## Description

DIN rail mount switching power supply, ideal for electrical panels and automation systems, provides stabilized 5V DC up to 2.4A from a universal 100-240V AC input. The compact 17.5mm design saves space, fanless passive cooling ensures quiet and reliable operation, and the protected terminals plus overload and overvoltage protections increase operational safety.
The HDR-15-5 power supply is a compact AC-DC converter, designed for mounting on a standard DIN rail in electrical panels. It delivers a regulated 5 VDC output at a maximum current of 2.4A, with a power rating of 12W, operating from an input voltage range of 100 - 240 VAC, which makes it compatible with power grids worldwide without any modification.
The fanless design ensures quiet 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 extra 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 regulated with a maximum variation of ±0.5% for input voltage changes and ±2% for load changes.
