  • Wide AC 100-240 V input suits global mains supplies

Industrial 24 V power supply

The myVolts S-48-24 is a 48 W switch-mode unit that delivers 24 V at 2 A from a 100-240 V AC input. Its aluminium alloy case measures 85 x 58 x 33 mm and relies on natural convection for cooling. The supply suits industrial automation, LED displays, CCTV, 3D printers and similar engineering tasks.

Replaces open-frame or enclosed linear units

Builders moving from larger linear supplies gain a smaller footprint and lower operating temperature. The jump is worthwhile when space is limited, when 0-40 °C ambient operation is required, or when CCC, FCC and CE marks are needed for compliance. The 100 % burn-in test adds confidence for continuous duty.

Limited to 48 W and fixed 24 V output

The ADJ terminal allows only minor voltage trimming, not a wide range. Overload, over-voltage and short-circuit protection shut the unit down rather than fold back current. Natural convection demands free airflow around the 33 mm height; sealed enclosures above 40 °C or loads above 2 A will exceed the design limits.

Questions about this item

What are the exact mounting dimensions for the 85 x 58 x 33 mm aluminum alloy case?

The supply measures 85 mm long, 58 mm wide and 33 mm high, with a natural-cooling aluminium chassis that fits standard DIN-rail or panel cut-outs matching those centres.

Which terminals do I wire for AC input and DC output, and what is the common polarity mistake?

Connect live and neutral to the L and N pins for 100-240 V AC; the V terminal is +24 V and GND is 0 V — reversing V and GND is the frequent error that triggers the short-circuit protection.

When should I plan to replace the electrolytic capacitors inside this 48 W unit?

At the rated 0-40 °C operating range the capacitors typically last several years; expect shorter life if the supply runs continuously near 40 °C or in 95 % humidity, so schedule a preventive swap after 3-5 years in harsh environments.
