24V DIN Rail Power Supply

This myVolts unit converts 100 to 240 V AC into a stable 24 V DC output rated at 120 W and 5 A. It mounts on a standard 35 mm DIN rail and operates from -10 °C to 60 °C with 85 % typical efficiency. Built-in overload, over-voltage, short-circuit and over-current protection shuts the output down automatically and resets once the fault clears. The compact, ventilated metal housing dissipates heat without a fan.

Installers needing 120 W at 24 V

Control-panel builders and automation engineers who need a single-phase 24 V 5 A supply for PLCs, sensors or relay banks will find the voltage accuracy of ±1 % and 200 mV ripple suitable. Buyers who require higher output current, redundant operation or a different output voltage should look at other models. The fixed 60 Hz input frequency also means the unit is not suited for variable-frequency sources.

120 W at 24 V decides fit

The 120 W rating sets the maximum load the supply can deliver continuously at 24 V. If the connected equipment draws more than 5 A the protection will trip, so total load must stay at or below this figure. The 35 mm rail mounting and 100 to 240 V auto-ranging input are fixed mechanical and electrical constraints that also determine suitability.

Questions about this item

How do I mount the power supply on a 35mm DIN rail and which step is often missed?

Clip the unit onto the rail until the latch clicks, then verify the housing is fully seated with no gap; the missed step is confirming the latch has locked rather than resting loose.

What maintenance will this 24V 120W supply need over time?

No scheduled maintenance is required; keep the ventilation slots clear of dust so the hollow-shell convection cooling stays effective and the automatic protection circuits remain responsive.

At what point does the 5A output hit its limit during continuous load?

The supply delivers up to 5A continuously; sustained draw at that level is the first limit, triggering overload protection if exceeded while the unit operates within the -10 to 60°C range.
