When you're choosing among industrial power supplies transformers, the first decision is about the role of the unit, not just the brand or the price. One side of this comparison is the Square D 9070TF100D1, a new Industrial Control Transformer. The other is the MW NDR-120-12, a 10A Industrial DIN Rail Power Supply with a 12V output. They both belong in industrial automation and electrical panels, but they are built for different jobs.
Quick verdict: If your setup calls for an industrial control transformer, the Square D 9070TF100D1 is the unit to select at $175.00. If your controls need a power supply rather than a transformer, the MW NDR-120-12 is the practical pick at $39.99.

Where each product wins
- Square D 9070TF100D1 wins when your panel calls for the transformer role and you want a new unit with a Square D part identity.
- MW NDR-120-12 wins when your cabinet layout asks for a rail-mounted power supply and you want a clearly specified output.
Product notes
9070TF100D1 Square D Industrial Control Transformer New USA
The Square D 9070TF100D1 is the dedicated control transformer in this head-to-head. If your design calls for an industrial control transformer rather than a power supply, this new unit gives you a clear part identity with MPN 9070TF100D1 and the Square D brand. It fills the traditional transformer role, which is exactly the side of the comparison it represents. The limitation is that it is not a low-voltage rail supply, so it won't replace the MW unit in a power supply application. For a panel that already specifies a Square D control transformer, this is the natural match; for a rail-mounted power supply job, it is the wrong category.
10A Industrial DIN Rail Power Supply, NDR-120-12 Output 12V Power Supply
The MW NDR-120-12 brings the power supply side of the comparison into focus. It is listed as a 10A Industrial DIN Rail Power Supply with a 12V output, 120W nominal power, DIN Rail Mount style, and an installation area covering indoor and outdoor use. Those details give panel builders a concrete set of specs to plan around. The limitation is that this is a power supply, not an industrial control transformer, so it won't act as a transformer in a control circuit. If the load needs 12V at up to 10A, the MW unit's ratings line up with the job; if a transformer is required, the Square D unit is the one to consider.
Final choice by use case
If your application is built around an industrial control transformer, choose the Square D 9070TF100D1. If your application centers on the power supply role, choose the MW NDR-120-12. Decide on the product role first: a control transformer won't be a power supply, and a power supply won't be a transformer.
