Introduction

DDR series is a DIN Rail type DC-DC converter with main features including DIN rail-type easy installation, ultra

slim width, 2:1 wide input voltage, fanless design, -40~+70℃wide operating temperature(-40~+80℃for DDR-480

series), 4kVdc I/O isolation, 150% peak load, current sharing, DC OK, adjustable output voltage and full protective

functions.

This series of models has various input options: 9~18V / 16.8~33.6V / 33.6~67.2V / 67.2~154V and various output

options: 12V / 24V / 48V and can be used for industrial & railway control, security control, communication system

and other fields. Suitable applications include DC buck/boost regulator, increasing system insulation level and

voltage drop compensation along cable...etc.

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.

Installation Manual

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

AWG 18 16 14 12 10

Rated Current of

Equipment (Amp) 7A 10A 15A 20A 30A

Cross-section of

Lead(mm2) 0.8 1.3 2.1 3.3 5.3

Note: 1. 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.

2. The maximum allowable wire cross-sectional area for the terminal of the

SDR-75 is 12AWG/2.5 mm2 .

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 shown as below.

（9）Mounting Instruction：

Mount as shown in figure only, with input terminals down, or else sufficient cooling will not be possible.

Admissible DIN rail：TS35/7.5 or TS35/15

For rail fastening：

（a）Tilt the unit slightly rearwards.

（b）Fit the unit over top hat rail.

（c）Slide it downward until it hits the stop.

（d）Press against the bottom for locking.

Installation Manual

（e）Shake the unit slightly to check the locking action.

（10）For other information about the products, please refer to www.meanwell.com for details.

Warning / Caution !!

（1）Risk of electrical shock and energy hazard. All failure should be examined by a qualified technician. Please do

not remove the case of the power supply by yourself!

（2）Risk of electric arcs and electric shock (danger to life). Connecting both the primary and the secondary sides

together is not allowed.

（3）Risk of burn hazard. Do not touch the unit in operation and shortly after disconnection!

（4）Risk of fire and short circuit. The openings should be protected from foreign objects or dripping liquids.

（5）Only install the unit in a pollution degree 2 environment (Note.1).

（6）Please do not install the unit in places with high moisture or near the water.

（7）The maximum operating temperature is 55°C for DDR-120 series , 50°C for DDR-240 series and 60°C for

DDR-480 series. Please do not install the unit in places with high ambient temperature or near fire source.

（8）The FG ( ) must be connected to PE (Protective Earth).

（9）Output current and output wattage must not exceed the rated value on its specification.

（10）Disconnect system from supply voltage:

Before commencing any installation, maintenance or modification work: Disconnect your system from

supply voltage. Make sure that inadvertent connection in circuit will be impossible!

（11）For continued protection against risk of fire, replace only with same type and rating of fuse.

Pour ne pas compromettre la protection contre les risqué d’incendie, remplacer par un fusible de même

type et de memes caractéristiques nominales.

Note.1: Pollution Degree 2 applies where there is only non-conductive pollution that might temporarily become

conductive due to occasional condensation. Generally refer to dry, well-ventilated locations, such as

control cabinets.
