When your control cabinet needs power, the first question is whether you're replacing a board or installing a transformer.
The ABB APOW-11C control power supply board is a replacement board for an ABB ACS800-104 inverter module, while the HPS PH100MQMJ is a 100 VA industrial control transformer for control circuits. The price gap is small - $80.00 for the ABB board and $76.82 for the HPS transformer - but the right choice depends on what your panel actually needs.
Quick verdict
If you're repairing an ABB ACS800-104 inverter module and need the APOW-11C board, that's the part to get. If you're building or servicing a panel that needs a 100 VA control transformer, the HPS PH100MQMJ is the component to mount. These two parts are not interchangeable; they serve different roles in a power system.
Comparison
| Consideration | ABB APOW-11C Board | HPS PH100MQMJ Transformer |
|---|---|---|
| Price | USD 80.00 | USD 76.82 |
| Condition | Used | New - Open box |
| Core role | Control power supply board for ABB ACS800-104 inverter module | 100 VA industrial control transformer |
| Phase | 3-Phase | 1 Phase |
| Mounting / wiring | Board-level replacement | Panel mount with screw terminals |
| Best for | Repairing a specific ABB inverter module | Adding or replacing a control transformer in a panel |
The HPS transformer costs $3.18 less than the ABB board, so the decision should come down to function rather than the small price difference.
Where each product wins
The ABB APOW-11C wins when you need the exact board for an ABB ACS800-104 inverter module. It's listed as a used but fully functional control power supply board, it's identified as 3-phase, and the model number APOW-11C makes it clear which assembly it's meant for.
The HPS PH100MQMJ wins when you need a standalone 100 VA control transformer. It's in new open-box condition, rated for 1-phase operation, designed for panel mounting, and it costs $76.82 - the lower of the two prices.
Product notes
ABB APOW-11C Control Power Supply Board
If you're servicing an ABB ACS800-104 inverter module and the control power supply board is the failed part, the APOW-11C is the direct match. It's described as used and fully functional, which can be a practical way to keep an existing module running without replacing the whole assembly. The board is labeled for 3-phase operation, and the APOW-11C model reference makes identification straightforward. The limitation is that this is not a general-purpose control power supply: it's tied to a specific inverter module family. If your application isn't related to that module, this board won't solve a broader control-power need. At $80.00, it's also the higher-priced item in this comparison, so it makes sense only when the board itself is what you need.
1 Unit ~ HPS PH100MQMJ 100VA Industrial Control Transformer 240x480V
The HPS PH100MQMJ is a 100 VA industrial control transformer sold as a single unit in new open-box condition. It's built for control circuits in machine-tool and panel applications, with a 1-phase rating, panel-mount design, and screw terminals that simplify wiring inside an enclosure. At $76.82, it's the lower-priced component here, and because it's a standalone transformer, you can install it wherever a 100 VA control transformer is required rather than matching it to a specific inverter module. The main limitation is its fixed capacity: if your control load exceeds 100 VA, this unit won't handle it. Also, since it's an open-box item, it's a good idea to inspect the unit on arrival for any visible transit damage.
Final choice by use case
Choose the ABB APOW-11C if you are repairing an ABB ACS800-104 inverter module and need the control power supply board itself.
Choose the HPS PH100MQMJ if you need a 100 VA control transformer for a panel or machine-tool control circuit and want the lower-priced, new open-box option.
