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, with the input terminals at the bottom and the output at the top. Mounting orientations other than that, such as upside-down, horizontal, or table-top mounting, is not allowed.
3. Use copper wire only, and the recommended wires are shown below.
   AWG| 18| 16| 14| 12| 10
   ---|---|---|---|---|---
   Rated Current of Equipment (Amp)| 6A| 6-10A| 13-16A| 16-25A| 25-32A
   Cross-section of

Lead(mm2 )

| 0.75| 1.00| 1.5| 2.5| 4
Note:
1. The 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 that 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. The recommended wire strapping length is 5mm (0.197”).
6. The recommended screwdriver is 4mm, slotted type.
7. The recommended torque setting for terminals is shown below.
   Model| I/P| O/P
   ---|---|---
   SDR-75| 6.9 kg-cm (6 Lb-in)| 6.9 kg-cm (6 Lb-in)
   SDR-120| 10 kgf-cm (9 Lb-in)| 10 kgf-cm (9 Lb-in)
   SDR-240| 10 kgf-cm (9 Lb-in)| 10 kgf-cm (9 Lb-in)
   SDR-480/480P| 10 kgf-cm (9 Lb-in)| 8 kgf-cm (7 Lb-in)
   SDR-960| 10 kgf-cm (9 Lb-in)| 8 kgf-cm (7 Lb-in)
8. The suggested fuse and the maximum number of SDR PSUs that can be connected to a circuit breaker at 230V are shown below.
   Model| Fuse| Circuit breaker
   ---|---|---
   C16| D16
   SDR-75| T3.15A/L250V| 10| 12
   SDR-120| T4A/L250V| 7| 14
   SDR-240| T5A/L250V| 4| 8
   SDR-480| T8A/L250V| 4| 4
   SDR-480P| T8A/L250V| 4| 4
   SDR-960| F10A/H250V| 2| 2
9. Mounting Instruction： Mount, as shown in the 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 the top hat rail.
   • （c） Slide it downward until it hits the stop.
   • （d） Press against the bottom for locking.
   • （e） Shake the unit slightly to check the locking action.
10. For SDR-960, if your system must meet EN61204-3 Radiation class B. Then, attaching a ferrite core clamp filter to the AC cable, as close as possible to the AC source, can fulfill the radiated emissions requirements. The wiring is shown below. There are compatible models including ZCAT2235-1030A by TDK, ZCAT12V-BK by TDK, and KCF-130-B by KING CORE.

Warning / Caution!!

1. Risk of electrical shock and energy hazard. All failures 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 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 50°C for the SDR-960 series and 60°C for the SDR-75/120/240/480/480P series, please do not install the unit in places with high ambient temperature or near a 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. SDR-960 is a class A product. In a domestic environment, this product may cause radio interference in which case the user may be required to take adequate measures.
11. Disconnect system from supply voltage: Before commencing any installation, maintenance, or modification work: Disconnect your system from supply voltage. Make sure that an inadvertent connection in the circuit will be impossible!
12. 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.
