  • Simple wiring and ±10 % voltage adjustment speed up installation

Industrial 24 V 2.1 A switching supply

The myVolts S-50-24 delivers 24 V DC at up to 2.1 A for a rated 50.4 W output. It is built for factory automation, PLC control systems, transportation equipment and similar industrial installations that need a compact, DIN-rail style DC source.

Check input selector and load before wiring

Verify the AC selector switch matches your mains: choose the 85–132 VAC position for 115 V nominal or the 170–264 VAC position for 230 V nominal, both at 47–63 Hz. Confirm the connected load stays within the 0–2.1 A range and that the ±10 % voltage adjustment covers any set-point requirement.

Efficiency, ripple and inrush in normal operation

Typical efficiency reaches 86 % with line regulation of ±0.5 % and load regulation of ±0.5 %. Output ripple and noise is specified at 200 mVp-p. Cold-start inrush peaks at 45 A on a 230 VAC line, while leakage current remains below 2 mA at 240 VAC.

Questions about this item

What comes with the S-50-24 and what must I source separately?

The unit is a 24V 2.1A switching supply rated at 50.4W with 86% efficiency. It includes an input-voltage selector switch for 85-132VAC or 170-264VAC. You must provide the AC mains cable, output wiring, and any enclosure or DIN-rail hardware.

How do I decide between the two input-voltage ranges on the selector switch?

Set the switch to 85-132VAC for 115VAC mains (input current 1.1A) or to 170-264VAC for 230VAC mains (input current 0.65A). Match the setting to your local supply to avoid damage.

What does the 200mVp-p ripple figure mean for my PLC or industrial control gear?

The output ripple and noise is specified at 200mV peak-to-peak. With load and line regulation each at ±0.5%, the 24V rail stays within ±1% overall, which is typical for PLCs and automation equipment.
