Introduction
TDR series is the next generation of Mean Well DIN rail power supplies with three-phase or high input range, this
three-phase DIN unit not only has a slim design of 110mm in width but also possesses a high efficiency of up to
94.5%. Like other Mean Well’s DIN series, they can be mounted on a TS35 Standard DIN rail. This are open type
device shall be installed in inside of appropriate enclosure or machinery.
Installation
（

）
Always allow good ventilation clearances, 20mm below, around the unit in use to prevent it from overheating.
Also a 10-15 cm clearance must be kept when the adjacent device is a heat source.

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.
