Global manufacturer; this resource is served by its official China website. Confirm the selected regional product, voltage and approvals.
Use the NDR-120 model for enclosure placement; select the output voltage separately from the electrical data sheet. A series-level mechanical archive does not establish identical geometry or certification for every output-voltage variant.


## In plain English

### What the equipment does

A power supply turns incoming electrical power into the voltage and form needed by connected equipment.

### A simple example

In a switchgear control panel, an AC-to-DC power supply can provide DC power for relays, controller modules and indication circuits.

### What the drawings help you do

Use an outline or mounting drawing to plan where the equipment fits and where it attaches. Use a connection drawing to trace its electrical interfaces. A 3D model helps coordinate space; check the manufacturer's installation requirements separately.

### Terms

- CAD: Computer-aided design files used to prepare drawings and models.
- Revision: The recorded version of a drawing or model.
