Product Overview

The XDR-120E series is MEAN WELL's 120W economy slim DIN rail power supply, delivering a best-in-class balance of performance, certifications, and affordability. At just 30mm wide, it packs 120W into a compact chassis that maximizes panel space in crowded control cabinets while meeting global safety and EMC requirements.

The XDR-120E accepts 85~264Vac universal input (also 120~370Vdc), making it deployable worldwide without input switching. Available in four output voltages - 12V, 24V, 36V, and 48V - it delivers up to 10A at 12V and 2.5A at 48V. Efficiency peaks at 91% with ultra-low no-load consumption of 0.6~1W, reducing both energy costs and cabinet heat buildup.

A standout feature in the economy segment is the built-in DC OK relay contact (30Vdc/1A resistive) - enabling remote status monitoring for PLC/SCADA systems without additional hardware. This is paired with OVC III (IEC/EN 61558-1/-2-16 up to 2000m) and OVC II (IEC/EN/UL 61010-1/-2-201 and IEC/EN 62368-1 up to 5000m) overvoltage categories, plus SELV safety classification - providing industrial-grade protection at an economy price point.

The XDR-120E holds CB, TUV, UL/CUL, CCC, BSMI, EAC, KC, and BIS certifications spanning ITE (62368-1), industrial (61558-1/-2-16), and measurement (61010-1/-2-201) standards. With Class B EMC emissions (both conducted and radiated) and heavy industrial immunity (EN61000-6-2), the XDR-120E is qualified for residential, commercial, and light industrial environments where Class A compliance is insufficient.

Frequently Asked Questions

What makes the XDR-120E different from NDR-120?

The XDR-120E adds: (1) DC OK relay contact on all models for remote monitoring, (2) 4KVac I/P-O/P isolation, (3) OVC III certification, (4) IEC61010 measurement standard, (5) SELV classification, (6) Class B EMC, and (7) -40C minimum operating temperature (vs -20C). The NDR-120 is a basic industrial DIN rail supply; the XDR-120E is an upgraded economy platform with enhanced safety and monitoring at the same 120W level.

What is the difference between XDR-120E and XDR-120?

The XDR-120 is the premium tier with Active PFC (PF>0.98), ORing FET for reverse voltage protection, 200% peak power (240W/5s), 85~305Vac input, 94% efficiency, MODBus/parallel capability, DNV marine, SEMI F47, HazLoc, and 5-year warranty. The XDR-120E is the economy variant: no PFC, no ORing FET, no peak power, 85~264Vac input, 91% efficiency, and 3-year warranty - but retains OVC III, IEC61010, SELV, and DC OK relay at a significantly lower price point.

Does the XDR-120E have DC OK relay on all voltage models?

Yes. All four models (12V, 24V, 36V, and 48V) include a DC OK relay contact rated at 30Vdc/1A or 30Vac/0.5A resistive. This is a key differentiator from NDR series where DC OK is LED-only on some models.

Can the XDR-120E be used in residential environments?

Yes. With Class B conducted and radiated emissions (per CISPR32/EN55032) and harmonic compliance to EN61000-3-2 Class A, the XDR-120E is approved for residential, commercial, and light industrial use - a rare achievement for an economy DIN rail supply at this power level.

Is the BIS certification available for all models?

BIS IS 13252 (Part 1) certification is available by request but may not be stocked at all factories. Contact sales for availability confirmation before ordering for India-bound shipments. KC 62368-1 certification follows the same "by request" policy.
