Industrial rail power supply

The myVolts rail switching power supply delivers 100W at 24V DC with 4.2A output current. It accepts a wide 100-240V AC input at 50/60Hz for global industrial use. The unit is built for automation environments such as printing, chemical, plastic, metallurgy and building material processes.

Sustained load behaviour

A work indicator lets operators monitor power output continuously during extended runs. An integrated fine-tuning switch allows precise output adjustment while the supply is under load. The industrial-grade design supports stable 100W delivery over long operating periods without derating.

Input voltage practical limits

The supply operates across the full 100-240V AC range at 50/60Hz without manual range selection. Output is fixed at 24V DC and 4.2A, so the connected load must match these ratings exactly. No other output voltages or current levels are available from this unit.

Questions about this item

How much heat or noise does the 100 W rail supply produce when it runs continuously?

The unit is a fanless switching design rated for 100 W at 24 V and 4.2 A, so it dissipates heat through its plastic-and-brass housing without audible noise.

What wiring or accessories must I already have to connect this supply to my DIN-rail panel?

You need a 100–240 V AC mains feed (50/60 Hz) and suitable ferrules or screw terminals for the DC 24 V output; the supply mounts directly on a standard DIN rail.

Will the fine-tuning switch let me match the voltage of an older 24 V PLC or sensor loop I want to keep?

Yes, the built-in fine-tuning switch adjusts the DC 24 V output so you can align it precisely with legacy 24 V equipment.
