## Long description

The Legrand 146712 single-phase switched-mode power supply 12V 54W Class II is a reliable power adapter and inverter designed for professional and residential electrical installations. It efficiently converts an input voltage of 100-240V AC into a stable, adjustable 12V DC output, providing a rated power of 54W and a rated current of 4.5A. Built with a Class II protection rating and a modular design occupying 3 modules, this power supply ensures safe and dependable operation for various low-voltage devices and control systems.
Advantages
This single-phase switched-mode power supply delivers high energy efficiency with a very low no-load power consumption of under 0.3 watts. The adjustable output voltage allows users to fine-tune the output between 10.8 and 13.8 volts to meet specific application requirements. Equipped with a double output terminal block, it facilitates convenient wiring and connection flexibility in electrical panels. The modular construction ensures seamless integration into standard distribution boards, saving space while maintaining high performance and safety standards.
Suitable for
Powering low-voltage electrical devices in residential installations
Supplying control systems and automation equipment in commercial buildings
Integrating into standard modular electrical enclosures and distribution boards
Applications requiring a stable 12V DC power source with an adjustable voltage range
When it may not be suitable
This power supply is not designed for heavy industrial applications that demand a power output significantly exceeding 54 watts or a higher current than 4.5 amperes. It is also unsuitable for outdoor environments unless installed inside a properly rated weatherproof enclosure, as it lacks built-in resistance to moisture and extreme outdoor conditions.
Key specifications
Input voltage: 100-240V AC
Output voltage: 12V DC (adjustable from 10.8 to 13.8V)
Nominal power: 54W
Rated current: 4.5A
Protection class: Class II
No-load power consumption: less than 0.3W
Module width: 3 modules

How to use
Installation should be performed by a qualified electrician in accordance with local electrical regulations. Mount the modular power supply onto a standard DIN rail inside a suitable electrical enclosure. Connect the 100-240V AC input wires to the designated input terminals and secure the low-voltage DC devices to the double output terminal block. Use the voltage adjustment feature to calibrate the output between 10.8 and 13.8 volts if the specific application requires precise voltage tuning before turning on the main power supply.
What to consider before purchase
Verify that the 54W power capacity and 4.5A current rating match the electrical requirements of your connected devices
Ensure there is sufficient space on the DIN rail within your electrical enclosure, as the unit occupies 3 modules
Confirm that the input voltage available on-site falls within the 100-240V AC range
Check that the installation environment is indoor and protected from moisture and dust
Usage recommendations: Always verify all wiring connections before energizing the system and ensure that the total load does not exceed the 54W nominal power limit to maintain optimal performance and longevity.
