AT switching power supply

The myVolts S-50-24 is a 24 V, 2.1 A AT switching power supply rated at 50.4 W. It accepts a selectable AC input of 85–132 VAC or 170–264 VAC at 47–63 Hz and delivers a regulated DC output with ±1 % voltage tolerance. A copper coil transformer and magnetic ring capacitor support stable operation in industrial environments.

Suitable for fixed 24 V loads.

This unit suits builders powering PLC control systems, industrial automation or transportation equipment that require a steady 24 V rail up to 2.1 A. The ±10 % adjustable range covers minor trimming only. Buyers who need a wider output voltage range, higher current or multiple output rails should look at a different supply.

86 % efficiency at 50.4 W

At full load the supply operates at 86 % efficiency, drawing 1.1 A at 115 VAC or 0.65 A at 230 VAC. Ripple and noise are specified at 200 mVp-p with line and load regulation each held to ±0.5 %. Cold-start inrush reaches 45 A at 230 V, and leakage current stays below 2 mA at 240 VAC.

Questions about this item

How can I confirm the S-50-24 is delivering a steady 24 V after wiring it up?

Measure the DC output with a multimeter; it should read within ±1 % of 24 V and show no more than 200 mV peak-to-peak ripple.

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

The unit itself is supplied; you will need to provide an AC mains cable suited to your local plug and any DC wiring or connectors for the load.

Which input-voltage setting should I select on the S-50-24 for a 230 V mains supply?

Slide the selector switch to the 170-264 VAC position; the supply will then draw about 0.65 A at 230 VAC.
