Description
The ADEL System DFX1524A is an ultra-compact 24V DIN rail power supply designed for building automation, distribution boards and space-restricted control-panel installations. Manufactured in Italy, it combines a wide universal input range with a regulated 24V DC output in a compact, double-insulated enclosure.
The unit provides 24V DC at 0.65A continuously, equivalent to 15.6W at the nominal output voltage. A power-boost capability can supply up to 1.1A for a maximum of three minutes, helping the DFX1524A support short-duration start-up currents and temporary load peaks.
Its adjustable 22.5 to 28V DC output, high capacitive-load start-up capability, natural-convection cooling and automatic hiccup-mode recovery make it suitable for building controls, access systems, communications equipment and other professional 24V DC applications.
ADEL System DFX1524A 24V 0.65A DIN Rail Power Supply
An ultra-compact 24V AC-DC power supply with a wide input range, adjustable output and temporary power boost for building automation and control-panel applications.
The DFX1524A converts a wide-range AC or DC input into a regulated 24V DC supply for professional electronic equipment. Its extremely compact plastic enclosure supports DIN rail or wall mounting, making it particularly useful in distribution boards and installations where panel space is limited.
Typical Applications
This compact 24V DIN rail power supply is suitable for applications including:
- Building automation and management systems
- Access control and security equipment
- Distribution boards and shallow control panels
- Industrial control and monitoring systems
- Telecommunications and network equipment
- 24V sensors, controllers and field devices
Wide Universal Input
The DFX1524A accepts an 85 to 305VAC input and can also operate from 95 to 370VDC. This broad range supports use across standard 100V, 230V and 277V installations.
Temporary Power Boost
The power supply provides 0.65A continuously and can deliver up to 1.1A for a maximum of three minutes. This temporary boost helps support equipment with elevated start-up currents or intermittent load demands.
Reliable Automatic Protection
Integrated overload, overvoltage and short-circuit protection safeguards the supply and connected equipment. Hiccup-mode operation switches the output off during a fault and automatically attempts to restart once normal conditions return.
Flexible Installation
The compact Class II enclosure supports DIN rail and wall mounting. The unit can start capacitive loads up to 30,000µF, and up to four supplies may be connected in series where a higher combined output voltage is required.
Manufactured in Italy
The DFX1524A is manufactured in Italy by ADEL System for professional building-automation, residential and industrial power applications.
