Product Overview

The XDR-240 series is MEAN WELL's most advanced 240W DIN rail power supply — the flagship of the XDR family with MODBus communication, parallel operation up to 960W (3+1), and 95.5% peak efficiency. It integrates industrial IoT connectivity with power supply management, enabling real-time monitoring, remote control, and system-level coordination previously requiring external hardware.

In a 40mm slim profile, the XDR-240 delivers 240W from 85~305Vac input with Active PFC (PF>0.98) and dual-stage 80KHz PFC + 65KHz PWM + MCU control. Four units can be paralleled via CS/GND current-sharing pins for up to 960W total output — a first in the XDR family. The bi-color LED provides 5 distinct diagnostic patterns (red pulses) for overload, overvoltage, overtemperature, reverse voltage, and system faults.

All XDR premium features are present: ORing FET reverse voltage protection, DC OK relay contact, remote ON/OFF (RC+5V_AUX short=ON), 200% peak power (480W for 5 seconds), and 600% transient peak current for 15ms — significantly longer than XDR-120's 4~10ms. The MODBus interface (D+/D- pins) provides access to output voltage, power, input voltage, and status parameters for integration with PLCs and SCADA systems.

UL61010 + HazLoc Class I DIV2, TUV, CCC, BSMI, EAC, DNV Marine, SEMI F47 certified. Triple IEC standard: 62368-1 + 61558 + 61010. 5-year warranty. 40x125.2x116mm, 0.79kg. 3 terminal types: Screw/LA/PI. Includes communication mating cable.

Frequently Asked Questions

How does the XDR-240 differ from the XDR-120?

The XDR-240 doubles power to 240W in a 40mm chassis (vs 30mm). Major new features: (1) MODBus RS-485 communication (D+/D-) for real-time monitoring and control; (2) Parallel operation up to 960W (3+1) with active current sharing; (3) 95.5% efficiency (vs 94%); (4) Diagnostic bi-color LED with 5 fault codes; (5) 600% 15ms transient (vs 4~10ms — 3.75x longer); (6) MCU-based control; (7) 20ms triple-unified hold-up at 277/230/115V; (8) 5V_AUX pin for remote control; (9) TC pin for transient peak enable/disable. The XDR-240 is the first XDR designed for Industry 4.0 smart factory integration.

How do I use the MODBus interface?

The XDR-240 provides D+ (Pin 8) and D- (Pin 6) for RS-485 MODBus communication, isolated from the output via GND_AUX (Pin 7). Connect to a PLC or PC via an RS-485 to USB converter. Read parameters include output voltage, output power, input voltage, and status codes. A communication mating cable is included with each unit. Full protocol documentation is available at meanwell.com/manual.html.

How does parallel operation work?

Connect up to 4 XDR-240 units in parallel with CS (Pin 4) and GND (Pin 3) interconnected. Requirements: (1) Disable transient peak (TC pin open); (2) Output voltage difference <0.2V between units; (3) Total current = rated current x units x 0.9 (e.g., 4x 24V/10A = 40A x 0.9 = 36A max); (4) Minimum load >5% of total; (5) Use short, thick parallel wiring. This enables up to 960W (3+1 redundancy) for large automation systems.

What do the LED diagnostic codes mean?

The bi-color LED provides immediate fault identification: Green = DC OK (normal); Solid Red = DC Fail; Red 1 pulse = Overload (>150% 115V / >200% 230V); Red 2 pulses = Overvoltage; Red 3 pulses = Overtemperature; Red 4 pulses = Reverse voltage (ORing FET active); Red 5 pulses = System fault (AC UVP, communication, EEPROM); Red blink = High ambient temperature warning. This eliminates the need for a multimeter during field troubleshooting.

Can I use the XDR-240 for high-inrush motor applications?

Yes — it's specifically designed for this. The 600% transient peak current capability lasting 15ms (vs 4~10ms on XDR-120) provides exceptional headroom for heavy motor starts, large contactor coils, and solenoid banks. After a transient event, allow 15 seconds before the next event. Combined with ORing FET reverse voltage protection, the XDR-240 is the most motor-friendly DIN rail supply in MEAN WELL's lineup.
