## Description

DIN rail mounted switching power supply, ideal for electrical panels and automation systems, provides stabilized 12V DC up to 1.25A from a universal 100-240VAC input. The compact 17.5mm design allows installation in tight spaces, operates silently without a fan with passive cooling, has protected terminals, and includes overload and overvoltage protection.
The HDR-15-12 power supply is a compact AC-DC converter, designed for mounting on a standard DIN rail in electrical panels. It delivers a stabilized 12 VDC output at a maximum current of 1.25A, with a power rating of 15W, operating from an input voltage range of 100 - 240 VAC, making it compatible with power grids worldwide without any modification.
The fanless construction ensures quiet and reliable operation, with passive cooling through the aluminum housing. The slim profile of only 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 stabilized with a maximum variation of ±0.5% for input voltage variation and ±2% for load variation.
