How the Finder 78.60 Switch Mode Power Supply Works
The Finder 78.60.1.230.2402 converts a suitable AC or DC input voltage into a regulated 24 V DC output using high-frequency electronic switching technology.
Switch mode power supplies use electronic components to control energy transfer efficiently, helping reduce the size, weight and heat generation associated with power conversion. This makes them particularly suitable for industrial control panels where space and electrical efficiency are important.
The Finder 78.60.1.230.2402 is designed to maintain a stable output voltage under normal operating conditions, supplying compatible 24 V DC equipment with dependable power.
Its 2.5 A rated output current provides up to 60 W at the nominal 24 V DC output. The connected equipment must remain within the supply's permitted electrical and thermal operating limits.
The power supply also provides a short-duration peak current capability of 5 A for 5 ms, which can help accommodate certain brief load transients. This is not a continuous-current rating.
Adjustable 24–28 V DC Output Voltage
A useful feature of the Finder 78.60.1.230.2402 is its adjustable output voltage.
The supply provides a nominal output of 24 V DC, which can be adjusted up to 28 V DC where required by the connected equipment and permitted by the application.
This flexibility can help compensate for acceptable voltage drops along supply cables or accommodate devices with specific operating voltage requirements.
The manufacturer's installation instructions recommend making output voltage adjustments slowly, preferably with a load connected.
The voltage setting must remain within the connected equipment's permitted input range. Increasing the output voltage does not increase the power supply's 60 W rated output capacity.
Integrated Protection for Industrial Reliability
The Finder 78.60.1.230.2402 incorporates several protective functions intended to support reliable operation and help protect the power supply from abnormal electrical conditions.
- Short-circuit protection: Uses an automatic recovery operating mode to respond to suitable output short circuits.
- Overload protection: Helps protect the power supply when the connected load exceeds its permitted operating conditions.
- Thermal protection: Provides internal protection against excessive operating temperatures, with a power reset required after certain thermal shutdown conditions.
- Input overvoltage protection: Uses a varistor to help protect against suitable voltage transients.
- Integrated input fuse: Provides an additional protective element within the power supply.
These integrated features do not replace appropriate upstream circuit protection, correctly sized wiring or safe electrical installation practices.
Support for Redundant Power Supply Systems
The Finder 78.60.1.230.2402 can be used in suitable parallel redundancy arrangements, allowing engineers to design systems where an alternative power supply can continue supporting a load if one supply becomes unavailable.
For automatic redundancy, the manufacturer's wiring guidance specifies the use of suitable external OR-ing diodes. These prevent unwanted reverse current flow between the connected power supplies.
Redundancy arrangements must be designed according to the manufacturer's instructions, with particular attention to output voltage adjustment, load current, wiring and protection.
The power supply must not simply be connected in parallel with another unit to increase output current unless the complete arrangement is expressly supported by the manufacturer's documentation.
Compact DIN Rail Installation
The Finder 78.60.1.230.2402 is designed for installation on a 35 mm DIN rail in accordance with EN 60715, making it suitable for industrial control cabinets, machinery enclosures and electrical distribution panels.
Its compact 70 mm width occupies approximately four standard modular spaces, helping electrical installers make efficient use of available panel space.
Screw terminal connections provide convenient wiring for the input supply and regulated DC output.
The unit should be installed with suitable ventilation and the clearances specified by Finder. Output current may require derating at elevated ambient temperatures, so thermal conditions must be considered during panel design.
