## Description

DIN rail power supply module for electrical panels, converts 100-240VAC to regulated 24VDC for automation, sensors, and control circuits. It provides 15W and up to 0.63A, has a compact 17.5mm housing, and passive fanless cooling for silent operation. It includes overload and overvoltage protection, with protected screw terminals for safe installation.
The HDR-15-24 power supply is a compact AC-DC converter, designed for mounting on a standard DIN rail in electrical panels. It delivers a stabilized 24 VDC output at a maximum current of 0.63A, with a power rating of 15W, from an input voltage range of 100 - 240 VAC, making it compatible with power grids worldwide without any modification.
The fanless construction ensures silent and reliable operation, with passive cooling through the aluminum housing. The slim 17.5mm width (1SU) allows multiple units to be mounted side by side on the DIN rail without taking up additional space. The covered screw terminals are protected against direct contact, meeting safety requirements for industrial installations.
The power supply includes built-in overload and overvoltage protection. The output voltage is stabilized with a maximum variation of ±0.5% for input voltage changes and ±2% for load changes.
