S-60-12 Switching Power Supply – 12 V, 5 A, 60 W

S-60-12 switching power supply designed to convert mains voltage into a 12 V DC output. It can provide up to 5 A, with a maximum output power of 60 W, and is intended for integration into electronic equipment and fixed installations.

Main features

• Model shown on the unit: S-60-12.
• Output voltage: 12 V DC.
• Maximum output current: 5 A.
• Maximum output power: 60 W.
• Ventilated metal enclosure.
• Screw terminals for the AC input and DC output.
• Output voltage fine-adjustment potentiometer.

Compatibility and power sizing

It can be used with 12 V devices whose total power consumption remains below 5 A and 60 W. A suitable power margin should be maintained, taking into account the current peaks produced by motors, heaters, laser modules and other loads during startup.

Possible applications include LED lighting, control boards, small plotters and certain CNC projects, provided that the total system consumption is checked beforehand. It can also be used with a CNC Shield V3, although final compatibility will depend on the motors, drivers, configured current and other connected components.

It should not be considered universally compatible with every 3D printer, CNC machine or laser engraver. A 3D printer with a heated bed will normally require substantially more power, while some machines without a heated bed may also exceed 60 W once the hotend, motors, fans and electronics are taken into account.

Choosing an alternative power supply

For applications requiring a fully enclosed external power supply and simpler low-voltage connections, the 12 V 5 A external power adapter may be a more suitable option.

If the calculated consumption exceeds this unit's capacity, consider the 12 V 10 A 120 W power supply or the 12 V 15 A 180 W power supply. The correct option must be selected according to actual consumption, startup peaks and the required safety margin.

Installation and safety

• Check the input voltage marking and configuration before connecting the unit to a 230 V mains supply.
• Install it inside a suitable enclosure that prevents accidental contact with the terminals and provides adequate ventilation.
• Correctly connect the protective earth terminal.
• Use a suitable wire gauge, fuse or circuit protection, disconnecting device and cable strain relief.
• Perform all wiring work while the unit is disconnected from the mains supply.
• The mains-voltage installation must be carried out by a person with suitable electrical knowledge.
• Do not operate the unit while exposed to moisture, conductive dust or loose metal objects.

Output adjustment

The potentiometer allows a small adjustment of the output voltage. Any adjustment must be checked with a multimeter before connecting the load and kept within the voltage range accepted by the powered equipment.

This power supply is not a battery charger. A dedicated charging controller suitable for the battery chemistry and configuration is required.
