Modular switching power supply designed for a wide range of industrial and domestic applications. With a stable output of 24V DC and a power output of 25W, it is perfect for powering low-voltage devices such as control systems and signals in SELV (Safety Extra Low Voltage) installations, meeting the safety standards of EN 60950-1.
Due to its small size, this power supply easily fits into tight spaces in electrical panels. The modular design allows for easy installation and maintenance, with a wide range of mounting options, including parallel connection for automatic redundancy and dual or series connection for different configurations.
The power supply has several internal protections, such as thermal protection that automatically shuts down the output in case of overheating and short-circuit protection with automatic reset. In addition, overvoltage protection via a varistor ensures that the device is protected against voltage spikes. With a test voltage of 4000V, this power supply is designed to operate under highly reliable and safe conditions.
It operates over a wide temperature range, from -20 to +50 degrees, ensuring stable performance even in harsh environmental conditions. Its IP20 protection makes it suitable for environments not directly exposed to dust or liquids, while its high dielectric strength (3000V AC between input and output) adds extra protection against short circuits and overvoltages.
