mm, providing a compact installation footprint for a 240 W industrial power supply.
Box-clamp terminals support secure electrical connections, while the DIN rail mounting arrangement allows the power supply to be integrated alongside other industrial automation and electrical control components.
The unit is specified for an ambient operating temperature range of −20 to +70 °C, with output derating required under applicable conditions. Appropriate enclosure ventilation, installation clearances and thermal management must be considered when operating in warm environments.
