Product Overview

The XDR-480 series is the pinnacle of MEAN WELL's DIN rail power supply technology — the most powerful, most efficient, and most feature-rich model in the entire XDR family. With 96% peak efficiency, parallel operation up to nearly 2 kilowatts (1920W), and full MODBus integration, it represents the state of the art in industrial DIN rail power.

In a 48mm slim profile (125mm deep), the XDR-480 delivers 480W from 85~305Vac input through the proven 80KHz PFC + 65KHz PWM + MCU dual-stage architecture. The 96% efficiency at 48V is the highest in the XDR lineup — only 4% lost as heat at full load, enabling sustained fanless operation in a compact form factor. Parallel operation scales to 1920W (3+1 redundancy) with active current sharing via CS/GND pins.

200% peak power delivers 960W for 5 seconds, with 600% transient peak current for 15ms — identical to XDR-240's exceptional surge capability. The full MODBus RS-485, ORing FET, DC OK relay, diagnostic LED, and remote ON/OFF feature set is present. All four standard voltages are offered, though 12V is derated to 360W (up from 240W on XDR-240).

UL61010 + HazLoc Class I DIV2, TUV, CCC, BSMI, EAC, DNV Marine, SEMI F47 certified. Triple IEC: 62368-1 + 61558 + 61010. 5-year warranty. 48x125.2x125mm, 1.1kg. 3 terminal types: Screw/LA/PI. Communication cable included.

Frequently Asked Questions

Why is the 12V model derated to 360W?

At 480W, a 12V output would require 40A continuous current. The XDR-480-12 delivers 30A (360W) due to current path and terminal limitations at this power level — the connector and PCB traces cannot practically sustain 40A in a 48mm form factor. For full 480W at 12V, consider paralleling two XDR-240-12 units. The 24V, 36V, and 48V models deliver full 480W without derating.

How does the XDR-480 differ from the XDR-240?

The XDR-480 doubles power to 480W in a 48mm chassis (vs 40mm). Upgrades: (1) 96% efficiency (vs 95.5%); (2) Parallel to 1920W (vs 960W); (3) Peak 960W (vs 480W); (4) 12V derated to 360W; (5) 15ms unified hold-up (vs 20ms — slight trade-off at higher power); (6) 30A at 12V (vs 20A); (7) 1.1kg (vs 0.79kg). Same feature set: MODBus, diagnostic LED, ORing FET, DC OK relay, 600% 15ms transient.

Can I really get nearly 2kW from four XDR-480 units?

Yes — four XDR-480-24 units in parallel deliver up to 20A x 4 x 0.9 x 24V = 1728W of usable output. The theoretical maximum at 48V is 10A x 4 x 0.9 x 48V = 1728W. The 1920W figure refers to the peak instantaneous capacity with 3+1 redundancy. For sustained operation, the 0.9 derating factor applies. This makes the XDR-480 platform capable of powering large automation systems that previously required multiple separate power supplies.

Is the 96% efficiency real-world achievable?

The 96% efficiency is measured at 230VAC input, full load, 25C ambient on the 48V model. In practice, efficiency varies from 94% (12V) to 96% (48V). At the higher end, the 48V model at 230VAC full load truly achieves 96%. This means only 20W of heat at 480W output — an extraordinary figure for a fanless DIN rail supply that explains how 480W is possible in a 48mm passive-cooled chassis.

Does the XDR-480 include the same diagnostic LED as XDR-240?

Yes — identical functionality. Green = DC OK, Red = DC Fail. Red pulse codes: 1 pulse = Overload, 2 pulses = Overvoltage, 3 pulses = Overtemperature, 4 pulses = Reverse voltage (ORing FET active), 5 pulses = System fault (AC UVP, communication, EEPROM). Red continuous blink = High ambient temperature warning. This field diagnostic capability is standard across XDR-240 and XDR-480.
