Before you buy an industrial power supply or transformer component, you need to answer one question: are you powering a new cabinet or repairing an existing drive? That choice separates the 120W 24VDC DIN Rail Power Supply from the ABB APOW-11C Control Power Supply Board. The DIN rail unit is a new, general-purpose DC supply. The ABB board is a used, drive-specific replacement for an ABB ACS800-104 inverter module. This head-to-head helps you pick the part that matches the job.
Quick Verdict
If you're building a control cabinet and need a clean DC source for controls or small loads, the DIN Rail Power Supply is the direct choice. If you're servicing an ABB ACS800 inverter, the APOW-11C board is the targeted replacement part, supplied used. Think of the DIN Rail supply as the power source for a new panel and the ABB board as the internal component for an existing drive.
| Product | Price | Condition | Key Spec | Price Bar |
|---|---|---|---|---|
| 120W 24VDC DIN Rail Supply | $22.99 | New | 24V DC output, 5A, 120W | |
| ABB APOW-11C Control Power Supply Board | $80.00 | Used | Replacement board for ACS800-104 inverter |
Where the DIN Rail Supply Wins
The DIN Rail supply fits when you want a self-contained power source. It accepts 100-240V AC input and delivers a rated DC output with an efficiency rating of 85% or higher. Its 1.7 x 4.8 x 5.1 inch footprint is made for DIN rail mounting, so it sits neatly in a control panel. That makes it a straightforward choice for panels that need reliable DC power without tying you to a specific drive brand. It is the lower-priced option here.
Where the ABB Board Wins
The ABB APOW-11C wins when the job is drive repair rather than cabinet build-out. This board is a control power supply for an ABB ACS800-104 inverter module and carries the ABB model number APOW-11C. It is a 3-phase component, so it is intended for a specific drive assembly rather than a general-purpose rail. The unit has been tested and is fully functional.
Product Notes
120W 24VDC DIN Rail Power Supply

This is the part to reach for when you are starting fresh. It is a new supply with a 5A output and 120W capacity, so it can run a modest control loop, indicator lights, or small automation components. The $22.99 price makes it an easy default for general DC duties. The limitation is scope: this is a universal supply, not a drive-specific replacement, so it cannot stand in for an ABB control power supply board.
ABB APOW-11C Control Power Supply Board

If your ABB ACS800-104 inverter needs its control power supply board replaced, this APOW-11C is the specific part to consider. It is an ABB unit with model number APOW-11C and is a control power supply for that inverter module. The 3-phase design matches drive environments. The trade-off is condition and cost: this is a used board, not new, and the $80.00 price sits above the DIN rail supply. It has been tested and is fully functional, so it works as a dependable replacement.
Final Choice by Use Case
Choose the 120W 24VDC DIN Rail Power Supply for a new cabinet build, a general DC source, or any application that needs a fresh power supply. Choose the ABB APOW-11C Control Power Supply Board when you are repairing the inverter module it was designed for and need its replacement control power supply board. Matching the part to the machine matters more than the price gap here.
