Your project is on the bench or in the field, and you need power conversion hardware. Are you feeding electric locks on a door access system, or do you need a transformer for industrial control circuits? Those are different jobs, and the right pick changes with the application. A control transformer is built for industrial control circuits, while an access control power supply is built for door lock hardware. Here, the $12.75 Power Supply Control for Door Access Control goes head-to-head with the $175 Square D 9070TF100D1 Industrial Control Transformer. Both are new hardware in the industrial power supplies transformers space, but they solve very different problems.
Quick verdict
Choose the access control supply when your load is door access hardware like electric or electromagnetic locks. Choose the 9070TF100D1 Square D when you need an industrial control transformer for control circuits. If you're unsure, think about the load: electric locks need regulated power; control circuits need a transformer. They are not interchangeable, and wiring the wrong one can stall the whole installation.

Where each product wins
The access control supply is purpose-built for access control hardware. It includes short-circuit protection and a spray-painted metal housing that resists rust and deformation, making it a practical fit for door installations. Its compact, easy-to-install design is a plus in tight spaces.
The Square D 9070TF100D1 is an industrial control transformer from Square D, designed for the controls side of industrial equipment. If your panel calls for a control transformer, this model number gives you a clearly identifiable component to match to a design.
Product notes
12V 3A Power Supply Control for Door Access Control
This access control power supply controller provides a stable 12V DC output at 3A for electric locks and electromagnetic locks. It includes short-circuit protection, which improves safety and can extend the service life of the attached mechanism. The metal housing, finished with a spray painting process, is hard-wearing, rust-inhibiting, and resistant to deformation, making it a solid fit for door access installations. Its compact structure and easy installation add to its practicality. The limitation: it is a dedicated access control power supply, not an industrial control transformer. If your application calls for an industrial control transformer, this is not the substitute.
9070TF100D1 Square D Industrial Control Transformer
This Square D industrial control transformer comes in new condition and carries the model number 9070TF100D1. It is built for the control-circuit side of industrial equipment, making it a fit for projects that need a control transformer rather than a low-voltage DC supply. Because the model number and manufacturer are explicit, you can identify the part directly. The limitation is that it does not serve access control loads such as electric locks, which need a regulated 12V DC source. If your requirement is an industrial control transformer, this unit is aligned with that job; for door access hardware, it is not the right component.
Final choice by use case
For a door access system, electric lock, or electromagnetic lock, choose the Power Supply Control for Door Access Control. For an industrial control transformer application, choose the 9070TF100D1 Square D. Match the component to the load and your install has a much better chance of running right.
