Industrial DC Power Supply for Security

The myVolts S-50-24 is a 24V switching power supply rated at 2.1A and 50.4W. It is built for security monitoring, PLC control systems, industrial control and transportation facilities that need a compact DC source.

Simple Wiring and Selectable AC Input

Installation uses simple wiring with a copper coil transformer for safe connection. The AC input range is selectable by switch between 85-132VAC and 170-264VAC at 47-63Hz, also accepting 240-370VDC. Cold start inrush reaches 45A at 230V and leakage stays below 2mA at 240VAC.

50.4W Output with ±10% Voltage Adjustment

The unit delivers 0-2.1A at 24V with ±1% voltage accuracy and 200mVp-p ripple. Inlet and load stability are each ±0.5% and efficiency is 86%. The adjustable range of ±10% on the DC voltage gives some headroom, while the 2.1A limit defines the maximum load.

Questions about this item

How do I confirm the S-50-24 is delivering the correct 24V output after installation?

Measure the DC output with a multimeter; it should read 24V within the ±1% tolerance under load.

What comes in the box with the S-50-24 and what must be sourced separately?

The unit includes the switching power supply with copper coil transformer and filter magnetic ring capacitor; AC input cable and DC output wiring are not included.

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

Set the selector switch to the 170-264VAC range for 230VAC operation; the unit will draw 0.65A at that voltage.
