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.
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. 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.

Note: Current each wire carries should be de-rated to 80% of the current suggested
above when using 5 or more wires connected to the unit.
Make sure that all strands of each stranded wire enter the terminal connection and the screw terminals are
securely fixed to prevent poor contact. If the power supply possesses multi-output terminals, please make
sure each contact is connected to wires to prevent too much current stress on a single contact.

Use wires that can withstand temperatures of at least 80°C such as UL1007.
