When you are shopping for industrial power supplies transformers, the difference between a standalone power supply and a replacement control board can be easy to overlook. The MEAN WELL SDR-240-48 is a standalone AC-to-DC power supply. The ABB APOW-11C is a board for the ABB ACS800-104 inverter module. Each is built for a completely different job, so the right choice depends on what task is in front of you.
Quick Verdict
Pick the MEAN WELL SDR-240-48 if you need a new 240W supply that converts 100-240V AC to 48V DC. Pick the ABB APOW-11C when you are repairing an ABB ACS800-104 inverter module and need its control power board. The MEAN WELL is USD 52.00; the ABB is USD 80.00 - a $28 difference for very different hardware.
Comparison Table
| Feature | MEAN WELL SDR-240-48 | ABB APOW-11C |
|---|---|---|
| Price | USD 52.00 | USD 80.00 |
| Condition | New | Used, tested and fully functional |
| Function | AC to DC power supply | Control power supply board for ABB ACS800-104 inverter module |
| Mounting / Form Factor | DIN Rail Mount, metal casing, 63mm width | Board unit for inverter module |
| Input | 100-240V AC | 3-phase |
Price and Condition Considerations
The $28 price gap makes sense once you look at what each item is. The MEAN WELL is a new, general-purpose power supply that can be mounted directly on a DIN rail. The ABB is a used board intended for a specific inverter module, so its value is tied to that repair context. If you do not own an ACS800-104, the ABB board has little practical use. Conversely, if you need a replacement board for that module, the MEAN WELL cannot substitute.
Where Each Wins
The MEAN WELL SDR-240-48 is the better fit when your project requires a new, self-contained DC source for a control cabinet. The ABB APOW-11C is the only one of the two that works as a direct control power board for an ACS800-104 inverter module. Put simply, the choice comes down to whether you are adding a new supply or restoring a specific inverter.
Product Notes
MEAN WELL SDR-240-48 240W 48V 5A AC to DC DIN-Rail Power Supply 100-240v input
The MEAN WELL SDR-240-48 is a self-contained AC-to-DC power supply with a compact 63mm width and metal casing. It delivers 48V DC at up to 5A and lets you fine-tune the output voltage from 48 to 55V and the current from 0 to 5A, giving you flexibility inside a control cabinet. With efficiency up to 94% and active PFC, it is built for continuous industrial service. The operating temperature range of -25 to +70°C is another strong point. However, it is not a replacement board for an ABB inverter. If you are specifically troubleshooting an ACS800-104 module, this supply cannot fill that role, so it should not be your pick for an inverter repair job.
ABB APOW-11C Control Power Supply Board
The ABB APOW-11C is a control power supply board made for the ABB ACS800-104 inverter module, and this particular unit has been tested and confirmed fully functional. For anyone maintaining that specific inverter, this board is a direct way to restore the control power function. It is listed as a 3-phase board, which matches the module's power environment. Keep in mind that it is not a general-purpose power supply: you cannot wire it into a standard control cabinet to produce a clean 48V DC output. It is also a used component, so its history is not the same as a brand new unit. Buy it only if you are working on an ACS800-104.
Final Choice by Use Case
Choose the MEAN WELL SDR-240-48 if you are building or upgrading a control panel and need a new 48V DC power source rated at 240W. Choose the ABB APOW-11C if you are repairing an ABB ACS800-104 inverter module and the control power board is the failed part. Each product is the right answer for a different job.
