 Introduction

General type with three phase or high input range is a DIN rail power supply series with a high input range,

340-550Vac. 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.

（2）The appropriate mounting orientation for the unit is vertical, the input terminals at the bottom and output on

the top for DRH-120, the input terminals on the right and output on the left for DRT-240, DRT-480 and

DRT-960. Mounting orientations other than that, such as upside down, horizontal, or table-top mounting, is

not allowed.

（3）Use copper wire only, and recommended wires are shown as below.

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.

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

（5）Recommended wire strapping length is 5mm (0.197").

（6）Recommended screwdriver is 4mm, slotted type.

（7）The recommended torque setting for terminals is 10 kgf-cm (9 Lb-in).
