24 V 5 A DIN-rail power supply

The myVolts Rail Switching Power Supply delivers a regulated 24 V output at 5 A from a 100-240 V AC input. It mounts on a standard 35 mm DIN rail for compact cabinet installation. The unit weighs very little and occupies minimal panel space.

Single-rail 24 V output

The critical specification is the fixed 24 V DC rail rated for 5 A continuous current. Voltage accuracy is held within ±1 % and ripple stays at 200 mV peak-to-peak. Efficiency reaches 85 % at full load. The half-bridge PWM design runs at 60 Hz switching frequency. Built-in protection covers overload, over-voltage, short-circuit and over-current with automatic reset.

120 W continuous capacity

At 120 W the supply comfortably runs industrial sensors, PLCs and small actuators in a 60 °C ambient. Headroom disappears when the combined load exceeds 5 A or when sustained ambient temperature pushes above the rated limit. The ventilated aluminium housing relies on natural convection, so restricted airflow will reduce the practical ceiling.

Questions about this item

What does the 120W rating mean for a system using this power supply?

It can deliver up to 120W continuously at 24V, supporting loads up to 5A with 85% efficiency and 200mV ripple.

How does the 100-240V input range affect where this unit can be used?

The wide AC input accepts mains voltages from 100V to 240V at 60Hz, making it suitable for global use without a voltage selector.

What does the 35mm rail mounting require for installation?

It clips onto a standard 35mm DIN rail; the hollow shell design aids heat dissipation in the -10°C to 60°C operating range.
