Industrial DIN-Rail Power Supply

The myVolts NDR-480-24 is a 480W industrial power supply designed for DIN-rail mounting. It delivers a stable 24V DC output at 20A from a wide AC input range of 90-264V AC and a DC input range of 127-370V DC. Built-in protections guard against short circuit, overload, and over-voltage events. This unit suits automation panels and fixed installations requiring reliable single-output power.

Suits panels needing 24V DC power

This supply fits builders wiring LED architectural lighting, stage fixtures, theater systems, or electronic displays that demand 24V at up to 20A. It is not suitable for systems requiring adjustable voltage outputs, multiple isolated rails, or output voltages other than 24V DC. Buyers needing battery-backup integration, redundant hot-swap modules, or non-DIN mounting formats should consider other form factors.

480W at 24V DC decides fit

The single 24V 20A rail provides exactly 480W of continuous power, which determines whether the unit meets your load requirements. Verify that your total connected equipment draws within this 20A limit at 24V DC. The wide 90-264V AC input tolerance supports global mains voltages without manual switching. Match the output specification precisely to your device ratings before installation.

Questions about this item

How is this DIN-rail power supply mounted and wired, and what step do installers often miss?

Snap the unit onto a standard DIN rail, then connect the AC input (90-264VAC or 127-370VDC) and the 24V 20A DC output terminals; the step often missed is verifying the input voltage selector matches the local mains before powering on.

What maintenance or replacement will this 480W supply need over time?

The internal cooling fan and electrolytic capacitors are the wear items; plan to inspect the fan for dust buildup annually and budget for capacitor replacement after several years of continuous 24V 20A operation.

What limit appears first when this unit runs at full 480W load for long periods?

Thermal protection triggers first; sustained 24V 20A output raises internal temperature until the over-temperature circuit shuts the supply down to prevent damage.
