NDR-75 power-supply envelope and terminal-access reference for panel layouts.

## In plain English

### What it 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 the selected manufacturer's drawings to check the equipment's size, mounting points and cable connections. The layout helps you plan where it fits and how it can be reached for maintenance. An illustrative 3D preview does not establish product dimensions or required clearances.

### Terms

- Voltage: The electrical potential difference between two points, measured in volts.
- Rating: A value stating the conditions for which equipment is specified.
- Schematic: A drawing showing function and connections rather than physical appearance.

Concept diagram: Incoming supply → Power supply → Required control power
A simplified explanation of how this item works. It does not show terminal wiring or an operating procedure.

## What it represents

Reserve space for both terminal wiring and access to the rail latch rather than using the housing envelope as the installation clearance.
Use the linked manufacturer mechanical original for dimensions and exact revision. This illustration is independently drawn, unitless and not to scale.

## How to read it

- Reserve input/output wiring approach and mounting-release access.
- The NDR-75 series model is not proof of identical mounting or geometry for adjacent product series or every output-voltage variant.

## Information to show or reference

- Identify NDR-75 and the selected output-voltage variant.
- Reserve input/output wiring approach and mounting-release access.
- Check manufacturer ventilation spacing and service removal.

## Important distinction

The NDR-75 series model is not proof of identical mounting or geometry for adjacent product series or every output-voltage variant.
