Mean Well XDR-E: A New Generation of DIN-Rail Power Supplies
XDR-E is a series of compact AC/DC DIN-rail power supplies that Mean Well launched in April 2025. It replaces three earlier lines — SDR, NDR, and EDR — which the manufacturer sold in nearly 100 million units over the past decade. This isn't a cosmetic refresh: the new models get a smaller housing, higher efficiency, and voltage options that simply didn't exist before.
In our catalog, XDR-E isn't just "one more series" either. We just retired all 10 NDR listings and replaced them with XDR-E — 17 SKUs ranging from 75W to 480W. If you previously bought NDR-120-24 or NDR-240-48 from us, the XDR-E equivalents now take their place.
How XDR-E Differs From NDR and EDR
The reason behind the switch sits in the datasheet, not the marketing copy. The XDR-E housing is 23-45% smaller depending on the model, so the same DIN rail now fits more equipment. Efficiency climbs to 96%, and the operating range extends to -40...+70°C — cold enough for an unheated outdoor cabinet, hot enough for a production floor next to a furnace.
- Dimensions: 23-45% smaller, depending on the power model
- Efficiency: up to 96%
- Operating temperature: -40...+70°C
- New output options: 12V/240W, 12V/480W, and 36V — configurations that NDR and EDR never had
- Parallel operation: up to 3840W combined for XDR-480E and XDR-960E
- Certifications: CB, TUV, UL, RCM, BSMI, CCC
The 12V models at 240W and 480W deserve a separate mention. Before, if you needed that much current at 12V, you either paralleled two units or moved to a bulkier industrial-class supply. Now one DIN-rail box covers it with a single SKU.
The XDR-E Lineup: What We Actually Stock
We carry the full range from XDR-75E to XDR-480E — 17 SKUs across different output voltages. XDR-960E exists in the manufacturer's lineup too, but we haven't stocked it yet — if you need 960W, check availability separately rather than assuming it's a ready-to-ship item.
| Series | Power | Output Voltages |
|---|---|---|
| XDR-75E | 75W | 12V, 24V, 48V |
| XDR-120E | 120W | 12V, 24V, 48V |
| XDR-150E | 150W | 12V, 24V, 36V, 48V |
| XDR-240E | 240W | 12V, 24V, 36V, 48V |
| XDR-480E | 480W | 12V, 24V, 48V |
Compared to the predecessor: our NDR lineup covered the 75-480W range with just four or five voltage options per power tier, while XDR-150E and XDR-240E now add 36V — useful for loads where 24V falls short and 48V is overkill.
Where XDR-E Fits
Most often this kind of supply goes into an automation cabinet — feeding a PLC, an HMI panel, sensors, and valves. What matters here is compactness and reliability across temperature swings, not record-breaking wattage.
- Machine and line control cabinets where DIN-rail space is already tight
- Outdoor telemetry and pump-station enclosures — the -40...+70°C range fits exactly these conditions
- Projects with N+1 power redundancy (see power supply redundancy)
- Setups that need more current than one unit provides — parallel connection up to 3840W on XDR-480E solves that
Should You Replace NDR or EDR With XDR-E
If NDR or EDR is already installed and working, there's no reason to swap it out mid-project — the series wasn't discontinued for defects, just superseded. For new projects, and as a replacement when a unit fails, we already recommend XDR-E: same price bracket, smaller footprint, higher efficiency.
The one thing worth checking yourself before ordering a replacement is the exact mounting dimensions in the datasheet, if your cabinet was designed tight around the old housing. Most of our customers swap it in without reworking the panel, but for a dense layout it's worth confirming the numbers first.
Frequently Asked Questions
How does XDR-E differ from the NDR and EDR series?
The housing is 23-45% smaller depending on the model, efficiency reaches up to 96%, the operating range extends to -40...+70°C, and there are new output options — 12V/240W, 12V/480W, and 36V — that NDR and EDR never offered.
What's the maximum power available in the XDR-E series?
Mean Well's lineup goes up to XDR-960E. In our catalog the top model right now is XDR-480E at 480W; we don't stock the 960E yet.
Can multiple XDR-E units be connected in parallel?
Yes, XDR-480E and XDR-960E support parallel operation for a combined output of up to 3840W — useful when a single unit can't supply enough current.
What temperature range can XDR-E handle?
The operating range is -40...+70°C, so the unit works in unheated outdoor cabinets as well as hot production environments.
Do you have XDR-960E in stock?
No, we currently stock 17 SKUs from XDR-75E to XDR-480E. XDR-960E isn't in our catalog yet — ask us directly if you need it.
What to Choose Instead of NDR
For most automation cabinets, XDR-E is now the direct replacement for the discontinued NDR series. Match the model to your load with a 20-25% margin: a 75-150W Mean Well power supply covers a small panel, while a busy cabinet with multiple drives needs 240-480W.
