Industrial DIN-rail power supply unit, metal casing

Mean Well

Mean Well 24V 20A 480W 2 in 1 accessory

SKU CH-0RQK-4BCHP

Three-phase DIN-rail supply delivering 24 V at 20 A for 480 W output from 340–550 VAC input

  • Delivers stable 24 V DC power for industrial equipment
  • 20 A output current supports high-demand three-phase loads
  • 480 W maximum power handles heavy continuous operation
  • Wide 340–550 V AC input suits global three-phase mains
  • 47–63 Hz frequency range matches standard industrial power grids

Three-phase DIN-rail power supply

This Mean Well unit delivers 24 V at 20 A for a maximum of 480 W. It is built for industrial control cabinets and automation systems that require a stable DC rail. The three-phase input accepts 340 to 550 V AC across 47 to 63 Hz. Installers mount it on standard DIN rail inside electrical enclosures.

Capacity and headroom

The supply provides 480 W continuously at the rated 24 V and 20 A. Loads that stay within this current draw will run without voltage droop. Peaks above 20 A will trigger protection and reduce available power. Systems needing more than 480 W must use additional or larger units.

Thermals, noise and power draw

Convection cooling keeps the unit silent because no fan is fitted. Efficiency at full load reduces waste heat, so the enclosure temperature rise stays moderate. Input current varies with the three-phase line voltage between 340 and 550 V AC. No acoustic noise is generated during normal operation.

Questions about this item

Will this unit accept the 340 to 550 VAC three-phase supply in my current panel?

Yes, the supply operates on any three-phase input between 340 and 550 VAC at 47 to 63 Hz.

What should I measure to confirm the 24 V 20 A output is working after installation?

With a multimeter on the output terminals you should read 24 VDC under no-load and the voltage should stay within regulation while drawing up to 20 A.

Does the package include mounting hardware or only the DIN rail power supply itself?

The box contains the 480 W DIN rail power supply unit; mounting clips and wiring accessories are sold separately.
