⚫ Introduction
SDR is a DIN rail power supply series with a 150% peak load capability (3 seconds) and high efficiency of up to 94%.
Like other Mean Well’s DIN series, they can be mounted on a TS35 Standard DIN rail.
⚫ Installation
（1）Always allow good ventilation clearances, 5mm left and right, 40mm above and 20mm below, around the unit
in use to prevent it from overheating.
（2）The appropriate mounting orientation for the unit is vertical, the input terminals at the bottom and output on
the top. Mounting orientations other than that, such as upside down, horizontal, or table-top mounting, is not
allowed.
